My wife's prius had typical engine misfire problem - toyota dealership diagnosed it as dirty egr and cleaned it for $1000. just couple of week after repair prius developed full blown head gasket with plumes of white smoke coming out. Thanks to your head gasket replacment video, I might be able to do it myself and save over $3K in repair cost.
My car was working fine and saw a video talking about how egr cleaning will make the prius smoother and more powerful. I cleaned it, couple of days later, boom - misfire and white smoke from the exhaust 😢

Just had my 2013 done at your shop in Manteca. Very fast and great work ! Dropped it off and picked it up same day… very impressed I saw they even took the time to mark bolts to ensure they didn’t leave anything loose! Great work guys thanks again !
Oh man not sure how I missed your video! U did a fine job explaining the issues with these hybrid engines, you are spot on!! I studied these 1.8 engines both hybrids application and non-hybirds, after reviewing what I learned using scanner software Data I saw that the hybrids have a large widow in temp range anywhere from 165-192 degrees in stop and go traffic, and where the non-hybirds engines are consistent around 196-198 degrees! As u mentioned felpro redesign theirs gasket to help with the fluctuating thermals cycling and improved their head bolts too! So far zeros issues using felpro products in 3th gen prius!
My 2012 Prius V with 140k miles had the exact same symptoms that Walt described in the video. My local mechanic wanted $4K just to diagnose the problem. The Toyota dealer quoted $5-6k but said they couldn’t tell me what it was until they opened it up. Thankfully I stumbled across this video and Walt came out to my house to replace the head gasket at a MUCH more reasonable price point. He showed up on time and finished the job before lunch. I highly recommend these guys. Thank you Walt!
this is a basic job...I have a toyota 2012 prius V and my mechanic changed the head gasket and also the water pump...it cost me 2400 dollars and the car now is 543 000 miles.
Great explanation. I had a cylinder 2 misfire on my 2010 Prius, I knew it was a head gasket, I took it to an independent shop, they wanted to charge me $4k for a new (used) transmission. I’m now in the process of taking off the head at my house.
Nice! Gonna replaced the head gasket in my 2008 Prius this weekend. Toyota needs to improve the design, otherwise, it’s sarcastic that you save $2000 in gas, then spend extra $2000 to replace the gasket
@@merlinarmstrong8346 check the fuel injector too. I replaced the gasket but didn't solve the problem, and it ends up with failed fuel injectors. I replaced them, the baby now drives 49MPG

Man I had my doubts but this dude is legit 👌 Gasket masters set up an appointment with me and came within the 2 days and did work on my Prius! Did exactly what he said and my car is running like new 😌 very professional and clean Job definitely recommend if you having the same issue explained in this video! Thanks man 🙏
I'm thinking of doing the same. How long did the work take? Was it 2 guys that came to do it? Which city? How is it holding up so far? Sorry for all the q's !
Thanks for the explanation. I asked the service advisor at my dealer, and he talked about electrolysis. My mind went blank. You really satisfied my curiosity.
Electrolysis has nothing to do with the head gasket failing or engine overheating. If he meant electrolytes, that’s just referring to the ph balance of the coolant in regards to it’s ability to carry a current, or allow metal to react by oxidizing (rust). He’s either a super genius beyond my level of understanding, or he doesn’t know anything and wanted to sound smart. Thanks for the comment.
how to make electrolysis: 2 fingers in the electric outlet, two fingers on the other hand in a bucket of water. thats how you do electrolysis. seems like this is what this mechanic was doing all night long.
Maybe clogging EGR system is a big factor too? 3rd gens are the first to have this system, and it appears to be woefully under designed. Cross-sectional area insufficient, and the intake UPSTREAM of the Catalytic converter. The EGR cooler slow-but-sure clogs up with carbon, ditto for the valve, the pipe, and the small EGR passageways in the intake manifold. Proper flowing EGR is paramount for keeping engine temperatures in normal range. As it clogs, the temps go up. Which probably accelerates the carbon build-up, and overly stresses the head gaskets.
@@gasketmasters Well, that's debatable. 3rd gen is first to have this "mark I" EGR, and also the gen where the head gasket are failing in such large numbers, and so early. For 4th gen, they've pretty much DOUBLED the cross-sectional area of the EGR, and revised the intake to be downstream of the CAT.
@Gasket Masters The whole purpose of having EGR is to lower combustion chamber temperature. The lower temperature reduces NOx emissions. If the EGR is plugged up, the combustion chamber temperature will shoot up making the engine temperature cycling more extreme. And your explanation of the gasket failure by temperature cycling fits the timing of having the gasket fail after the EGR stops working.
Yeah, I agree. The biggest difference between the two gens (2/3) is the EGR design. I don't buy the explanation in the video as the root cause of all of these failures.
Hi! Can any mechanics here help me out? I just bought a 2010 Prius 135k first 3 weeks are fine this morning I got this hard knocking noise upon a cold start… Now people said you would lose power and also mpg would go down if it’s the head gasket and not the EGR VALVES… I drove it today 200 miles and still getting 45-50mpg. I’m so stressed 😂 not even one month.
Just replaced head gasket on my 2012 Lexus CT200H (same engine as Prius). Tried everything on TH-cam before the head gasket, but in the end the head gasket was the fix. It was not as hard as I had dreaded. Thanks for the video. Like others have said it was very informative.
@@igorb81 I took my time, didn't want to miss anything. Bought a repair manual off of Ebay. Probably an all day job maybe 2. I did a little at a time during holiday so a week for me.
great video! I got a 2013 prius v 3 years ago with 80k miles. I have 190k miles on it now and it is having this same issue. I changed plugs and coils to start but nothing changed. Then I blocked off the egr because I thought that was the issue. No luck. After checking my engine over I can clearly see the head gasket was redone at some point before I got the car. So I'm going to change that next. My car is having all the symptoms you talked about in this video so I hope this is the problem. Thank you for this video!
My Toyota mechanic said it needs a new engine. No explanation how he arrived at that conclusion. I left to go home and a check engine light was on when I left the dealership. I got home and used my Bluetooth scan tool and it said misfire in cylinder 2. Mind you when I took it in had no check engine light on. My car drives smooth just rattles and shakes in the morning.
It is an interesting theory. I wonder why 1st and 2nd generation prius never have head gasket failure. I believe there is a design issue at work here as well.
