Big indicators, milky substance like shown, and the antifreeze overflow container level rises with water and dirty sludgy water. If running long enough water inside gets hot and bubbles from air flowing in. Can cause your container to also crack. Great video!
A very easy way to tell whether you have a blown gasket is to just remove the oil. If water falls out first then the gasket is blown. Because oil sits on top of water.
Oh, sure. It's very easy to drain the oil and buy more oil to put back in. Much easier than using the proper tester or observing the radiator cap opening for bubbles as described in this video. Fkn donut.🙄
I did all those tests and could not find my blown gasket - but the following test showed the problem - remove radiator cap and bring level into view - bring a cylinder u want to test to top dead center on ignition stroke [both valves closed] put compression test hose or extension [without check valve in it] into spark plug hole - attach shop air to supply shop air at 100 psi into cylinder on a warm engine - observe coolant in radiator for rise in level or bubbles.
Good experience, many thanks for sharing your experiment, i have the same problem with car. could share more, i am a automotive technical service at college so i love to hear from you. thank you so much,
Good stuff. Here's another tip, it happened to me once: I pressurized the cooling system, looking for any water leaks. Well, if your equipment is working well (no air leaks out the pump itself or via the radiator filler neck) the system should maintain a steady pressure reading at about 12 psi (I believe. Sometimes I only fill to 7) if pressure drops within 5 minutes, I look for signs of water, on the ground, around the engine. Well, I didn't see any water anywhere..which lead me to believe that water was being lost inside the motor due to a blown head gasket.
What kins of color was this water? Me and my buddies audi a4 has oil in the coolant reservoir. We were working on it today and it was dripping a white opaque water below the engine for about 3 hours. Slowly but led to a lot of water over time
more symptoms could be : 1-extensive smog in exhaust 2-coolant level decrease (sometimes you may hear water flow in car cabin specially at ~3000 RPM "when engine is cool") 3-increase engine oil amount 4-uneven engine idling (after engine is cooled - water leaks in engine and makes problems for spark plugs - it wont show when engine is hot) ignoring bad gasket may cause Subsequent problems for your car engine and increase costs !!!
that explain why i could hear water moving inside the cabin and my coolant was low and lots of misfiring after starting the vehicle. Thanks for your comment!!
If you drive your car on short hops, that can make the fill plug milky as well. Nothing wrong, just doesn't run long enough to evaporate normal condensation.
It's not me it's my neighbor hahaha, he's got a 96 Buick with 60k and a sparkplug separated and idk it's weird everything on the car looks perfect, expect small rust on the ignition coils
Test 1: "Mayonnaise" as its often called, or milky sludge, can occur when a vehicle is driven short distances. The vehicle may not be heating up the oil long enough to burn off natural condensation in the engine. As heat rises, the water vapour will stick to the oil cap and form an emulsion with the oil. You can wipe this goo off with a paper towel or lint free cloth. This condition can be prevented by either taking a long journey once every week or two, or by letting the car idle so it can come up to temperature and burn off this residual condensate. If you get this mayonnaise even after frequent long journeys then the head gasket might be bad. Test 2: If easy and safe to do so on your gasoline vehicle you can remove the fuel pump fuse and let the vehicle run out of fuel, restart the vehicle. When the vehicle is unable to run, you can now remove the spark plugs. Hold a printer page or similar closely over the spark plug hole and have another person crank the engine for a few seconds. If you observe any residue on the page, smell the page to see if its gasoline, if not it will most likely be water from the cooling system. You can add red (or other color) dye to the cooling system to further validate this, if the water on the page is red for example it's a guaranteed sign coolant is entering the combustion chamber. Test 3: When the engine is cool, there should be no bubbles in the radiator or expansion tank. If you see bubbles, combustion gasses are entering the cooling system. In this instance, you car will often present as an overheat condition. If you remove the radiator cap when the engine is at operating temperature (Never do this) the coolant will boil naturally. The radiator cap pressurises the cooling system to prevent the water from boiling. Test 4: As explained. However, in the case of diesel vehicles the solution will turn green indicating a bad head gasket. Test 5: A compression test will tell you if the compression is low, but not why its low. It can be low due to worn rings, bad head gasket, cracked block or head, warped block/head, or valve seat issues. A leak down test will tell you how much air is leaking from the cylinder, and where its leaking to; which is the important thing to know. Test 6: As explained. Test 7: If you checked all of the above and your vehicle is still showing overheat on the instrument cluster, check your temperature sensor and thermostat. A thermostat can stick closed which will cause engine overheating, and over time cause the head gasket to fail. Test 7: If you diagnose a bad head gasket its very important that you discover why the head gasket failed, if you just throw a new head gasket in and fail to rectify a crack in the head for example, you may blow the new head gasket in a matter of days.
Yes, I would say anything less than a 30 minute journey to be short. Considering it will take something like 4 minutes for the engine to come up to normal operating temperature. This means that your car only has 8 minutes or less to try and boil off the condensation. If 8 minutes isn't enough then you have more condensation accumulating than you can burn off and therefore get the mayonnaise forming. To combat this you can leave the car idling outside your house for 30 minutes or so once or twice a week if you have a lot of water in the oil. If its not so bad you could start the car in the morning, go back inside to finish breakfast, and by the time you're done the car will be boiling off the excess water on the way to work. Do this for one or two weeks and you should be goo free for another few weeks/months. You should also note the temperate of your location, and more importantly the dew point. *The dew point will determine how quickly the water droplets form inside the engine*. If you are often exceeding the dew point, then you will need to let the engine come up to temperature for extended periods of time. Otherwise the 30min idle once a week should do just fine. I hope this helps.
I have a 4.6 liter v8 and i have maybe like one water drop worth of this wite gunk on my oil cap... is this a sign of a potentially small break or not? I bough the car (I am 18 with 2 friends that are car mechanics) and i fuc*ed up... this mustang 2002 was upsidedown... (my friends checked it and nothing was visible only when i took off the cover i saw signs of straightening the roof very well made actually) So returning to the gasket is it broken or not (no smoke only this white gunk in a very very very small quantity) and I have an ignition coil screwed (one cylinder is not working (replace coming from the US) )
Also another way to tell your car's got a possible blown head gasket is you are not getting any heat. Since your cooling system is pressurized any loss of it will cause you to get no heat. Though it could be a clogged heater core or not enough coolant as well. Make sure to rule them out.
Yep that what we have. Radiator hose blew. Son drove it for maybe a minute to stop safely. After we replace the hose and refilling reservoir, coolant flows out exhaust pipe.
I would add to the compression test.... If you also notice a discrepancy between adjacent cylinders in excess of 20 psi, I would consider that vehicle as having a blown Head or may need a Head replacement soon.
My radiator overflow is always empty. I don't have any leaks on the ground. My car smokes some under the hood when you reve up the engine. Idk if it's oil or antifreeze I smell. I just bought this car in April. I dont drive it much but one shop told me it was a blown head gasket. After about 3 weeks of driving it it burned about 2 qts oil. My radiator was about 1/pitcher water low. One machanic came to my house and couldn't tell what was wrong.. but he made him a quick 20.00 smh!!
Yes Barbara your smelling both because they are mixing together and thats a sure sign of a blown head gasket the gasket is supposed to stop the fluids from mixing it will cause it to smoke a lot and overheat thats why you can't see a leak because their just mixing! I only know some things about cars from a long relationship with a mechanic!
That's what mine is doing now... constantly filling with 50/50 coolant (like twice a week), but no leaks on the ground or just a few drips here and there. I've got a mechanic coming by today 🤦🏽♀️. We have a Chrysler 200. I hate this car 😂
@@mstoi38sounds like the coolant is leaking to the exhaust side. In my case, i had a avenger. The coolant was burning up before I could see any indication of a leak. I hope you got it figured out. Next vehicle get a Toyota, save yourself the headaches 👍
@lozo4745 My dad always said "buy foreign," and he worked at USX 🤦🏽♀️🤣. Come to find out... my head gasket is blown. It was a crack. Thus, no smoke from the tailpipe at the time.
1 remove spark plugs from all cylinders turn the engine over if it blows out coolant you have a bad head gasket 2 remove all the coolant from the engine but don't run it longer than 2 minutes to be safe. the coolant will cause the spark plugs to not fire when it gets fuel because coolant doesn't ignite
U can also do it with the car powered off by checking the voltage of the cylinder using a volt meter and connect the positive end of the voltmeter to the negative battery terminal
I wish to say thank you I have a vehicle that I'm working on and trying to determine exactly which cylinder has the bypass blown head gasket it is a V8 so I'm going to exactly what you did and try to determine which cylinder it is because it is a V8 so hopefully I've only got to change one side of the head gaskets not both head gaskets so your video it's been very informative thank you for taking the time to make such a great video and you have possibly save me an extreme that time and money thank you
Might consider new head gaskets for both banks, one new one old and you could create an imbalance in the engine especially if you’re milling the cylinder head, happy torquing:)
Josh King I have a very minor coolant leak, but I bought my car private sale, when I had to change the cats I could drive on most roads but I couldn’t get the car over 40 without putting it in sport and changing the gears myself, I wouldn’t recommend driving the car, you’ll risk blowing your motor. i just changed my radiator hose because it was the size of a baseball.
Josh King my radiator water is bubbling out badly when cap is off.... but van is driving perfectly other than loosing water in radiator. Wonder if that always means a blown head gasket or hopefully something else.
@@samrichards8251 i recently had that problem with my 03 Seville,put a new radiator,heater core,water pump and thermostat in only to find out that a small bottle of k seal would've save me alot of money
In an old audi a4 we have cylinders 2 and 3 are misfiring and there's a coolant leak. This video makes so much sense now, goes to show how cool the internet is too
I used a bottle of Steel Seal to fix my head gasket, drained the coolant, removed the thermostat, flushed the cooling system really good, Then use a radiator cleaner to clean the cooling system , Make sure to flush out all the cleaner 100%, When engine is 100% cold add steel seal with distilled water, turn heater on high & let idle for 30 mins with the radiator cap off........Let it cool for 1 hour the let idle again for 30 mins with the radiator cap on...........next morning let it idle for another 30 mins then removed all water from the system to let the steel seal cure by air contact for 24 hours, Replace the thermostat, fill with coolant and your good to go. Mine has been running perfect for 70k miles now as i use the car for uber & lyft, Only cost me about $120 total.
I think that is the product we used on my buddies 2007 335i (twin turbos pushing 15psi). Comes in three bottles...1 flush. 2 ceramic block and head sealer. 3 coolant system stop leak addictive. Followed directions and no more steam shooting from the side of his engine. Still good 3 years later as far as I know. Great product.
Head Gasket blowed in my Car about a month ago and first i thought that i can fix it for myself cos im not a expert for fixing cars n i didnt know how damn huge operation it really is to change Head Gasket but after i saw a video where some dude fix HG in same car than i got,i let a local garage to do it cos with my repairing skills,i would make even more damage 😎 The Car is fixed now and it wasnt cheap ffs but no need to buy a new car so all good 👍 Sry for a crappy English ✌
My car has been over heating for the last few months and my mechanic said that the head casket had a crack in it. I didn't have the money to get it repaired so kept driving it. It did keep over heating but not every time I drove it. So about a week ago I was in an accident(not my fault) and it got sent to the repairers. I told them about the problem to see if they could fix it. In the end they said in was the coolant line that was faulty so they repaired it. Only had my car a day now but it drives much better and hasn't overheated yet. Do you really think my head gasket has a crack in it? Was my old mechanic just saying it was a head gasket to make some more money? They were going to charge me 4K to fix it. We also checked if the oil was milky and it looks just like oil. No milkiness
Hello there, nice video, basically i have 2013 Range (non supercharge. Since, Past two months i noticed that the coolant goes low but the engine does not heat up, this happened several times and i went to a local mechanic where i regularly go and got the radiator replaced. They did pressure test twice, no signs of leak. But still the issue persisted. I used to refill the coolant every week or so. I believe due to this the starter motor had gone bad(as i assume the engine got bit hard to turn on by itself) Now the vehicle has stopped starting. There are no sign of any leaks whatsoever. The radiator seems to go low only while running. My mechanic checked the starter motor, replaced the battery, replaced twice the fuse (on battery) yet no luck. Previously (in between this issue) i had got the oil and spark plugs changed. Now i can see some sort of milkshake type texture under the oil cap. I had re assessed with another mechanic who builds RR engines, he mentioned that this issue could be from the three coolers and not necessarily a head gasket failure. Additional information: There are no sign of over heating. I had noticed once, that from one of the AC vents, there is smoke coming. This comes only from vent and then goes. This happened about 10 times in past 2 months Current update: I just had the radiator coolant refilled up , without driving, i noticed that the coolant has gone low!.. Any expert advices will be helpful
What about engine power? The vehicle idles indefinitely. If you rev it, it dogs out. If you drive it, it has no pulling power on hills. It blows white vapor when first started; most of the white vapor goes away after about 5 minutes, but there is still a small amount of vapor, even 1/2 hour later.
Yep due to quality of metal used today in the manufacturing industry metal fatigue occurs often .That oil cooler has to handle high oil pressure getting pump through it
Hi. Thank you for the video. I have a 2008 Accord with 74k miles. The oil cap has a little milky oil. I checked the dipstick it's clean. I cleaned the oil cap and drove for 6 miles. I then checked the oil cap again and there was moister. I'm not losing any coolent. The car is not over heating. I never did a coolent flush on the vehicle.
Not always an indicator unless it is a considerable amount. Harmless condensation can build up in the exhaust system and then look like steam so it can be confusing. Thanks for watching!
Test 1: if you run e85, this is pretty normal. As alcohol attracts water like a magnet. Just make sure you burn it off since this can degrade your oil over time. To do this just do some longer rides, 20-30min at least once a week.
i have heard that:oil filling cap can be a test method that when be open if the valve ring is leaking there should be air blowing out side from engine>>>Is that right??
If I read your comment right you’re referring to blow by not blown head gasket. Blow by is caused from excessive compression in the cylinders not blown head gaskets.
I took the spark plugs out, filled up the overflow tank, and cranked the engine. As it spun over I looked through the space between the hood and the body. I could see a stream of water shooting out the number 3 cylinder! I put the plugs back in, closed the hood, and called AAA. I was about 15 miles from home and didn't have enough water to get back... It was a Friday and I had a head gasket. It was torn down, gasket replaced, put back together, and running by Sunday! That was years ago... ☹️
