'Old Skool' method was to disconnect the battery, fill the engine TO THE BRIM with diesel, and leave it soaking overnight. Drain completely, fresh oil, run for 30 minutes then fresh oil + filter...
Did this with Castrol degreaser on a friend's old truck. Like 5 gallons. Left it full while he went out of town for a few days. Drained it when he got back home, put cheap oil in with a new filter, started it, let it run for a few minutes, check to make sure the oil wasn't completely getting destroyed by the degreaser, drove it around for about 10 minutes, drained the oil, put new cheap oil in with a quart of Rislone oil additive (basically 5W-30 oil with some really heavy detergents). Change the oil and filter again in 1000 me, came out totally black, and his oil pressure problems were gone, the valve train noise was gone, and under the valve covers was really surprisingly clean. Obviously this is the kind of thing you would only do if the next step would be to rebuild the engine or junk the car.
An old mechanic told me years ago that it takes a long time for the sludge to get there, and it needs to take a long time to get it off. He was right. I learned the hard way more than once.
@@RayleighCriterion They work better for preventative maintenance. Oil and basic flushes barely scratch the surface on a sludged engines. The BG products actually work and are supported by the manufacturers. I've been able to unstick rings, clean out cam phasers and eliminate oil starvation knock with it. Saving an engine for a couple hundred bucks seems like a good deal to me.

I had an old Honda Prelude in the 90s that was given to me by an elderly family member the engine was sludged up even worst than your engine , it only has 40 something thousand miles, I used Wynns engine flush and drove around in it for a week I had nothing to lose after a week I drained it and that engine and sump looked brand new inside the valve gear looked spotless. Changed the rocker gasket and put new oil in it , changed the oil a month later and it was still cleanish. TBH with a dirt engine I dont think 20 minutes is long enough for that engine flush to do its best you need to drive the car around to get the stuff through all the passageways in the modern engine and allow it to cycle through different pressure cycles with fast and slow driving. I had the car for 8 years after that and it ran beautifully with regular oil changes of 3-4000 miles I think 6000 miles its to high. Even today I get my oil changed at 4000 miles and I always use Castrol because I trust it car is 4 years old now another Honda.
Nah definitely don't drive around with an engine flush. Not designed for that at all and will most likely cause damage. Then again if you've let your engine get that sludged up it would hardly matter I guess.

Engine flush dilutes the oil and is not safe to drive. There are chemicals tha evaporate, so the longer you drive the more dirt may stay compared to draining the oil after 10 min
👋 from Melbourne, Australia 🇦🇺. A man of many talents is Gaz. Even Fendy wanted in on the action. That Engine was disgusting. My Dad died 24 years ago, but he was an Engineer & a Motor Mechanic. My Dad had to retire early because of his health. But he started a business from home as a mechanic. He then was able to work when he was able. He also worked as a consultant for the police & for insurance companies, looking over cars etc after car accidents. I grew up around cars & engines. Us kids even helped him put the second story on our house. We were never put in any danger. But I was always more like my Dad. I'm a woman & I can change tyres, spark plugs & air filters. And check & fill all the different liquids that go in a car. I can't drive a manual car anymore, as I'm in a wheelchair & have to drive with hand controls.
You'd be much better to use a flushing oil. Comma make one. Run your engine up to temp, drop the oil and fill it back up with nice clean flushing oil. Run it for the specified time and drop it out. You'll notice that it's darker and dirtier than the old oil. Flushing oil definitely removes a lot more crap from the engine than an oil additive. No matter how good it is. When you do your new oil and filter, add ZX1 to the oil. You'll be glad you did.
I thought I'd be bored watching a video about a car engine, but this was really interesting! I'm looking forward to seeing the sludge(less?) results in the next one. Good job Gaz! 😊
How very odd I was literally looking at this product this morning and seeing weather or not it works on youtube😂 all American reviews so I'm glad you have decided to do it! 👍🏻

I use a oil flush every 2nd oil change. Use a high detergent Diesel oil every 2nd oil change. Have done this for years (including on a 1187rwkw F6 Tornado ute), and never had any sludge issues, and in at least 2 2nd hand cars i have bought- cleaned up the sludge deposits with 5,000km oil & filter changes
Looks better mate after the flushes. Personally, I wouldn’t have bothered if it was running well. I’ve had all Japanese motors for a long time now mainly Suzuki and Subaru. Ridiculously reliable motors and they actually manufacture them to be badly maintained. The difference is that Euro manufacturers make engines that they expect you to maintain really well. I had an Impreza that I bought with 50k miles on it and repped in it doing on average 200 miles a day. Sold it with 194k on it. It had a couple of oil changes and a new filter every now and then when I could be bothered. I just topped it up with Castrol Edge every now and then. Bullet proof Japanese engines if you use a good quality oil.