@@gasketmasters thank for your reply, I’m considering a Honda Accord hybrid, are there any modifications that I can do to eliminate this issue potentially grounding me or should I just avoid the hybrid all together as I may need it for work requirements. Apologies for the thread hijack 👽
Why are you not mentioning the NEED to check for a bent rod? This is a 13 to 1 compression engine. Doesn't take much coolant to lock it up. Mine had a #1 bent rod, luckily I CHECKED. I replaced with a Gen 4 eng. Much better Piston and ring design with minimal conversion
On my 2011 I did it all. Head gasket, EGR valve, and EGR cooler. On cold mornings, I'm still getting a small amount of rattle about 1 minute after start up. it has P0302 P0300 P0304 I've exchanged the #2 & #4 coils with #1 & #3 coils to see if the misfireings are going to migrate.
Awesome explanation. My 2010 prius has about 350K miles on it. I got the cylinder 1 and 2 misfire. I did the chemical test and it confirmed that I do have a blown head gasket. A part of me wants to replace the head gasket myself, but there is also another side of me that just wants to put one of those sealant and hope it last another year. Still debating on if I should just do the replacement myself.
I'd just get the head gasket done if you plan on keeping it. I used the thick silver Barr's Leaks and it lasted 10k before needing more. Lost a water pump not too long after the 2nd use but the car had like 220 thousand miles so it may have been going anyway, that's normal time for that type of part. Though after my 3rd sealant use the heater core clogged. Now it sits in the garage needing 4k in work, though still runs fine for short trips, just no heat.
I used the Moroso ceramic block sealer, I’ve put about 40k miles on it so far & it’s holding no problem, If it fails I’d just do the Moroso treatment again since it only cost me about $40 total.
I always wondered why block and head can’t be a single piece. The pressure, heat and gas plus the stress on bolts are all because of the two pieces bolted together.
Real....🔥🔥🔥🔥 Big ups for the Prius Head Gasket information....I've been doing my research and your video has helped me narrow it down to the solution for my 2012 Toyata Prius , Respect..!! ✨🔥🤙🏽
God bless you got the same problem as you described and I didn’t know what was wrong my mechanic said it might be the gearbox you save me a lot of money and headache God bless you again and thank you.
Gasket Masters, It is a really good explanation and agrees with metallurgy. Toyota should put more money in research and development of head gasket for their Hybrids. Through alloy formulation, layers optimization, and annealing process, optimum gasket properties could be achieved. In Europe 70% Toyota sold as hybrid in all cars (Prius, Corolla, RAV4, Yaris, Camry, Highlander, ES,GS,LS,RX). Do you have enough statistics for reliability on 1.5 L (Prius C), 2.5 L and 3.5 L V6 Hybrids in Toyota?
Fel-Pro, a gasket company, used to make a Teflon-coated head gasket that allowed the cylinder head to slide on as the cylinder head expands and contracts.
I have 04 Prius with over 300,000, never had to do a head gasket, also a 2010 with over 200,000. Also no head gasket problems. Biggest problem for 3rd gen is the EGR system. I just cut a piece of metal and blocked it off
Yep. Replace it and coolant every 100k miles with a new OEM unit and this shouldn’t be an issue. I did mine at 125k. They seem to fail between 100 and 175k apparently.
@Gasket Masters 2012 prius with 180k miles. Started having the head gasket issue. I have a lead on a 2015 prius motor with 50k miles. Are the 2015 models any better about this issue or would the gasket fail similarly on these models as well? Trying to decide between motor swap or head gasket replacement.
Tradu text folosind camera foto I understand that on the 2014 and 2015 models of the Toyota Prius, they changed the cylinder head gasket to a better one. This is true ? Plus, Toyota recommends changing the water pump after 200 miles, which is the main reason the head gasket fails. Thanks!
If the coolant is keeping the head at a constant temperature, surely there is no constant expansion and contraction ? I was always under the impression it was water pump failure that caused it.
Here in the Netherlands the 3rd gen prius and ct200h are not known for blowing headgaskets. Never heard or seen one which has had regular maintenance. Maybe we have better fuel?
Great explanation, though is there a difference between the in head gaskets in Gen2 (no head gasket problem) and Gen3 Prii???? Why is it specific to the 2010 + ?
I know that the whole EGR system gets really clogged up on the Gen3 and not so much with the Gen2. The clogged EGR perhaps causes the engine to cycle on and off more often?
If this were 100% true wouldn't second generation Priuses also be prone to headgasket failure? The consensus in the Prius community has shown that head gasket failure is almost endemic to the third generation 2010-2015, but even less so for years 2013-2015 due to numerous revisions in 2013 including EGR/Intake Manifold design changes. What are some of the differences between second generation (2004-2009) and third generation Priuses you ask, well most importantly the second generation has no EGR system that is prone to clogging or failure which has been witnessed very commonly in the third generation leading to changes in internal temperatures.
The 1st and 2nd generation have a different engine which seems to be less sensitive to the leaking of coolant into the cylinders when the head gasket starts wearing
@@selvaspk2324 Replace/clean egr frequently(every year). You could try to let the engine warm up, tho not sure how much can you do in city traffic to force it to run, since its where its meant to run the petrol engine the least.
My 2013 Prius started doing this in June. Dealership diagnosed EGR, charged me $2100, even though I told them it sounded like a head gasket. But it didn't fix it. Took it back and the said they ran leak checks, and blamed the carbon buildup on loose piston rings. I told them that the problem went away if I took the cap off the coolant reservoir, and couldn't afford an overhaul. Left bad reviews online that got a mgr's attention and a refund of the $2100. Now, the symptoms have returned, even with the cap off. Hope your replacement tutorial gives me hope....
The head gasket job is not hard as long as you have time, common sense, and patience. I just finished mine and the car runs better than the day I bought it. Just remember to clean everything thoroughly, replace the PVC, and plugs... you will have yourself a renewed Prius. Save money where you can and the advice given in this video is great.
Great explanation… Thank you. I have noticed from some of your other videos that you can do a head gasket in a day. That obviously means that you do not take it to a machine shop and have the head ground flat. Do you find that in the case where it just starts using Excess coolant that the head does not need to be machined?
awesome work guys! so... a 2014 prius handled 5,000 miles per year driving in a city with constant and moderate climate would be less likely to develop a head gasket problem? thanks!
The thing is, though, Gen 2 (2004--2009) Prius doesn't have this problem. It's Gen 3, so they changed something or it's the EGR clogging problem. My Gen 2 has 350k miles, no engine problems, no coolant loss, ever.
[1:35] You know these guys are about their business the way he took that gasket out 👏 With all you just said, because this wasn’t an overheating issue due to auxiliary parts (water pump, thermostat, etc.), would you still recommend putting all these components in new?? Getting ready to do this for my friend but trying to save them money and just do the essentials (all new gaskets, head bolts, coolant etc.)