2008 impala 3.5 NEVER overheats, but coolant inside the reservoir boils to the point it steams a lot (giving the overheating impression) but steams only from reservoir and at times it spills over. Going to give these tests a try Thx
On my car the coolant in the radiator doesn't bubble until I turn off the car. But pretty sure it has a blown head gasket. The car is almost as old as I am and I'm 39.
Start the vehicle, remove radiator cap, rev up the engine in neutral gear, coolant should pour out the radiator filler cap, head gasket is blown, cylinder head is warped
the heat matrix leaks water when i put my heater on had some advice and was told also could mean head gasket on it's way out any info on this would be great as im not car minded
My car did not have much white on the oil cap. They did many tests. Turns out some oil valve seals were bad but they were not sure that was the problem but they did the work 4 of them were leaking.. They said engine was not heating very well. New thermostat fixed that. Pressure test turned up nothing. Car runs great.. Also they said drive it more Florida has so much moist air if you don't drive far and heat up the engine you will get this also. In Florida intakes bring in lots of water.
Not a bad video iv been wanting to make a video on blown head gasket tests. lol hopefully I don't have to XD I hope my channel gets a big as y'alls ,keep it up!
+2CarPros just changed my thermostat housing car drove about 10munutes heavy white smoke exited exhaust I cut it off and now it makes a single clunk noise and won't start any suggestions?
My coolant reservoir doesn't hold the anti-freeze content. I ignored it for years and never had any issues with it being empty. The vehicle never over heated. When I did put anti-freeze in the reservoir I smelled the light burn off. Question: If I had a head gasket (wouldn't any the spark plugs eventually begin to Fail because the coolant was being burned off, and there no evidence of any Oil contaminants (milky sludge)? Firestone manager says he has to charge me 70 dollars just to see if I have a head gasket issue...because they have to use several computer tests. Obviously, don't go to Firestone.
I have pressure and bubbles in my coolant reservoir but i have no goop on the caps and i have no bubbles in my radiator when the cars running is it possible my things are still blown?
This is exactly what happened to me, it probably overheated and blew the gasket open. So while it’s not completely busted it still needs fixed! It’ll keep overheating if not fixed
Not entirely true.. if the car only goes under 15min trips mostly. Then it never heats up enough to evaporate it off. In the colder north climates it’s a known thing. But yes it could be an indicator depending on the severity of it
Went to mechanic as noticed smoke from engine also when I open oil cap I can see smoke .. he said one of the possible reasons are motor gone bad or head gasket blown out 😢
This is exactly how I figured out im dealing with a blown head gasket for my 08 titan. *note* when you're consistently refilling your radiator and there's not leakage... check your exhust pipe.. if steam or water is coming out = blown gasket.
Guess I’m learning how to check spark plugs since I don’t have the other symptoms. It is running like it’s missing a spark plug, it’s got fuel starvation and no power, dies when I try to move it.
Had white cloud coming from my exhaust, had a cracked leaking radiator, I was loosing coolant. Got the radiator replaced & now only thin smoke for about 5 to 7 min after startup. Could I have a small head gasket fracture?
I have a similar problem. Had a bad radiator leaking. Used stop leak to fix the problem for a while but the car ran hot smoking about 4 times. Had radiator replaced. And now car seems to be running fine with the occasional thin poof of smoke. On startup and while idling. Not really bad but visible. Don't know if it's a possible small head gasket fracture or one valves like you had said in this comment. I went and bought some head gasket repair liquid. But haven't put it in yet because I'm not sure if that's the problem or not. What do you suggest?
So I have been having some problems lately with overheating. My truck was going up to 260 within 5 minutes. So I parked it and we replaced the radiator, coolant temp sensor, egr valve, thermostat and bled the system numerous times and it fixed it to an extent. The gauge will show anything from 1/4-3/4 but it never goes up to 260. The heat works occasionally and the exhaust at times will blow white smoke and then it will stop
You go shopping or go to a shop. I like to do my own work, so I just buy. Most of these tools will last a life time. Never know when you might use them again.
Great video man, I did get a misfire in cylinder 1&6 ? And I got some white puff smoke lasts for 3-4sec upon start up while car sets for a short of time ? Is that head gasket ? Or something else ?
My GFs step dad sold me his truck. I should've checked TH-cam and gotten a manual first. Within a few months the gasket blew and now I'm out of a car again.
I know this is a very old video but maybe I will get lucky and some one will answer my question, which is; how can I tell if the small coolant leak is between the intake to the head and not from the head to the engine block? I found moisture on the plenum when I took it off for cleaning, maintenance. From a 2000 Accord v6 God bless.
I have old Dodge pick up and it has an entirely new cooling system. New radiator, hoses, water pump, and thermostat. It’s still wanting to overheat. There are no bubbles, the coolant looks perfect, no milky residue or sludge. There is a puff of white smoke when I first start it, but that’s it. Any suggestions?
Could be a blown head gasket or there could be a air bubble in the back of the block. Try jacking up the rear end and then the front end and see if you have a air bubble come out. Thanks for watching!
I have a 2006 kia Sedona i had a blown head gaster i put blue devils sealer and my van ran great i know i put over 1500 miles but what happen my fans stop working and i did not fix it a my van was fine as long i be drive it but when i stop standing my van start running hot other than that i did not have know problem with blue devils but after that my van had cut off so now it want start but i gave car shield and they trying say my problem is pretty insistent on the first time but my van was running fine i t probably from that fan from stop working..but i give blue devils A so thankful.. Fr Emma..
Hay, I pulled my cylinder head off and found a gap/burn in the gasket between the cylinders. No water in oils or oil in coolant. When I looked down the cylinders and saw no cross hatching, do I need to hone them? Can I hone without taking out the pistons? I wasn't burning oil. Thanks
Best and the most accurate way is spray spirts of starting fluid around the the main manifold and heads it the engine rubs up you have a bad head gasket or bad manifold gasget old school is always the best way
On my 2003 civic the temperature only went high one time, every time I open he radiator and check the coolant level it’s always a little low. The fans are coming on. Not sure if I have a blown head gasket or if I just have a coolant leak somewhere.
I have the same issue on my 2003 Civic with 150k miles. Is suspect it's a head gasket since there's a black ring in the radiator, I smell exhaust gas in the radiator after driving, and some coolant is missing. I replaced the thermostat, cap, and pressure tested. No loss of pressure or leaks, and fans are running fine. I thought I would lose pressure if it was a head gasket, but maybe I should remove the spark plugs and pressure test again.
I have a 2007 Silverado 4.8 that just rolled over 300,000 miles. I had cranked the engine to check if brakes needed bleeding. A couple of weeks ago I had replaced the connectors and lines that go to the fire wall for the heater core. I noticed that it was leaking. It appeared to be at the connector on the hose coming out of the engine going to the firewall. I had reused the original clamps. I turned it off and was going to replace the claps with new screw tighten type clamps. When I turned it off, it made a kind of dieseling sound and white smoke came out of the exhaust. I cranked it back up and it is smoking badly, white smoke. I ran it less than a minute and shut it off. I waited a few minutes and cranked it back up, still lots of white smoke. I ran it maybe a minute total. It idles fine and revs fine. Oil doesn't look milky at all and neither does antifreeze in the overflow tank. Could this be anything else or am I looking at a gasket or cracked head? thanks.
@@ramiromeza5915 Yeah, I had changed my oil at the same time. I had changed my oil and I had accidently got synthetic oil. O'Reilly's had rearranged their oil display and I just went in and grabbed oil from the same place I had been grabbing oil for all three of our trucks for years. Totally my fault. I changed it again replacing it with the same conventional oil that I had been using. Ran it about 60 miles and changed it again, Using 6 ounces of Sea Foam in the oil both times. hasn't smoked since. about to hit 350,000 miles.
I completely drained my coolant and oil. #1 there is no milky stuff on the oil cap. #2 The coolant looked perfect. #3 The oil looked Normal. On another video the oil looked horrible milky or almost creamy... ugh.,.. #4 No bubbles when removing radiator cap.' #5 Engine runs perfect and idles perfectly. My power is perfect and My gas mileage is Great... but there is a slight smell of oil or gas in the coolant overflow container. Fck it! I'm buying another engine! hahahaha... It's good for now but better safe than not. Peace!
No but after a while If you lose all your coolant and you start to overheat , yes, or if the coolant gets your spark plugs dirty, it will cause a misfire check engine code, eventually you will see smoke in your exhaust or and the car won run normal
my 93 mustang gt over heats when im stuck in traffic on a hot day or if left on idle for a while. a little bit of white smoke does come out the tailpipe but nothing crazy. the only way it wont over heat is if the car is actually moving or if its a cold day. ideas on what it might be? im leaning more towards the head gasket theory but not 100% sure.
So if i see the milky substance swirling around in my radiator and some of it in my coolant reservoir but NOT in my engine oil filler hole does that mean it's not a blown or cracked head gasket?
If you remove the overflow tank cap when cold and run the engine do you not have to wait until the coolant is warm enough to open the thermostat to see the air bubbles? If it opens will the overflow tank not start overflowing coolant at that point? Thx
I checked my oil today, which I do monthly, and my oil was milky… not heavy but it was noticeable!! It’s a 2012 mercedes c350 and the coolant level is normal as it was when I last checked it. Clean and clear. Car on and I see 0 bubbles.. no smoke out of the exhaust whatsoever. No misfires. No check engine light. No oil leaks either. We did have heavy rain a couple weeks ago, but idk how water could enter the engine…. Any idea?
Older Mercs always have leaks, if it leaks out then water can leak in. Probably where your slight milkiness came from. OR its a very small head gasket leak. Thanks for watching!
I have a 1991 Nissan hardbody pickup. My water pump went out, and I drove to a safe location where I could call a tow-truck. Here's my question When a water pump is being replaced, would a blown head gasket be noticeable ? Thanks
Christie No usually not at the waterpump will you anything weird or unusual. Where you should check is by opening the oil filler cap. If the head gasket was just blown at that very moment you probably can't tell and everything will look normal. If the head gasket has been leaking or blown for some time then you should see foam slimy frothy brown oily liquid when you open your oil filler cap. That is the motor oil mixing with your coolant.
If the car has a head gasket problem (low compression, misfire) but the oil does not show any signs of coolant in the engine, would it be okay to buy the car to drive after repairing the head gasket?
What would/could be the cause of an LT1 over heating when parking? The car starts overheating fast when I'm slowly manuvering (Few feet forward, few feet back etc) into a parking space Car is fine at all other times Water pump, thermostat, and coolant are all about 1 year old I bled the system Fuses and box LOOKED ok Just put on a new ac delco rad cap Unplugged the WP to test the fans and the drivers side works but NOT the passenger side Neither the AC or the heat hasn't worked for over a year btw
TU & subscribed. Questions: my 98 Sonoma 2.2L with 176k is having the head done (blown gasket....previously paid ($1,350) to a shop mechanic 1 month ago who ripped me off not doing anything to the warped head, amongst other faults. Now the head is being pressure tested, milled and valve job for $350 by professionals with a guarantee. I think it now wise to replace the coolant & oil pumps even though no prior indication of faults. I plan to replace the piston rings from the top. Doable? Would you suggest the timing chain as well? I ask about the chain partly because I see some kits that have the two pumps and chain together implying this is normally done together. Is the Cloyes that does away with the tensioners a better choice than OEM? I am poor and unemployed just trying to be proactive. Am I going too far? Thanx, Mark ps...I prefer to keep this truck, other than the current problems it is in perfect condition.
The chain usually doesn’t need to get changed. The belt usually needs to get done and while you’re in there it is an extra 10 minutes to do the pumps. This is probably a leftover from the belt kits, where guys are just trying to sell a bit more and do a kit. Unless there is something wrong with your timing or it is damaged in some way, you likely do jot need to do the chain.
Okay there's no milky residue in oil or on oil cap, there's no bubbles in radiator, but two spark plugs did appear to look like they had rusted a bit. There is so many other things happening with this vehicle and I was hoping that some other problem could possibly make spark plugs look that way. Car runs fine, it randomly runs hot if idling, although it doesn't go any high hot but needs some water every time. Thermostat was put on thinking that would help, I noticed the top hose running from radiator to thermostat was very hard and hot...IDK what to do
Guys Test Number 3 is Enough for Gasket checking if the bubbles are coming out or blowing.. Your gasket is over.. Replace it as soon as possible.. otherwise.. wait for the engine to get blown!
My car is a 3 cylinder. Has no mayo, some coolant has been used over maybe 2 or 3 months but not huge amounts. Did a compression test and cylinder 1 and 3 were 185 but cylinder 2 was 150. I can also hear an audible whistle between 3 to 4.5k revs. sounds like a exhaust leak but it is not as I've had a new one fitted and took it to the garage 3 times as I was not sure. Cylinder 2 also misfires is left at idle for 10 minutes. I've taken my car to 4 garages and one specialist who couldn't find an issue. What could be wrong?
My 07 Versa became overheated... took it to the mech. Pour some liquid.. it was leaking at the bottom. Fix the hose, n now the ignition coil was filled with oil... it struggled a lil bit to start the car. Put a new gasket n I.coils. now it runs fine, but it feels a lil weird when driving it.. like if not fixed all the way. What could be the final verdict? Is the car done?
i changed the spark plugs the spark plug wires the ignition coils the intake manifold and the car is still shaking so i went to a mechanic and he did a leak down test and a compression test. then he said two of the cylinders have low compression and that's what's causing the car to shake, so he said i have to do a head job. i did a head job already on this car back in 2014 and it's 2021 so 7 years and i have to do another one
My 2000 Sts blew thick white smoke...lost power....but no milky goo under cap... Someone told me it could be somethin else other than gasket since oil not milky.. Exhaust has sweet smell to it...
Some of these are dependent on the spot where the void is present right? Stupid question but ive had an open space in a gasket before not present with no discolored exhuast, or mixing of fluids. Only accelerating sluggishness and obvious misfires
I have an 06 charger rt, new water pump, new coolant reservoir, new thermostat. No leaks, the fans come on when they're supposed to, yet my coolant still boils over and runs hot?
Hi, my Chevrolet Optra 2010 engine overheating. I noticed the coolant level was low and filled it up to MAX and drove around 3 days. Air conditioning was on while I was driving it, suddenly became so hot in the cabin. I stopped the car and the engine went-off on it's own. The engine couldn't be ignited there after. I took to mechanic and he said, the cause was due to engine head-gasket. He changed the head-gasket but the problem still persist, engine still overheats within a 5 minutes and gauge rises from 1/4. Mechanic said, now only engine fully has to be changed. Any suggestion please? I also noticed leakage from the coolant cap, replaced it, then seemed fine. Please share some information. I really appreciate your feedback. Thank you very much.