Hi Gaz, I loved watching this I spent alot of time with my step and learnt alot with motors. I didn't think it made alot of difference with the oil changes. Time will tell, with another go. Can't wait for xxx
Your thought process with the thicker oil makes sense on the one hand, but on the other hand a thinner oil will get into the narrow parts of the engine better, and you have a higher flow rate with thinner oil basically picking up the sludge at a faster rate since the flow has a higher viscosity. So i would advise a thinner oil.
Check your cooling system, coolant and thermostat while your at it and pay attetion to gauges aswell. Engines can sludge up due to overheating, this one might just be case of a missed oil change or two though
The New Wonder Oil is Valvoline Restore and Protect. The Oil Geek did a review and apparently it works. No flush, just add the oil and drive. After a few oil changes the engine will be clean. I would change oil a bit early because some people have found the cleaning so good that the filter gets clogged. Good show Giz.
Another old school method is to do a normal oil change, but go 1 qt, less of motor oil and put 1 qt of dextron, 3 transmission fluid in your motor oil, you can go one weight heavier with your motoil, so that the transmission fluid doesn't thin it out too much. The transmission fluid is extremely heavy on detergents. And we'll clean the engine very well. This can be a long-term thing. You run the motor oil/ transmission fluid for the entire life of the normal oil cycle. Change the oil out. Put normal oil in with normal amount. Then the next time you change it, do the transmission one again. Do it every other oil change. Putting trans 1 quart of transmission fluid. In with the motor oil, your engine will be clean. After about 5, all changes, and even varnish will be gone.
Some years ago I bought a 200,000km bmw 535i with the M30 engine . As it arrived the visible valve and cam train whilst not as bad as the Rav 4, were visibly bronze in colour with gum deposits. After about 3 years of an engine flush and oil change every 5,000 kms the view of the cams and valves was of that of a brand new car. All silver!
It doesn't seem that it did a whole lot, but maybe that is a good thing. With all that varnish buildup, if it becomes loose all at once, it will not dissolve and it could clog the oil pan pickup tube. Ask me how I know it. Change the oil at half the intervals and you will see a noticeable difference in 15-20k km
I've done that n just carry a few oil filters with you. I added a half gallon of diesel fuel n let it ilde 10 min.then drained it for ever letting it stop dripping.then just keep changing the oil n filters
Another way to clean that engine would be drain the oil and fill the crank case all the way up to the oil cap fill with diesel, fuel, or kerosene, and all out to soak for several days. Drain it and then do a proper filter change and fresh oil. I would repeat the process about every 500 miles three or four times. Whoever owned that car did not believe in fresh oil.
Great video. I swear by that stuff. Whenever I would buy a new used car, I would use this on the first three oil changes. This restored 2 Mercedes engines. For this car, I would have first added a quart of transmission fluid to remove the large bits. Changed the oil then run the flush.
You hit the nail on the head when you said flushing sometimes should be avoided. I used seafoam on a Ford Taurus SHO, and after that it leaked oil like the Titanic.
This video is a good reminder to me as to why I have several different types of surgical forceps, including one that is a long reach variety, in my tool cart. Thanks for the video.
I use Lucas engine oil treatment to get rid of a leak and it worked it's a miracle. I had to put it in about three times every oil change to get it to go to work but it did it
Hi unfortunately my partner died in Dec and he used to do all the maintenance on our cars, now I am trying to maintaine them, I know what you mean about trying to find information about different problems lol it's very difficult, I have a Toyota Avensis which also being an older model needs a bit more TLC, it looked a slight bit better with the flushes but I think red diesel may help, also I have been told that Toyotas love frequent oil changes, maybe more than other makes, it seems they can fail really quick if left with dirty oil, someone has obviously not looked after your motor in the past, hope you get it up and running again, you seem to know what your doing, which is a bonus lol good luck xx
It's due to the PCV system failing on some Toyota models. People often overlook them and just change the oil and not the PCV valve also. It's fairly cheap and easy to do ✌️
You want to use straight Kerosene in the crank case and keep flushing until it runs clear then I'd recommend using high mileage oil and a high mileage STP.