Is there a way to test when the head gasket is going to go bad? I'm trying to decide if I need to sell the car before the head gasket blows. I just spent $3300 replacing the brake actuator and I can't afford another expensive repair, and I'd rather sell while I can still get something for it.
Great explanation, but the defective ring and piston design in the Gen 3 engine often leads to extreme oil burning and EGR cooler clogging. So fixing the head gaskets is not a guarantee of a trouble free future - especially if your Prius is already an oil burner. For this reason I just put in a rebuilt engine with Gen 4 pistons & rings and hope to get another 100K miles - it cost $4,600 installed at Hybrid Pit Stop in LA - they sell these rebuilt engines on eBay.
This was so GREAT!!!!!!! I just had my Prius now need a new engine for it crack because #2 cylinder I can understand now why my mechanic is not good He did not check the engine when the check engine came on. Failed #2 replaced drove for a week and check engine light came on again....We he told me I needed a new engine. I only had 175,000 mileage... I drive 500 miles a week to work mainly freeway driving
The check engine light gave me those codes seen in the description. Those codes don't really point to bad head gasket so you start replacing plugs/coils etc. But Gasket Masters has given us the REAL reason for the check engine light.
It all depends on the type of driving. There is a current 2019 Prius prime owner that uses his vehicle for medical deliveries. He has just over 500,000 miles on the car and hasn't had any issues. The reason? 90% of his driving is in the highway where the engine stays running the majority of the time So there are less heat cycles.
Thanks for the info man you rock 👊. I've been having issues with cold start rattle when the car sits for a few days, despite changing the hg 40k miles ago.
You might be referring to the brief rattle on a cold engine that's present in many Toyotas caused by the intake camshaft timing gear assembly. I'm aware they've issued TSBs for this issue, specifically T-SB-0087-09 for the 2ZR engines for 2009-2010.
Also check to see if your spark plugs or coils are bad. I know my Prius definitely vibrates a bit more at cold start after sitting overnight. Relatively easy thing to swap and see if it fixes it
@@sueellenmcgoey8708, do you mean twice failed head gaskets or twice you heard the cold start rattle? If it's the latter it means it isn't a serious issue (unless it embarrasses you). If indeed you refer to cold start rattle then try this: start up the car when it's cold and listen for the rattle - if you hear it, good. Shut down the engine then start up again immediately. If it's because of the camshaft timing gear issue you won't hear any rattle the second time. And if you've confirmed the above test to be the case, I'll tell you something: many people are driving their cars with it because it's not affecting performance and isn't an urgent problem. I've driven mine like that for about 23,000 km (~14,300 mi). It is not an extremely complicated fix but the OEM part isn't going to be cheapest ( toyotaparts.mcgeorgetoyota.com/oem-parts/toyota-engine-timing-camshaft-sprocket-130500t050?c=cT0xMzA1MC0zNzA2MA%3D%3D) I presume you refer to the 1.8L engine
Hi, amazing explanation, could you share your opinion - in case of Hybrid(Prius Alpha 2018) 2ZR FXE engine on board, when it's time to chenge this gasket?
My 300,000 mile 2013 started to misfire with and I changed the spark plugs and such. It continued and I took it to the Toyota dealership repair center. He told me about dropping the gasket rings or something weird. He never mentioned a head gasket. Maybe that was in the process. He has had my car for 2 days. Quoted me around $400 repair.
@@gasketmasters it's riding better with a few misfires so far after a 20 minute drive in stop and go traffic. They did a gasket drain and cleaned the cylinder. Cylinder 2 was burning out the spark plug. I had an oil leak also. They ran it for a few days. They charged $120 for the diagnosis if I did no work with them.
@@napynap How much of a coolant drop? It's hot here in Atlanta. I noticed my coolant level dropped by about 1/8 to 1/4 inch and so I topped it off. Three days later I'm getting P0300, P0301 & P0302 codes with MAJOR start-up rattling.
Thanks for the great explanation! What would be the life expectancy for the water pump and inverter water pump? And where is the common oil leak on this engine?
replace the water pump BEFORE it goes bad. TRUST ME. 120k tops. mine went out at 140 but definitely replace it before it goes bad. this is soooo important
I took my 2010 Prius to a Toyota dealership ( stone mountain Toyota in Georgia ) they said it was my intake manifold, then my coils, so 2 grand later they still didn't know what was wrong with it. They then have to run diagnostics twice for 4 days. which they provided a rental for those days as if that really helped. But then come back and tell me I need a new head gasket (3.5k after taking 2k off for the stuff I already had done) after I spent 2 grand and have no more money they tell me this. So now I think I'm going to get a loan, call gasket masters, and drive 9 hours to Florida. =)
2 reasons off the top, 3rd gen has an electric water pump and when it suddenly dies, so does your head gasket due to overheating. 2nd, the 3rd gen has an elaborate EGR system prone to clogging leading to excessive cylinder temperature. Both of these are serviceable items. I addressed both on my car as preventative measures at 125k.
@@repairvehicle This is the theory on PriusChat. Nobody has proven it definitively it, however a clogged EGR system has strong correlation with head gasket failure including manny repeat failures when the EGR system was not cleaned when the head gasket was replaced. Could be from temperature, pressure, or both, that’s an ongoing debate but the relationship to head gasket failure is quite certain.
@@mylesgray3470 , what I have found. Head gasket fails from to many cycles heat no heat. Metal can take so many cycles before it fails. Head gasket is made from Metal. Egr cooler designed to cool off exhaust gasses before they are routed back for burning inside cylinder. Only partial gasses enter combustion chamber at given times.
how often is this happening. Im looking at a ct200h tomorrow for around 5k The guy says it has a blown gasket. Its way over priced if so. Even with a blown gasket i can find prius for 1500 around here.
I have same problem on my 2013 Toyota Corolla LE 1.8L 2ZR-FE engine and like to know if new improved head gasket (shown on video as blue) has OEM p/n or it is aftermarket? Thanks.