Big indicators, milky substance like shown, and the antifreeze overflow container level rises with water and dirty sludgy water. If running long enough water inside gets hot and bubbles from air flowing in. Can cause your container to also crack. Great video!

My mom just texted me about a blown head gasket... SMH
No blown head gasket on my 6.0
A very easy way to tell whether you have a blown gasket is to just remove the oil. If water falls out first then the gasket is blown. Because oil sits on top of water.
That doesnt confirm headgasket is blown, only that coolant is making its way into the oil. Could be from the oil cooler leaking.
Oh, sure. It's very easy to drain the oil and buy more oil to put back in. Much easier than using the proper tester or observing the radiator cap opening for bubbles as described in this video.
Fkn donut.🙄
Or fuel leaking into coolant there are many different things that can differ from where the head gasket is damaged
Lots of white smoke and collent is being evaporated
Is a gasket repair extremely expensive
I did all those tests and could not find my blown gasket - but the following test showed the problem - remove radiator cap and bring level into view - bring a cylinder u want to test to top dead center on ignition stroke [both valves closed] put compression test hose or extension [without check valve in it] into spark plug hole - attach shop air to supply shop air at 100 psi into cylinder on a warm engine - observe coolant in radiator for rise in level or bubbles.
Good experience, many thanks for sharing your experiment, i have the same problem with car. could share more, i am a automotive technical service at college so i love to hear from you. thank you so much,
Good stuff. Here's another tip, it happened to me once:
I pressurized the cooling system, looking for any water leaks. Well, if your equipment is working well (no air leaks out the pump itself or via the radiator filler neck) the system should maintain a steady pressure reading at about 12 psi (I believe. Sometimes I only fill to 7) if pressure drops within 5 minutes, I look for signs of water, on the ground, around the engine. Well, I didn't see any water anywhere..which lead me to believe that water was being lost inside the motor due to a blown head gasket.
What kins of color was this water? Me and my buddies audi a4 has oil in the coolant reservoir. We were working on it today and it was dripping a white opaque water below the engine for about 3 hours. Slowly but led to a lot of water over time
@@logansimpson804 Sounds like he had a blown head gasket from an oil port to a water port. What did he ever do with it?
@@RC-Heli835 ended up parting it out. Took the heads off and visually were fine but 90% sure it was gaskets
more symptoms could be :
1-extensive smog in exhaust
2-coolant level decrease (sometimes you may hear water flow in car cabin specially at ~3000 RPM "when engine is cool")
3-increase engine oil amount
4-uneven engine idling (after engine is cooled - water leaks in engine and makes problems for spark plugs - it wont show when engine is hot)
ignoring bad gasket may cause Subsequent problems for your car engine and increase costs !!!
I have 2 (very very fast) and 3... that settles it, right?
that explain why i could hear water moving inside the cabin and my coolant was low and lots of misfiring after starting the vehicle. Thanks for your comment!!
If you drive your car on short hops, that can make the fill plug milky as well. Nothing wrong, just doesn't run long enough to evaporate normal condensation.
Thank you
What happens if you car was sitting for 3 months in cold weather with its dirty oil. Now it’s milky??
What happened if you don’t drive your car for 3 days and you get white stuff on oil cap