Good job gaz, I think the liquid molly did clean it up a bit, that sludge stuff should hopefully will clean it up a bit more, but don't clean it up too much because you could get leaky seals. Oh by the way can I bring our car round to do the oil change the car lift is great 😂 enjoyed watching this and looking forward to the sludge remover nice to see what you get up to, but I do enjoy the camping too x
Thanks for this video, I was considering this product on a old junk project i have. The vehicle is not as bad as this toyota, has some oil urn stains, but not blobs of debris. I may still give it a shot and see what it does.
Great video. Another way is try say the engine needs 7 quarts of oil. 4 quarts of heavy oil. 2 quarts of diesel and 1 quart of transmission oil. Run it for about an hour but what the oil pressure gauge, then drain. That has helped.
Ive seen kerosene used mixed with the oil....engine IDLE only.. 50/50 Use thicker oil 15W40 or 20W50 .... For 30/45. Mins. Then drain and fill Again with oil kerosene again... Ive seen severely sludged junkyard engines cleaned by this message...piston rings and valves were gummed up and it free'd everything loose.. Just a thought to try. Diesel also works as a cleaner mixed with oil , i even seen Varsol used as a cleaner.
@@rodsvintagesxschannel.3095 I’ve heard even start it with only kerosene/diesel for 30 seconds then drain and do a 50/50 idle until it gets to temp leave it for 10 minutes then fill it with oil and drive it for a week and do a normal oil change
@@h0udinl id never got straight kerosene or diesel..its lubricity is insufficient...still need lubrication. I worked in a garage for several yrs under seasoned mechanics.. I was always told nothing cleaned dirty parts as gd as Varsol or Kerosene...used in part with oil. I also knew a gent whom tried WD40 mixed with SAE 30 oil to flush/clean junkyard engines to make " budget runners " and he was quite sucessful with it.
I did the injector seals in my 1.9 pd tdi a couple of months ago, everything under the rocker cover was mint. Frequent oil changes that’s why 👍🏼 The engine in this video has been neglected. I don’t think I’ve ever seen one of these cars about.
I have to say, I've gained a whole new appreciation of your skill level! Here I was thinking you were just another British tree hugging git and I come to find out that you have grease and oil in your blood! Way to go!
Ahh Twin cam . looks like she is running a good mixture ( carbon lumps /deposits ) Oil breather pipes maybe sludged up also Gaz . Maybe a new air filter would be a good shout , if its not already been done , she looks good underneath Gaz . 👍
Yeah 3s and 5s(successor) are known sludge mobiles. Youll wanna keep oil changes more frequent than normal for longevity, otherwsie their known to be very durable and relaible engines
Liqui Moly stuff is all quality, imo. I've used a lot of their products and was very satisfied. With the engine flush you definitely need to drop the pan, after, and clean your pickup tube. I've used it preventatively and there was a lot of gunk on the pickup tube after. A friend used it to get his piston rings loose on a Honda HRV, worked well.
do an oil change, and substitute 1 quart of oil with a quart of automatic transmission fluid. Drive it 1000 miles or so. Pay particular attention to the oil pressure though. A real dirty engine might get the oil pump filter screen get clogged up when all the crud gets knocked loose. Do this for a couple oil changes. Drive a little longer with each progress. After the 3rd oil change, it should be cleaned up pretty well. The high detergent in the ATF works great to loosen those deposits. Probably a lot cheaper than the product used in this video.
In the States it's Valvoline restore and protect, the petrol compatible version has been in development for years, hopefully it's available in the UK or will be soon, great video and good luck
Thanks for the interesting vid mate. I went down The rabbit hole the last 3 weeks for my car as well lol As for the cleaning it looked pretty good, going forward using new synthetic oil every 5k should clean out your engine even better
@@andreaphillian3947 BMW says I can go 10,000 miles on oil which is an absolute joke. I change it annually but I only drive that car maybe 3-4,00mi a year (and make sure I get it up to operating temperature every time). Mad that they did away with the dipstick, it's a sensor in the pan that fails.