This issue seems to be prevalent in the 2AR-FE as well. My mother's 2015 Camry (Very well maintained & not beat on) without warning, it blew the head gasket at 38k mi. The only DTC's were P0302 & 303. (Important for her case study). The Local Toyota dealership ran their diagnostics and maintenance history, and pushed back trying to deny the manufacturer warranty claim for the "H.G" due to in her maint. history, she had got her oil changed a few weeks before (Late June) by an "express" style oil change franchise, and they used 5w-20syn. Toyota tried to deny the claim because on the oil fill cap it says 0w-20syn. 😂 Too bad it states in her camrys owners manual, that during spring/summer months, it's 100% safe and suitable for the 2AR-Fe. I stepped in on her behalf, as a certified Auto mechanic, my first question for the head tech of the warranty & service department was, "were there any VVT, cam/crank correlation, EOP DTC's current or stored?" - No. "Was there any coolant temp. related DTC's?" - No.........😬 "So just the 302 - 303 misfire's?" - Yes.......😳 Umm you might want to contact your superiors at Toyota global warranty center. 🤔 - 20mins later he came back saying, "Her claim was approved finding her clear of any cause of failure & set her up with a free loaner car until her Camry was repaired. Nobody is going to rip my mom off on vehicle repairs, damn sure not the dealership! 80k since the repair and it's been ok. Now just yesterday it set a P0420 🥴 fml😅
It shouldnt be a frequent occurence if it is then there is something wrong or gaskets installed are very bad. If its designed well it should last for at least 300-350k miles. In Prius main problems are both design (too narrow gaos between cylinders and open deck design) and hybrid system which doesnt let the engine fully heat up and keep the temperature.
Some people blame the electric water pump or a clog egr cooler and intake manifold. I'm having my 14' 180k miles leaking from cylinder 2 I'm going to replace gasket and head if need be an see what happens. I'm also going to replace water pump and clean egr or intake. My 2005 has 290k and no issues like this. Maybe bad quality head gaskets where installed from manufacturer or thinner walls where cylinder and coolant passage divide vs as compared to generation 2
@@lobogris4806 yes the official reason is from EGR even normal function causing carbon buildup on the piston ,this start touching the head and the slight deformation in the aluminium causing the leak. best to do is to check pistons with camera. gen 2 has no EGR but waterpump often leak a bit

This explanation seems to apply to all hybrids in which temperatures fluctuate due to the engine frequently turning off. Should all hybrids suffer earlier gasket failures then? Or could it be just a poor gasket design for the Prius only?
@@hedgehogthesonic3181 ok - that’s too early for this issue to show up anyway. It typically shows up at 150,000 to 180,000 miles. But I have indeed heard that the 1.5 l engine in the Prius C is less susceptible to this problem than the 1.8 l in the regular Prius.
Makes sense. I'm an uber driver and have the car running 24/7. Don't shut it off when going into stores, end up sleeping in my car 50% of the time. (Because too tired to get home). I drive about 15 hours a day. Got 300k out of my prius on original gasket which is impressive. Probably going to use a sealer. Idk maybe I'll change the gasket. It's got 300k miles on it, might as well try the sealer, and if it don't work, get a new engine.
Thanks so much for the great videos! I have a blown head gasket on my 2010 Toyota prius (milk in the oil) and you videos have given me the knowledge to talk intelligently interview mechanics for a replacement gasket. I wish I lived near your service areas.
Don’t replace it unless you have misfire symptoms, my 2012 Prius just went over 200k without any HG symptoms. Dealer replaced the EGR @ 146k miles because it was a recalled, I did replaced the water pump and PVC valve @185k miles just for preventative maintenance.
So I'm getting all this symptoms, but no coolant loss, and compression is even across the cylinders. 150/155/160. Started with P0300, P0301 P0303. New egr valve, recent PCV valve change. Now intermittent rattling at lower rpms. Cylinder 2 misfire but not enough to throw CEL. 2013 prius 274k miles How do I make sure it's a Headgasket failure without going to the shop???
Go to your nearest auto parts store. Rent a “combustion leak tester”. It’s a plastic tube that has a cap with a hole on top to fit a suction cup or rubber hose, and a cone with a small hole in it on the other. Pour a small amount of the included fluid in the tube and cap it off. Remove the reservoir cap and put the cone on it. Have an assistant start the car. (If the car is in ready mode, have the assistant give it just enough gas pedal to kick the car on, or turn the heater on high temp, high fan). Draw a vacuum on the tube and watch the fluid color. If it changes, the head gasket is blown.
Helped my son replace his Prius head gasket a few weeks ago, it is running fine now. However, we had called a few shops to get a quote, but none of them wanted to do it on a 2012 Prius, the one shop that gave an initial quote of around $3500, then asked how many miles, when we said 175k, they then said, no they wouldn't do it, too high of mileage. Something about liability. What is up with that?
thanks for the vid. my car is a 2013 hybrid toyota 3rd gen i noticed a high coolant consumption on engine with poor engine power. but no oil consumption . is this could be a sign of a failure head gasket ?
Hi! Im having issues with my 2011 prius I just bought it recently it has only 134k miles and I just got back from a vacations trip it was like 3 thousands miles round trip and I put like 4 quarts of oil total and I noticed the car has like black stains I. The rear bumper and rear door like if the car was smoking or something. Pls help any idea what it can be? I just replace the PVC valve and still burning oil like crazy . pls help! Do I need to replace head gasket? That's what I'm thinking but I'm not sure help!!!!!!!!
I wish I would have seen this video 2 years ago. My 2010 Prius died after 196k miles. It would do the rattle a lot at startup. At the time, nobody really knew what it was. It steadily lost power, clicking in the engine, and noticed coolant getting low all the time. When I took it to the dealer, they took the info, and wouldn't actually do a pressure test without a big fee and NEVER mentioned head gasket. I ended up buying another car now, but still have the Prius. I may try to have another engine put into it, but then again, the Hybrid battery and Catalytic converter probably will only have 100k left anyway, so might not be worth it.
My wife's prius had typical engine misfire problem - toyota dealership diagnosed it as dirty egr and cleaned it for $1000. just couple of week after repair prius developed full blown head gasket with plumes of white smoke coming out. Thanks to your head gasket replacment video, I might be able to do it myself and save over $3K in repair cost.
I would see if they wont give you a refund on the EGR cleaning, it was misdiagnosed.
My car was working fine and saw a video talking about how egr cleaning will make the prius smoother and more powerful. I cleaned it, couple of days later, boom - misfire and white smoke from the exhaust 😢
1000 for egr cleanup? it only takes a couple of hours.

I studied these 1.8 engines both hybrids application and non-hybirds, after reviewing what I learned using scanner software Data I saw that the hybrids have a large widow in temp range anywhere from 165-192 degrees in stop and go traffic, and where the non-hybirds engines are consistent around 196-198 degrees! As u mentioned felpro redesign theirs gasket to help with the fluctuating thermals cycling and improved their head bolts too! So far zeros issues using felpro products in 3th gen prius!