2.5 TDi Touareg.. it will be a nightmare working on
It's not me it's my neighbor hahaha, he's got a 96 Buick with 60k and a sparkplug separated and idk it's weird everything on the car looks perfect, expect small rust on the ignition coils
Test 1: "Mayonnaise" as its often called, or milky sludge, can occur when a vehicle is driven short distances. The vehicle may not be heating up the oil long enough to burn off natural condensation in the engine. As heat rises, the water vapour will stick to the oil cap and form an emulsion with the oil. You can wipe this goo off with a paper towel or lint free cloth. This condition can be prevented by either taking a long journey once every week or two, or by letting the car idle so it can come up to temperature and burn off this residual condensate. If you get this mayonnaise even after frequent long journeys then the head gasket might be bad.
Test 2: If easy and safe to do so on your gasoline vehicle you can remove the fuel pump fuse and let the vehicle run out of fuel, restart the vehicle. When the vehicle is unable to run, you can now remove the spark plugs. Hold a printer page or similar closely over the spark plug hole and have another person crank the engine for a few seconds. If you observe any residue on the page, smell the page to see if its gasoline, if not it will most likely be water from the cooling system. You can add red (or other color) dye to the cooling system to further validate this, if the water on the page is red for example it's a guaranteed sign coolant is entering the combustion chamber.
Test 3: When the engine is cool, there should be no bubbles in the radiator or expansion tank. If you see bubbles, combustion gasses are entering the cooling system. In this instance, you car will often present as an overheat condition. If you remove the radiator cap when the engine is at operating temperature (Never do this) the coolant will boil naturally. The radiator cap pressurises the cooling system to prevent the water from boiling.
Test 4: As explained. However, in the case of diesel vehicles the solution will turn green indicating a bad head gasket.
Test 5: A compression test will tell you if the compression is low, but not why its low. It can be low due to worn rings, bad head gasket, cracked block or head, warped block/head, or valve seat issues. A leak down test will tell you how much air is leaking from the cylinder, and where its leaking to; which is the important thing to know.
Test 6: As explained.
Test 7: If you checked all of the above and your vehicle is still showing overheat on the instrument cluster, check your temperature sensor and thermostat. A thermostat can stick closed which will cause engine overheating, and over time cause the head gasket to fail.
Test 7: If you diagnose a bad head gasket its very important that you discover why the head gasket failed, if you just throw a new head gasket in and fail to rectify a crack in the head for example, you may blow the new head gasket in a matter of days.
How long is a "short" distance? When I drive to work it's about 5 miles and about a 12 minute ride. Is that short enough to show then?
Yes, I would say anything less than a 30 minute journey to be short. Considering it will take something like 4 minutes for the engine to come up to normal operating temperature. This means that your car only has 8 minutes or less to try and boil off the condensation. If 8 minutes isn't enough then you have more condensation accumulating than you can burn off and therefore get the mayonnaise forming.
To combat this you can leave the car idling outside your house for 30 minutes or so once or twice a week if you have a lot of water in the oil. If its not so bad you could start the car in the morning, go back inside to finish breakfast, and by the time you're done the car will be boiling off the excess water on the way to work. Do this for one or two weeks and you should be goo free for another few weeks/months.
You should also note the temperate of your location, and more importantly the dew point. *The dew point will determine how quickly the water droplets form inside the engine*. If you are often exceeding the dew point, then you will need to let the engine come up to temperature for extended periods of time. Otherwise the 30min idle once a week should do just fine.
I hope this helps.
I have a 4.6 liter v8 and i have maybe like one water drop worth of this wite gunk on my oil cap... is this a sign of a potentially small break or not? I bough the car (I am 18 with 2 friends that are car mechanics) and i fuc*ed up... this mustang 2002 was upsidedown... (my friends checked it and nothing was visible only when i took off the cover i saw signs of straightening the roof very well made actually)
So returning to the gasket is it broken or not (no smoke only this white gunk in a very very very small quantity) and I have an ignition coil screwed (one cylinder is not working (replace coming from the US) )

Also another way to tell your car's got a possible blown head gasket is you are not getting any heat. Since your cooling system is pressurized any loss of it will cause you to get no heat. Though it could be a clogged heater core or not enough coolant as well. Make sure to rule them out.
Blower motor can also cause no heat.
Or ur just low on coolant
Also check radiator oil cooler
@@codyzent6471 well that's a no brainer!
Also if your heat isn't working it could also be a sign of a bad serpentine belt.
Massive amount of water shooting out the tail pipe is a great indicator
Yep that what we have. Radiator hose blew. Son drove it for maybe a minute to stop safely. After we replace the hose and refilling reservoir, coolant flows out exhaust pipe.
I would add to the compression test.... If you also notice a discrepancy between adjacent cylinders in excess of 20 psi, I would consider that vehicle as having a blown Head or may need a Head replacement soon.
Test number 1, you consistently have to refill the radiator overflow but no fluids are under the vehicle.
My radiator overflow is always empty. I don't have any leaks on the ground. My car smokes some under the hood when you reve up the engine. Idk if it's oil or antifreeze I smell. I just bought this car in April. I dont drive it much but one shop told me it was a blown head gasket. After about 3 weeks of driving it it burned about 2 qts oil. My radiator was about 1/pitcher water low.
One machanic came to my house and couldn't tell what was wrong.. but he made him a quick 20.00 smh!!
Yes Barbara your smelling both because they are mixing together and thats a sure sign of a blown head gasket the gasket is supposed to stop the fluids from mixing it will cause it to smoke a lot and overheat thats why you can't see a leak because their just mixing! I only know some things about cars from a long relationship with a mechanic!
That's what mine is doing now... constantly filling with 50/50 coolant (like twice a week), but no leaks on the ground or just a few drips here and there. I've got a mechanic coming by today 🤦🏽♀️. We have a Chrysler 200. I hate this car 😂
@@mstoi38sounds like the coolant is leaking to the exhaust side. In my case, i had a avenger. The coolant was burning up before I could see any indication of a leak. I hope you got it figured out. Next vehicle get a Toyota, save yourself the headaches 👍
@lozo4745 My dad always said "buy foreign," and he worked at USX 🤦🏽♀️🤣.
Come to find out... my head gasket is blown. It was a crack. Thus, no smoke from the tailpipe at the time.
1 remove spark plugs from all cylinders turn the engine over if it blows out coolant you have a bad head gasket
2 remove all the coolant from the engine but don't run it longer than 2 minutes to be safe. the coolant will cause the spark plugs to not fire when it gets fuel because coolant doesn't ignite
Super informative video.
Decent sounding dude.