I love your videos. This is best explanation of blown head gasket I've seen. Your video about the repair was gold. Used it to do mine.
My 2012 Prius V with 140k miles had the exact same symptoms that Walt described in the video. My local mechanic wanted $4K just to diagnose the problem. The Toyota dealer quoted $5-6k but said they couldn’t tell me what it was until they opened it up. Thankfully I stumbled across this video and Walt came out to my house to replace the head gasket at a MUCH more reasonable price point. He showed up on time and finished the job before lunch. I highly recommend these guys. Thank you Walt!

Great explanation. I had a cylinder 2 misfire on my 2010 Prius, I knew it was a head gasket, I took it to an independent shop, they wanted to charge me $4k for a new (used) transmission. I’m now in the process of taking off the head at my house.

Hi how much they charge and how car still
Thanks for the explanation. I asked the service advisor at my dealer, and he talked about electrolysis. My mind went blank. You really satisfied my curiosity.
Electrolysis has nothing to do with the head gasket failing or engine overheating. If he meant electrolytes, that’s just referring to the ph balance of the coolant in regards to it’s ability to carry a current, or allow metal to react by oxidizing (rust). He’s either a super genius beyond my level of understanding, or he doesn’t know anything and wanted to sound smart. Thanks for the comment.
👍😂🤣
A master of a skill knows how to explain it in the simplest of terms anyone can understand to some degree.
how to make electrolysis: 2 fingers in the electric outlet, two fingers on the other hand in a bucket of water. thats how you do electrolysis. seems like this is what this mechanic was doing all night long.
Glad I came across this. I'm doing the same job and after pulling the gasket couldn't really see where the failure point is. This explains it. Thanks!
Very informative video, thank you. I don't even own a Prius, just curious as to why head gaskets on these fail often compared to traditional ice cars.
best explanation ive ever heard in my life rhis is a master mechanic
Maybe clogging EGR system is a big factor too? 3rd gens are the first to have this system, and it appears to be woefully under designed. Cross-sectional area insufficient, and the intake UPSTREAM of the Catalytic converter. The EGR cooler slow-but-sure clogs up with carbon, ditto for the valve, the pipe, and the small EGR passageways in the intake manifold.
Proper flowing EGR is paramount for keeping engine temperatures in normal range. As it clogs, the temps go up. Which probably accelerates the carbon build-up, and overly stresses the head gaskets.
The clogged EGR is a result of temp fluctuations.
@@gasketmasters Well, that's debatable. 3rd gen is first to have this "mark I" EGR, and also the gen where the head gasket are failing in such large numbers, and so early. For 4th gen, they've pretty much DOUBLED the cross-sectional area of the EGR, and revised the intake to be downstream of the CAT.
@Gasket Masters The whole purpose of having EGR is to lower combustion chamber temperature. The lower temperature reduces NOx emissions. If the EGR is plugged up, the combustion chamber temperature will shoot up making the engine temperature cycling more extreme. And your explanation of the gasket failure by temperature cycling fits the timing of having the gasket fail after the EGR stops working.
Yeah, I agree. The biggest difference between the two gens (2/3) is the EGR design. I don't buy the explanation in the video as the root cause of all of these failures.
Hi!
Can any mechanics here help me out?
I just bought a 2010 Prius 135k first 3 weeks are fine this morning I got this hard knocking noise upon a cold start…
Now people said you would lose power and also mpg would go down if it’s the head gasket and not the EGR VALVES…
I drove it today 200 miles and still getting 45-50mpg.
I’m so stressed 😂 not even one month.
Just replaced head gasket on my 2012 Lexus CT200H (same engine as Prius). Tried everything on TH-cam before the head gasket, but in the end the head gasket was the fix. It was not as hard as I had dreaded. Thanks for the video. Like others have said it was very informative.
That’s great to hear. Thank you
you did it yourself? how long did it take you?
@@igorb81 I took my time, didn't want to miss anything. Bought a repair manual off of Ebay. Probably an all day job maybe 2. I did a little at a time during holiday so a week for me.
great video! I got a 2013 prius v 3 years ago with 80k miles. I have 190k miles on it now and it is having this same issue. I changed plugs and coils to start but nothing changed. Then I blocked off the egr because I thought that was the issue. No luck. After checking my engine over I can clearly see the head gasket was redone at some point before I got the car. So I'm going to change that next. My car is having all the symptoms you talked about in this video so I hope this is the problem. Thank you for this video!
My Toyota mechanic said it needs a new engine. No explanation how he arrived at that conclusion. I left to go home and a check engine light was on when I left the dealership. I got home and used my Bluetooth scan tool and it said misfire in cylinder 2. Mind you when I took it in had no check engine light on. My car drives smooth just rattles and shakes in the morning.
Thank you very much for this video!! Supper informational for young mechanics, who haven’t gone to school yet
It is an interesting theory. I wonder why 1st and 2nd generation prius never have head gasket failure. I believe there is a design issue at work here as well.
The cylinder walls on the 1.5 are slightly wider in ratio, therefore less likelihood of leak
@@gasketmasters thank for your reply, I’m considering a Honda Accord hybrid, are there any modifications that I can do to eliminate this issue potentially grounding me or should I just avoid the hybrid all together as I may need it for work requirements. Apologies for the thread hijack 👽
Why are you not mentioning the NEED to check for a bent rod? This is a 13 to 1 compression engine. Doesn't take much coolant to lock it up. Mine had a #1 bent rod, luckily I CHECKED. I replaced with a Gen 4 eng. Much better Piston and ring design with minimal conversion
How do you feel upgrading to 2016 motor? I was told they blow less head gaskets?
On my 2011 I did it all. Head gasket, EGR valve, and EGR cooler. On cold mornings, I'm still getting a small amount of rattle about 1 minute after start up.
it has P0302 P0300 P0304
I've exchanged the #2 & #4 coils with #1 & #3 coils to see if the misfireings are going to migrate.
what did you figure out? sounds like clogged EGR valve, cooler and intake perhaps. this appears to be major issue on 3rd gen
Awesome explanation. My 2010 prius has about 350K miles on it. I got the cylinder 1 and 2 misfire. I did the chemical test and it confirmed that I do have a blown head gasket. A part of me wants to replace the head gasket myself, but there is also another side of me that just wants to put one of those sealant and hope it last another year. Still debating on if I should just do the replacement myself.
On their Gasket Master video removing the head, it shows what the sealant does, not good.
350K on one engine, that is awesome!