Another way to test is to run the engine while having the radiator pressure gauge hooked up you will see a jumping if it is blown.
U can also do it with the car powered off by checking the voltage of the cylinder using a volt meter and connect the positive end of the voltmeter to the negative battery terminal

Might consider new head gaskets for both banks, one new one old and you could create an imbalance in the engine especially if you’re milling the cylinder head, happy torquing:)

Josh King I have a very minor coolant leak, but I bought my car private sale, when I had to change the cats I could drive on most roads but I couldn’t get the car over 40 without putting it in sport and changing the gears myself, I wouldn’t recommend driving the car, you’ll risk blowing your motor. i just changed my radiator hose because it was the size of a baseball.
Josh King my radiator water is bubbling out badly when cap is off.... but van is driving perfectly other than loosing water in radiator. Wonder if that always means a blown head gasket or hopefully something else.

My car has been over heating for the last few months and my mechanic said that the head casket had a crack in it. I didn't have the money to get it repaired so kept driving it. It did keep over heating but not every time I drove it. So about a week ago I was in an accident(not my fault) and it got sent to the repairers. I told them about the problem to see if they could fix it. In the end they said in was the coolant line that was faulty so they repaired it. Only had my car a day now but it drives much better and hasn't overheated yet. Do you really think my head gasket has a crack in it? Was my old mechanic just saying it was a head gasket to make some more money? They were going to charge me 4K to fix it. We also checked if the oil was milky and it looks just like oil. No milkiness

Hello there, nice video,
basically i have 2013 Range (non supercharge. Since, Past two months i noticed that the coolant goes low but the engine does not heat up, this happened several times and i went to a local mechanic where i regularly go and got the radiator replaced. They did pressure test twice, no signs of leak. But still the issue persisted. I used to refill the coolant every week or so. I believe due to this the starter motor had gone bad(as i assume the engine got bit hard to turn on by itself) Now the vehicle has stopped starting. There are no sign of any leaks whatsoever. The radiator seems to go low only while running.
My mechanic checked the starter motor, replaced the battery, replaced twice the fuse (on battery) yet no luck.
Previously (in between this issue) i had got the oil and spark plugs changed. Now i can see some sort of milkshake type texture under the oil cap.
I had re assessed with another mechanic who builds RR engines, he mentioned that this issue could be from the three coolers and not necessarily a head gasket failure.
Additional information:
There are no sign of over heating.
I had noticed once, that from one of the AC vents, there is smoke coming. This comes only from vent and then goes. This happened about 10 times in past 2 months
Current update:
I just had the radiator coolant refilled up , without driving, i noticed that the coolant has gone low!..
Any expert advices will be helpful
What about engine power? The vehicle idles indefinitely. If you rev it, it dogs out. If you drive it, it has no pulling power on hills. It blows white vapor when first started; most of the white vapor goes away after about 5 minutes, but there is still a small amount of vapor, even 1/2 hour later.

Hi. Thank you for the video. I have a 2008 Accord with 74k miles. The oil cap has a little milky oil. I checked the dipstick it's clean. I cleaned the oil cap and drove for 6 miles.

I noticed you didnt mention anything about white smoke exiting the exhaust which is a clear indicator of coolant in the combustion.
Not always an indicator unless it is a considerable amount. Harmless condensation can build up in the exhaust system and then look like steam so it can be confusing. Thanks for watching!

Test 1: if you run e85, this is pretty normal. As alcohol attracts water like a magnet. Just make sure you burn it off since this can degrade your oil over time. To do this just do some longer rides, 20-30min at least once a week.
Step 1: Is there smoke coming out from under your hood?
i have heard that:oil filling cap can be a test method that when be open if the valve ring is leaking there should be air blowing out side from engine>>>Is that right??
If I read your comment right you’re referring to blow by not blown head gasket. Blow by is caused from excessive compression in the cylinders not blown head gaskets.
I took the spark plugs out, filled up the overflow tank, and cranked the engine. As it spun over I looked through the space between the hood and the body. I could see a stream of water shooting out the number 3 cylinder! I put the plugs back in, closed the hood, and called AAA. I was about 15 miles from home and didn't have enough water to get back... It was a Friday and I had a head gasket. It was torn down, gasket replaced, put back together, and running by Sunday! That was years ago... ☹️
bubbleing in the radiator cap is good or bad?
Bad.
This man speaks the truth, unlike all the people down in the comment section that bring up the typical social media stereotypes.
When you check the coolant for bubbling can you do the same with checking the resovoir tank?
Yes if you don't have a radiator cap. Thanks for watching!
2008 impala 3.5
NEVER overheats, but coolant inside the reservoir boils to the point it steams a lot (giving the overheating impression) but steams only from reservoir and at times it spills over.
Going to give these tests a try
Thx
Thanks for watching!
Try a new rad cap also
On my car the coolant in the radiator doesn't bubble until I turn off the car. But pretty sure it has a blown head gasket. The car is almost as old as I am and I'm 39.
Start the vehicle, remove radiator cap, rev up the engine in neutral gear, coolant should pour out the radiator filler cap, head gasket is blown, cylinder head is warped
K Seal Is an engines coolant leak best friend, until it goes to the graveyard or hospital for major surgery 👍
the heat matrix leaks water when i put my heater on had some advice and was told also could mean head gasket on it's way out any info on this would be great as im not car minded
My car did not have much white on the oil cap. They did many tests. Turns out some oil valve seals were bad but they were not sure that was the problem but they did the work 4 of them were leaking.. They said engine was not heating very well. New thermostat fixed that. Pressure test turned up nothing. Car runs great.. Also they said drive it more Florida has so much moist air if you don't drive far and heat up the engine you will get this also. In Florida intakes bring in lots of water.
You should see a continuous stream of bubbles when the gasket is good or gasket is blown?
Blown, as these will be the exhaust gasses escaping through the coolant.
Not a bad video iv been wanting to make a video on blown head gasket tests.
lol hopefully I don't have to XD