I'd just get the head gasket done if you plan on keeping it. I used the thick silver Barr's Leaks and it lasted 10k before needing more. Lost a water pump not too long after the 2nd use but the car had like 220 thousand miles so it may have been going anyway, that's normal time for that type of part. Though after my 3rd sealant use the heater core clogged. Now it sits in the garage needing 4k in work, though still runs fine for short trips, just no heat.
I used the Moroso ceramic block sealer, I’ve put about 40k miles on it so far & it’s holding no problem, If it fails I’d just do the Moroso treatment again since it only cost me about $40 total.
@@Rambleon444 350k on a Prius engine is standard they all go up to that much without any major problems
I always wondered why block and head can’t be a single piece. The pressure, heat and gas plus the stress on bolts are all because of the two pieces bolted together.
Real....🔥🔥🔥🔥 Big ups for the Prius Head Gasket information....I've been doing my research and your video has helped me narrow it down to the solution for my 2012 Toyata Prius , Respect..!! ✨🔥🤙🏽
God bless you got the same problem as you described and I didn’t know what was wrong my mechanic said it might be the gearbox you save me a lot of money and headache God bless you again and thank you.
Gasket Masters, It is a really good explanation and agrees with metallurgy. Toyota should put more money in research and development of head gasket for their Hybrids. Through alloy formulation, layers optimization, and annealing process, optimum gasket properties could be achieved. In Europe 70% Toyota sold as hybrid in all cars (Prius, Corolla, RAV4, Yaris, Camry, Highlander, ES,GS,LS,RX). Do you have enough statistics for reliability on 1.5 L (Prius C), 2.5 L and 3.5 L V6 Hybrids in Toyota?
Fel-Pro, a gasket company, used to make a Teflon-coated head gasket that allowed the cylinder head to slide on as the cylinder head expands and contracts.
I have 04 Prius with over 300,000, never had to do a head gasket, also a 2010 with over 200,000. Also no head gasket problems. Biggest problem for 3rd gen is the EGR system. I just cut a piece of metal and blocked it off
Where did you add the piece? I recently gave my whole EGR system a good cleanout.
@@Ass_Burgers_Syndrome it didn't work long term for me, and then the engine ended up throwing a rod at 220k!
The high temp is the engine killer, hybrids have a most problems with a bad head gasket is due to poor/ faulty electric coolant pump...
Yep. Replace it and coolant every 100k miles with a new OEM unit and this shouldn’t be an issue. I did mine at 125k. They seem to fail between 100 and 175k apparently.
@Gasket Masters 2012 prius with 180k miles. Started having the head gasket issue. I have a lead on a 2015 prius motor with 50k miles. Are the 2015 models any better about this issue or would the gasket fail similarly on these models as well? Trying to decide between motor swap or head gasket replacement.

I understand that on the 2014 and 2015 models of the Toyota Prius, they changed the cylinder head gasket to a better one. This is true ? Plus, Toyota recommends changing the water pump after 200 miles, which is the main reason the head gasket fails.
Thanks!
Great job answering all the comments😊👍👏
If the coolant is keeping the head at a constant temperature, surely there is no constant expansion and contraction ? I was always under the impression it was water pump failure that caused it.
Here in the Netherlands the 3rd gen prius and ct200h are not known for blowing headgaskets. Never heard or seen one which has had regular maintenance. Maybe we have better fuel?
Great explanation, though is there a difference between the in head gaskets in Gen2 (no head gasket problem) and Gen3 Prii????
Why is it specific to the 2010 + ?
I know that the whole EGR system gets really clogged up on the Gen3 and not so much with the Gen2. The clogged EGR perhaps causes the engine to cycle on and off more often?
If this were 100% true wouldn't second generation Priuses also be prone to headgasket failure? The consensus in the Prius community has shown that head gasket failure is almost endemic to the third generation 2010-2015, but even less so for years 2013-2015 due to numerous revisions in 2013 including EGR/Intake Manifold design changes. What are some of the differences between second generation (2004-2009) and third generation Priuses you ask, well most importantly the second generation has no EGR system that is prone to clogging or failure which has been witnessed very commonly in the third generation leading to changes in internal temperatures.
The 1st and 2nd generation have a different engine which seems to be less sensitive to the leaking of coolant into the cylinders when the head gasket starts wearing
How do I prevent Failure? Replace it before it fails?
@@selvaspk2324 Replace/clean egr frequently(every year). You could try to let the engine warm up, tho not sure how much can you do in city traffic to force it to run, since its where its meant to run the petrol engine the least.
My 2013 Prius started doing this in June. Dealership diagnosed EGR, charged me $2100, even though I told them it sounded like a head gasket. But it didn't fix it. Took it back and the said they ran leak checks, and blamed the carbon buildup on loose piston rings. I told them that the problem went away if I took the cap off the coolant reservoir, and couldn't afford an overhaul. Left bad reviews online that got a mgr's attention and a refund of the $2100. Now, the symptoms have returned, even with the cap off. Hope your replacement tutorial gives me hope....
amazing... because you make me understand it what is wrong with my Prius v thanks brother
The head gasket job is not hard as long as you have time, common sense, and patience. I just finished mine and the car runs better than the day I bought it. Just remember to clean everything thoroughly, replace the PVC, and plugs... you will have yourself a renewed Prius. Save money where you can and the advice given in this video is great.
Lol bullshit. Easily 40-60 hours of work of tracking down parts and tools to get it done. For a first timer it's about as laborious as it gets.
Great explanation… Thank you. I have noticed from some of your other videos that you can do a head gasket in a day. That obviously means that you do not take it to a machine shop and have the head ground flat. Do you find that in the case where it just starts using Excess coolant that the head does not need to be machined?
awesome work guys! so... a 2014 prius handled 5,000 miles per year driving in a city with constant and moderate climate would be less likely to develop a head gasket problem? thanks!
How to prevent or prolong this head gasket leak?
The thing is, though, Gen 2 (2004--2009) Prius doesn't have this problem. It's Gen 3, so they changed something or it's the EGR clogging problem. My Gen 2 has 350k miles, no engine problems, no coolant loss, ever.
i always heard it was caused by the egr system don’t these have some kind of coolant thermos to keep the coolant hot when it’s not running the engine
Is water sloshing around in the engine a symptom of this ?
What's the solution to this? How long will a Fel Pro gasket last vs genuine?
I read the piston rings have issues also? Should i do them also? Have 200,000 miles and a miss fire
[1:35] You know these guys are about their business the way he took that gasket out 👏
With all you just said, because this wasn’t an overheating issue due to auxiliary parts (water pump, thermostat, etc.), would you still recommend putting all these components in new?? Getting ready to do this for my friend but trying to save them money and just do the essentials (all new gaskets, head bolts, coolant etc.)
you absolutely rock great video great explanation fixed our Prius!