+2CarPros just changed my thermostat housing car drove about 10munutes heavy white smoke exited exhaust I cut it off and now it makes a single clunk noise and won't start any suggestions?
My coolant reservoir doesn't hold the anti-freeze content. I ignored it for years and never had any issues with it being empty. The vehicle never over heated. When I did put anti-freeze in the reservoir I smelled the light burn off.
Question: If I had a head gasket (wouldn't any the spark plugs eventually begin to Fail because the coolant was being burned off, and there no evidence of any Oil contaminants (milky sludge)?
Firestone manager says he has to charge me 70 dollars just to see if I have a head gasket issue...because they have to use several computer tests. Obviously, don't go to Firestone.
I have pressure and bubbles in my coolant reservoir but i have no goop on the caps and i have no bubbles in my radiator when the cars running is it possible my things are still blown?
This is exactly what happened to me, it probably overheated and blew the gasket open. So while it’s not completely busted it still needs fixed! It’ll keep overheating if not fixed
So my vehicle has a milky sludge on the cap but that's about it. I never saw white smoke or anything from it.
Forgot the most easiest method,pull the oil dip stick.If there is oil mixed with antifreeze on it.It is a head gasket & oil is going into the oil pan.
Not entirely true.. if the car only goes under 15min trips mostly. Then it never heats up enough to evaporate it off. In the colder north climates it’s a known thing. But yes it could be an indicator depending on the severity of it
Went to mechanic as noticed smoke from engine also when I open oil cap I can see smoke .. he said one of the possible reasons are motor gone bad or head gasket blown out 😢

This is exactly how I figured out im dealing with a blown head gasket for my 08 titan. *note* when you're consistently refilling your radiator and there's not leakage... check your exhust pipe.. if steam or water is coming out = blown gasket.
Guess I’m learning how to check spark plugs since I don’t have the other symptoms. It is running like it’s missing a spark plug, it’s got fuel starvation and no power, dies when I try to move it.
Had white cloud coming from my exhaust, had a cracked leaking radiator, I was loosing coolant. Got the radiator replaced & now only thin smoke for about 5 to 7 min after startup. Could I have a small head gasket fracture?
Thin smoke on startup sounds like worn valves or valve stem seals.
I have a similar problem. Had a bad radiator leaking. Used stop leak to fix the problem for a while but the car ran hot smoking about 4 times. Had radiator replaced. And now car seems to be running fine with the occasional thin poof of smoke. On startup and while idling. Not really bad but visible. Don't know if it's a possible small head gasket fracture or one valves like you had said in this comment. I went and bought some head gasket repair liquid. But haven't put it in yet because I'm not sure if that's the problem or not. What do you suggest?
So I have been having some problems lately with overheating. My truck was going up to 260 within 5 minutes. So I parked it and we replaced the radiator, coolant temp sensor, egr valve, thermostat and bled the system numerous times and it fixed it to an extent. The gauge will show anything from 1/4-3/4 but it never goes up to 260. The heat works occasionally and the exhaust at times will blow white smoke and then it will stop
Okay so what's about the ordinary guy who doesn't have all these gadgets🥱
Go to a mechanic obviously
You go shopping or go to a shop. I like to do my own work, so I just buy. Most of these tools will last a life time. Never know when you might use them again.
You can rent the compression test and the exhaust gas test for free at Autozone, if you live in the states
The milky goo could be because of condensation as well. It depends how thick the "goo" is