2020 toyota corolla 2.0 head gasket is damage and I have to buy the engine used $2k 6k miles not bad.
Great explanation!!! Everything is clear and make sense!
What’s the best head gasket brand and where can I buy it?
Thank you so much!
Best explanation on TH-cam
Thank you for this video
Doing the head gasket myself. To shops said the engine has to be pulled can it be done without pulling engine?
Is there a way to test when the head gasket is going to go bad? I'm trying to decide if I need to sell the car before the head gasket blows. I just spent $3300 replacing the brake actuator and I can't afford another expensive repair, and I'd rather sell while I can still get something for it.
Great explanation, but the defective ring and piston design in the Gen 3 engine often leads to extreme oil burning and EGR cooler clogging. So fixing the head gaskets is not a guarantee of a trouble free future - especially if your Prius is already an oil burner. For this reason I just put in a rebuilt engine with Gen 4 pistons & rings and hope to get another 100K miles - it cost $4,600 installed at Hybrid Pit Stop in LA - they sell these rebuilt engines on eBay.
This was so GREAT!!!!!!! I just had my Prius now need a new engine for it crack because #2 cylinder I can understand now why my mechanic is not good He did not check the engine when the check engine came on. Failed #2 replaced drove for a week and check engine light came on again....We he told me I needed a new engine. I only had 175,000 mileage... I drive 500 miles a week to work mainly freeway driving
The check engine light gave me those codes seen in the description. Those codes don't really point to bad head gasket so you start replacing plugs/coils etc. But Gasket Masters has given us the REAL reason for the check engine light.
MY GASKET FAILED AT 213K MILES
It all depends on the type of driving. There is a current 2019 Prius prime owner that uses his vehicle for medical deliveries. He has just over 500,000 miles on the car and hasn't had any issues. The reason? 90% of his driving is in the highway where the engine stays running the majority of the time So there are less heat cycles.
Thanks for the info man you rock 👊. I've been having issues with cold start rattle when the car sits for a few days, despite changing the hg 40k miles ago.
You might be referring to the brief rattle on a cold engine that's present in many Toyotas caused by the intake camshaft timing gear assembly. I'm aware they've issued TSBs for this issue, specifically T-SB-0087-09 for the 2ZR engines for 2009-2010.
Also check to see if your spark plugs or coils are bad. I know my Prius definitely vibrates a bit more at cold start after sitting overnight.
Relatively easy thing to swap and see if it fixes it
@@ucakpan that's happened twice to me.
Should I be concerned?

@@sueellenmcgoey8708, do you mean twice failed head gaskets or twice you heard the cold start rattle? If it's the latter it means it isn't a serious issue (unless it embarrasses you). If indeed you refer to cold start rattle then try this: start up the car when it's cold and listen for the rattle - if you hear it, good. Shut down the engine then start up again immediately. If it's because of the camshaft timing gear issue you won't hear any rattle the second time. And if you've confirmed the above test to be the case, I'll tell you something: many people are driving their cars with it because it's not affecting performance and isn't an urgent problem. I've driven mine like that for about 23,000 km (~14,300 mi).

Do the camry 2.4 engines have these problems?
My 300,000 mile 2013 started to misfire with and I changed the spark plugs and such. It continued and I took it to the Toyota dealership repair center. He told me about dropping the gasket rings or something weird. He never mentioned a head gasket. Maybe that was in the process. He has had my car for 2 days. Quoted me around $400 repair.
Most likely it wasn’t the HG then. Was it repaired or was that the price for them to diagnose?
@@gasketmasters it's riding better with a few misfires so far after a 20 minute drive in stop and go traffic. They did a gasket drain and cleaned the cylinder. Cylinder 2 was burning out the spark plug. I had an oil leak also. They ran it for a few days. They charged $120 for the diagnosis if I did no work with them.
@@mostmost1 If you start noticing a drop in coolant level, get the HG replaced immediately, because next will be piston knocking.

Mine is leaking coolant. Any specific coolant needed for a Prius? And do you add this coolant to both reservoirs?
So has Toyota figured out a fix on this? We have a 2018, so will it happen to us?
Thanks for the great explanation! What would be the life expectancy for the water pump and inverter water pump? And where is the common oil leak on this engine?
replace the water pump BEFORE it goes bad. TRUST ME. 120k tops. mine went out at 140 but definitely replace it before it goes bad. this is soooo important
I took my 2010 Prius to a Toyota dealership ( stone mountain Toyota in Georgia ) they said it was my intake manifold, then my coils, so 2 grand later they still didn't know what was wrong with it. They then have to run diagnostics twice for 4 days. which they provided a rental for those days as if that really helped. But then come back and tell me I need a new head gasket (3.5k after taking 2k off for the stuff I already had done) after I spent 2 grand and have no more money they tell me this. So now I think I'm going to get a loan, call gasket masters, and drive 9 hours to Florida. =)
That why I always pay with a credit card you can dispute that and get your money back but it's probably to late.

I'm just starting with the 20 second rattle on start up😢
I am not a uber or taxi driver but our 2013 prius have 206.000 kilometer on the clock. With how much will this happens?
Very interesting. Why second gen prius don't have this issue?
2 reasons off the top, 3rd gen has an electric water pump and when it suddenly dies, so does your head gasket due to overheating. 2nd, the 3rd gen has an elaborate EGR system prone to clogging leading to excessive cylinder temperature. Both of these are serviceable items. I addressed both on my car as preventative measures at 125k.
@@mylesgray3470 clogged up egr system has nothing to do with excessive cylinder temperature.
@@repairvehicle This is the theory on PriusChat. Nobody has proven it definitively it, however a clogged EGR system has strong correlation with head gasket failure including manny repeat failures when the EGR system was not cleaned when the head gasket was replaced.

Thanks in advance..
So the Fel Pro gasket is the best one? Would you or would you not use another OEM Toyota gasket? And should I use new headbolts ?
This issue seems to be prevalent in the 2AR-FE as well. My mother's 2015 Camry (Very well maintained & not beat on) without warning, it blew the head gasket at 38k mi. The only DTC's were P0302 & 303. (Important for her case study). The Local Toyota dealership ran their diagnostics and maintenance history, and pushed back trying to deny the manufacturer warranty claim for the "H.G" due to in her maint. history, she had got her oil changed a few weeks before (Late June) by an "express" style oil change franchise, and they used 5w-20syn. Toyota tried to deny the claim because on the oil fill cap it says 0w-20syn. 😂 Too bad it states in her camrys owners manual, that during spring/summer months, it's 100% safe and suitable for the 2AR-Fe. I stepped in on her behalf, as a certified Auto mechanic, my first question for the head tech of the warranty & service department was, "were there any VVT, cam/crank correlation, EOP DTC's current or stored?" - No. "Was there any coolant temp. related DTC's?" - No.........😬 "So just the 302 - 303 misfire's?" - Yes.......😳 Umm you might want to contact your superiors at Toyota global warranty center. 🤔 - 20mins later he came back saying, "Her claim was approved finding her clear of any cause of failure & set her up with a free loaner car until her Camry was repaired. Nobody is going to rip my mom off on vehicle repairs, damn sure not the dealership! 80k since the repair and it's been ok. Now just yesterday it set a P0420 🥴 fml😅
Which generation of Prius have less chance of head gasket failure?
Do you recommend frequent replacements of head gasket? If yes after how many miles?
It shouldnt be a frequent occurence if it is then there is something wrong or gaskets installed are very bad.
If its designed well it should last for at least 300-350k miles.
In Prius main problems are both design (too narrow gaos between cylinders and open deck design) and hybrid system which doesnt let the engine fully heat up and keep the temperature.
You are the man and a true resource, homie. Thanks so much.

Some people blame the electric water pump or a clog egr cooler and intake manifold.

@@paulgoudfrooij6561 Mine has almost 107,000 miles on it, got it with 100,000 miles for $6,500
@@hedgehogthesonic3181 ok - that’s too early for this issue to show up anyway. It typically shows up at 150,000 to 180,000 miles. But I have indeed heard that the 1.5 l engine in the Prius C is less susceptible to this problem than the 1.8 l in the regular Prius.
@@paulgoudfrooij6561 I have tried to search online about this issue on the Prius C engine, have not been able to find any so far
Having this EXACT problem! Thanks soo much!!
Best explanation ever! Is there someone you guys can recommend around Greenville SC?
Makes sense. I'm an uber driver and have the car running 24/7. Don't shut it off when going into stores, end up sleeping in my car 50% of the time. (Because too tired to get home). I drive about 15 hours a day. Got 300k out of my prius on original gasket which is impressive.
Probably going to use a sealer. Idk maybe I'll change the gasket. It's got 300k miles on it, might as well try the sealer, and if it don't work, get a new engine.
Jesus dude, that's no way to live a life. But I'm glad you were able to get that much use out of the first head gasket..
Does change oil frequently help prius engine head gaskets last longer ?
I would suggest using the Bars head gasket sealer before it starts to leak and leave it in. I posted a comment today about using the Bars on my prius.
How many miles will the gasket last on average ?
Thank you, very informative, like others have said, your way with words easy and simple to understand, thank you again 😄
Im learning so much from these guys
Great information, what head gasket brand do you recommend? Oem Toyota? Or Felpro?
do you install felpro or O.E. head gaskets on prius engines ?
Thanks so much for the great videos! I have a blown head gasket on my 2010 Toyota prius (milk in the oil) and you videos have given me the knowledge to talk intelligently interview mechanics for a replacement gasket. I wish I lived near your service areas.
very well explained 👏. I work for lyft with my prius should i replace the head gasket now or wait until misfire? currently milege 125k Thank's
Yesssss
@@gasketmasters thank you for your response. but i didn't get it should i replace it now? thanks again.
Don’t replace it unless you have misfire symptoms, my 2012 Prius just went over 200k without any HG symptoms. Dealer replaced the EGR @ 146k miles because it was a recalled, I did replaced the water pump and PVC valve @185k miles just for preventative maintenance.
So I'm getting all this symptoms, but no coolant loss, and compression is even across the cylinders. 150/155/160. Started with P0300, P0301 P0303.
New egr valve, recent PCV valve change. Now intermittent rattling at lower rpms. Cylinder 2 misfire but not enough to throw CEL.
2013 prius 274k miles
How do I make sure it's a Headgasket failure without going to the shop???
Go to your nearest auto parts store. Rent a “combustion leak tester”. It’s a plastic tube that has a cap with a hole on top to fit a suction cup or rubber hose, and a cone with a small hole in it on the other. Pour a small amount of the included fluid in the tube and cap it off. Remove the reservoir cap and put the cone on it. Have an assistant start the car. (If the car is in ready mode, have the assistant give it just enough gas pedal to kick the car on, or turn the heater on high temp, high fan). Draw a vacuum on the tube and watch the fluid color. If it changes, the head gasket is blown.
What solved the rattling in your prius engine?
Helped my son replace his Prius head gasket a few weeks ago, it is running fine now. However, we had called a few shops to get a quote, but none of them wanted to do it on a 2012 Prius, the one shop that gave an initial quote of around $3500, then asked how many miles, when we said 175k, they then said, no they wouldn't do it, too high of mileage. Something about liability. What is up with that?
Would you say Hybrid cars are not worth buying because this problem?
thanks for the vid. my car is a 2013 hybrid toyota 3rd gen i noticed a high coolant consumption on engine with poor engine power. but no oil consumption . is this could be a sign of a failure head gasket ?
Yep. Definitely
Guys are just professionals number one !!!
Hi!
Im having issues with my 2011 prius I just bought it recently it has only 134k miles and I just got back from a vacations trip it was like 3 thousands miles round trip and I put like 4 quarts of oil total and I noticed the car has like black stains I. The rear bumper and rear door like if the car was smoking or something. Pls help any idea what it can be? I just replace the PVC valve and still burning oil like crazy . pls help! Do I need to replace head gasket? That's what I'm thinking but I'm not sure help!!!!!!!!
Clean your EGR
Thanks for the info brother
I wish I would have seen this video 2 years ago. My 2010 Prius died after 196k miles. It would do the rattle a lot at startup. At the time, nobody really knew what it was. It steadily lost power, clicking in the engine, and noticed coolant getting low all the time. When I took it to the dealer, they took the info, and wouldn't actually do a pressure test without a big fee and NEVER mentioned head gasket. I ended up buying another car now, but still have the Prius. I may try to have another engine put into it, but then again, the Hybrid battery and Catalytic converter probably will only have 100k left anyway, so might not be worth it.
Had I replaced the head gasket before the piston clicking, then it would have been a save. Too late now.
We ship rebuilt engines.
@@gasketmasters how much on a rebuilt engine. Also the hybrid battery?