I have a 2006 kia Sedona i had a blown head gaster i put blue devils sealer and my van ran great i know i put over 1500 miles but what happen my fans stop working and i did not fix it a my van was fine as long i be drive it but when i stop standing my van start running hot other than that i did not have know problem with blue devils but after that my van had cut off so now it want start but i gave car shield and they trying say my problem is pretty insistent on the first time but my van was running fine i t probably from that fan from stop working..but i give blue devils A so thankful.. Fr Emma..
Found this really helpful thanks.
Glad to hear it!
What about white smoke blowing out of the exhaust pipe...would that be a blown head gasket symptom?
Yep, that's a big symptom. Thanks for watching!
Hay, I pulled my cylinder head off and found a gap/burn in the gasket
between the cylinders. No water in oils or oil in coolant. When I looked down the cylinders and saw no cross
hatching, do I need to hone them? Can I hone without taking out the
pistons? I wasn't burning oil. Thanks
Best and the most accurate way is spray spirts of starting fluid around the the main manifold and heads it the engine rubs up you have a bad head gasket or bad manifold gasget old school is always the best way
On my 2003 civic the temperature only went high one time, every time I open he radiator and check the coolant level it’s always a little low. The fans are coming on. Not sure if I have a blown head gasket or if I just have a coolant leak somewhere.
I have the same issue on my 2003 Civic with 150k miles. Is suspect it's a head gasket since there's a black ring in the radiator, I smell exhaust gas in the radiator after driving, and some coolant is missing. I replaced the thermostat, cap, and pressure tested. No loss of pressure or leaks, and fans are running fine. I thought I would lose pressure if it was a head gasket, but maybe I should remove the spark plugs and pressure test again.
Buy the mitivac mv4560 pressure tester. It will find the leak if it's a hose or the radiator. Like 50$.
What about number seven white smoke coming from the exhaust?
I have a 2007 Silverado 4.8 that just rolled over 300,000 miles. I had cranked the engine to check if brakes needed bleeding. A couple of weeks ago I had replaced the connectors and lines that go to the fire wall for the heater core. I noticed that it was leaking. It appeared to be at the connector on the hose coming out of the engine going to the firewall. I had reused the original clamps. I turned it off and was going to replace the claps with new screw tighten type clamps. When I turned it off, it made a kind of dieseling sound and white smoke came out of the exhaust. I cranked it back up and it is smoking badly, white smoke. I ran it less than a minute and shut it off. I waited a few minutes and cranked it back up, still lots of white smoke. I ran it maybe a minute total. It idles fine and revs fine. Oil doesn't look milky at all and neither does antifreeze in the overflow tank. Could this be anything else or am I looking at a gasket or cracked head? thanks.
did u ever find out what it was? my 07 is having this problem
@@ramiromeza5915 Yeah, I had changed my oil at the same time. I had changed my oil and I had accidently got synthetic oil. O'Reilly's had rearranged their oil display and I just went in and grabbed oil from the same place I had been grabbing oil for all three of our trucks for years. Totally my fault. I changed it again replacing it with the same conventional oil that I had been using. Ran it about 60 miles and changed it again, Using 6 ounces of Sea Foam in the oil both times. hasn't smoked since. about to hit 350,000 miles.
I completely drained my coolant and oil.
#1 there is no milky stuff on the oil cap.
#2 The coolant looked perfect.
#3 The oil looked Normal.
On another video the oil looked horrible milky or almost creamy... ugh.,..
#4 No bubbles when removing radiator cap.'
#5 Engine runs perfect and idles perfectly.
My power is perfect and My gas mileage is Great... but there is a slight smell of oil or gas in the coolant
overflow container.
Fck it! I'm buying another engine! hahahaha... It's good for now but better safe than not. Peace!
Will a blown head gasket turn the check engine light on ?
Not directly, but it'll lead to problems that will.
Most likely o2 sensor
No but after a while If you lose all your coolant and you start to overheat , yes, or if the coolant gets your spark plugs dirty, it will cause a misfire check engine code, eventually you will see smoke in your exhaust or and the car won run normal
Hey pip thanks for the informative videos really helped, say hi to napoleon dynamite for me and uncle rico
Alright, thanks for watching!
Lmao
my 93 mustang gt over heats when im stuck in traffic on a hot day or if left on idle for a while. a little bit of white smoke does come out the tailpipe but nothing crazy. the only way it wont over heat is if the car is actually moving or if its a cold day. ideas on what it might be? im leaning more towards the head gasket theory but not 100% sure.
Cooling fan isn't kicking in, blockage in radiator, or thermostat may be stuck
exact same issue on an 87" Mercedes benz 260E ( 2.6L M103 inline 6)
So if i see the milky substance swirling around in my radiator and some of it in my coolant reservoir but NOT in my engine oil filler hole does that mean it's not a blown or cracked head gasket?
So the cap is clear of milky sludge? Perhaps the problem needs more time to develop in order for the sludge to turn milky
Exactly what’s going on with my car
If you remove the overflow tank cap when cold and run the engine do you not have to wait until the coolant is warm enough to open the thermostat to see the air bubbles? If it opens will the overflow tank not start overflowing coolant at that point? Thx
I checked my oil today, which I do monthly, and my oil was milky… not heavy but it was noticeable!! It’s a 2012 mercedes c350 and the coolant level is normal as it was when I last checked it. Clean and clear. Car on and I see 0 bubbles.. no smoke out of the exhaust whatsoever. No misfires. No check engine light. No oil leaks either. We did have heavy rain a couple weeks ago, but idk how water could enter the engine…. Any idea?
Older Mercs always have leaks, if it leaks out then water can leak in. Probably where your slight milkiness came from. OR its a very small head gasket leak. Thanks for watching!
Great quick video!
Thank you so much for watching!
Very informative video, thanks guys 👍
No problem 👍
I have a 1991 Nissan hardbody pickup. My water pump went out, and I drove to a safe location where I could call a tow-truck.
Here's my question
When a water pump is being replaced, would a blown head gasket be noticeable ?
Thanks
Christie No usually not at the waterpump will you anything weird or unusual. Where you should check is by opening the oil filler cap. If the head gasket was just blown at that very moment you probably can't tell and everything will look normal. If the head gasket has been leaking or blown for some time then you should see foam slimy frothy brown oily liquid when you open your oil filler cap. That is the motor oil mixing with your coolant.
If the car has a head gasket problem (low compression, misfire) but the oil does not show any signs of coolant in the engine, would it be okay to buy the car to drive after repairing the head gasket?
Yeah it is probably ok to drive for a little bit. I wouldn't drive it very hard or far though. Thank you so much for watching!
If I check my oil fill cap and there's a milky color ONLY ON THE CAP and not in the oil pan is that just condensation?
Yes
What would/could be the cause of an LT1 over heating when parking?
The car starts overheating fast when I'm slowly manuvering (Few feet forward, few feet back etc) into a parking space
Car is fine at all other times
Water pump, thermostat, and coolant are all about 1 year old
I bled the system
Fuses and box LOOKED ok
Just put on a new ac delco rad cap
Unplugged the WP to test the fans and the drivers side works but NOT the passenger side
Neither the AC or the heat hasn't worked for over a year btw
TU & subscribed.
Questions: my 98 Sonoma 2.2L with 176k is having the head done (blown gasket....previously paid ($1,350) to a shop mechanic 1 month ago who ripped me off not doing anything to the warped head, amongst other faults.
Now the head is being pressure tested, milled and valve job for $350 by professionals with a guarantee.
I think it now wise to replace the coolant & oil pumps even though no prior indication of faults.
I plan to replace the piston rings from the top. Doable?
Would you suggest the timing chain as well?
I ask about the chain partly because I see some kits that have the two pumps and chain together implying this is normally done together. Is the Cloyes that does away with the tensioners a better choice than OEM?
I am poor and unemployed just trying to be proactive. Am I going too far?
Thanx, Mark
ps...I prefer to keep this truck, other than the current problems it is in perfect condition.
The chain usually doesn’t need to get changed. The belt usually needs to get done and while you’re in there it is an extra 10 minutes to do the pumps. This is probably a leftover from the belt kits, where guys are just trying to sell a bit more and do a kit. Unless there is something wrong with your timing or it is damaged in some way, you likely do jot need to do the chain.
Okay there's no milky residue in oil or on oil cap, there's no bubbles in radiator, but two spark plugs did appear to look like they had rusted a bit. There is so many other things happening with this vehicle and I was hoping that some other problem could possibly make spark plugs look that way. Car runs fine, it randomly runs hot if idling, although it doesn't go any high hot but needs some water every time. Thermostat was put on thinking that would help, I noticed the top hose running from radiator to thermostat was very hard and hot...IDK what to do
fan clutch?
Egg
Prob too late to say this now but change the cap maybe ? 😂 the cap to the radiator and the cooling system
Please help 🙏 My car was sitting for 3-4 months in cold weather with dirty oil. When I checked the oil now, it’s milky. Do I have a blown head gasket?
Sounds like it. I just did a video of Blue Devil head gasket sealer you might be interested. Thanks for watching!
Guys Test Number 3 is Enough for Gasket checking if the bubbles are coming out or blowing.. Your gasket is over.. Replace it as soon as possible.. otherwise.. wait for the engine to get blown!
My car is a 3 cylinder. Has no mayo, some coolant has been used over maybe 2 or 3 months but not huge amounts. Did a compression test and cylinder 1 and 3 were 185 but cylinder 2 was 150.
I can also hear an audible whistle between 3 to 4.5k revs. sounds like a exhaust leak but it is not as I've had a new one fitted and took it to the garage 3 times as I was not sure.
Cylinder 2 also misfires is left at idle for 10 minutes.
I've taken my car to 4 garages and one specialist who couldn't find an issue. What could be wrong?
I know it's a bit late, but out of curiosity, was it a Sandero TCe?
@Dorian no it was a 2006 vw polo 1.2l I have since sold the car and now drive a 2007 mk5 golf gti
Take out the oil and look at it if coolant gets in it will show.
My 07 Versa became overheated... took it to the mech. Pour some liquid.. it was leaking at the bottom. Fix the hose, n now the ignition coil was filled with oil... it struggled a lil bit to start the car. Put a new gasket n I.coils. now it runs fine, but it feels a lil weird when driving it.. like if not fixed all the way. What could be the final verdict? Is the car done?
So is number one always present when the head gaskit is no good?
i changed the spark plugs the spark plug wires the ignition coils the intake manifold and the car is still shaking so i went to a mechanic and he did a leak down test and a compression test. then he said two of the cylinders have low compression and that's what's causing the car to shake, so he said i have to do a head job. i did a head job already on this car back in 2014 and it's 2021 so 7 years and i have to do another one
Luv the Music💕💕💕
the way I found out was loss of power
Mines spit small puddles of coolant out the exhaust.
Mine barreled giant white clouds of smoke
My mate hit debris, rupturing his radiator, overheating the engine which led to the head gasket failing tremendously! All on my 21st birthday 😂
My 2000 Sts blew thick white smoke...lost power....but no milky goo under cap... Someone told me it could be somethin else other than gasket since oil not milky.. Exhaust has sweet smell to it...
@Buick Regal Do you think head gasket repair will help?
Some of these are dependent on the spot where the void is present right? Stupid question but ive had an open space in a gasket before not present with no discolored exhuast, or mixing of fluids. Only accelerating sluggishness and obvious misfires
I have an 06 charger rt, new water pump, new coolant reservoir, new thermostat. No leaks, the fans come on when they're supposed to, yet my coolant still boils over and runs hot?
It sounds too obvious, but did you replace the radiator cap? Fixed my Subaru.
In my car no overheating problem but once in the week when I check the oil dipstick minor milky deposit r found...! What I can do...?
Hi, my Chevrolet Optra 2010 engine overheating. I noticed the coolant level was low and filled it up to MAX and drove around 3 days. Air conditioning was on while I was driving it, suddenly became so hot in the cabin. I stopped the car and the engine went-off on it's own. The engine couldn't be ignited there after. I took to mechanic and he said, the cause was due to engine head-gasket. He changed the head-gasket but the problem still persist, engine still overheats within a 5 minutes and gauge rises from 1/4. Mechanic said, now only engine fully has to be changed. Any suggestion please? I also noticed leakage from the coolant cap, replaced it, then seemed fine. Please share some information. I really appreciate your feedback. Thank you very much.
Change Mechanic!