Brother, honestly you have chosen the very right product. Liqui Moly works great. However, the buildup on your engine is very strong. Just put fresh oil in it. Drive normally as you have flashed 2X time. The flushing detergents are still there. It will gradually breakdown those particles and in the next oil change, you will see a noticeable change.
Honestly, as a woman…I wondered if this “would” be interesting? And it really “WAS” also kind of a learning experience! And that handsome face helps keeps me paying attention 😊 be blessed Gaz❣️🙏
Ive been a car guy all of my 60+ years and Ive never seen a bottle of crap actually clean the inside of an engine. I can tell you that I have seen an impressive transformation of a crap filled engine turned pretty clean by simply changing the oil VERY OFTEN and just drive the vehicle a lot. Long drives will heat up and soften the build up and the new oil filter captures what it can. I used cheap oil and cheap oil filters and simply changed the oil every couple weekends until you didnt see all the grime. In your case, you have gotten ahead of the game by cleaning the rocker cover and oil pan out. Look for an oil with DETERGENT and 10w-30 is fine. When the dipstick looks like the engine has clean oil in it after running a few miles, you are done. SeaFoam... I think it works best when you suck it into the intake via a vacuum port while the engine is running. She will want to kick and die so keep the engine running and suck in slowly about 1/3 of the can. Shut the engine off and let it sit for 15 minutes and then start it up and rev the engine until it stops smoking. And it WILL SMOKE! Then it will idle like a baby! Best of luck!
Used this LiquiMoly flush on an old BMW X5 I bought last year, prior to doing my first oil change. The drained oil was absolutely black as night where prior to adding the flush juice it was a dark brown. I didn't pop the valve cover to look but the engine (M54 I-6) ran more quietly afterwards despite nearly 200,000 miles.
I've used sea foam like the day before I changed the oil. Pour it in, drive like normal. The oil seemed thinner and definitely dirtier when I drained it. That being said, I just switched to synthetic since then and stopped with the sea foam. I think solvents are bad for bearings.
use Ezi Engine flash, it works well in Libya, the environment here is desert and we love Toyota cars, both new and old, and we found the above product to be very excellent, I advise you to try it, my regards 👍
You want to change the oil filter again now Gaz. If any crap came off the internals of the engine they will be in there. That's a nice looking lift you have.
@@GrizzlyGaz - Instead of a 15w40 next time use a 5w30 API SN like Mannol or Champiol which is dirty cheap. They have more cleaning additives and this circulates better than a 15w40. Start the first flush with a 5w30 fill. Grtz and thanks from Belgium.
@@GrizzlyGaz They're right, you should use the right weight of oil, your thinking was wrong, oil already clings to all of the surfaces, this only makes it harder for the engine to pump the same volume of oil through the system.
Grizzly G, give Valvoline Restore and protect a try. I used it in 3 different Japanese vehicles from June 2024 and it has made a significant difference in cleaning up the engines. The difference was felt in the first 100 miles of driving and I 😁 changed out the filter after 500 miles. All 3 vehicles (2 Lexus, 1 Subaru) had increased power response, quieter idling and better mileage within the first month of use.
I have use it it works nice, but I found out if you drain out old oil put 50/50 mix oil & diesel runs it for 1 hr drain and then use moly you get a much better flush and clean
I did this on my Range Rover with 90k miles, and it took 5 flushes in a row to get the oil coming out clean. I have a video of it I’ll post on my channel soon, but I used the same stuff you have here so if anyone is wondering, it’s going to take a bunch of these in a row to clean sludge like that. Some Russian guy did a video similar and he took like 8 flushes on his Lada
You can see the difference, but the main difference is not going to be noticeable, which is in the lubrication ducts and in the hottest lubrication points where they will clean that sludge and the oil will be able to pass through and lubricate the sensitive parts. In addition, that sludge will be removed as the oil changes are carried out, as the manufacturer says, because the new oil has properties such as detergent properties that are mixed with the sludge and dragged along with each change.
Another old school way is about 500 miles from oil change time add 1 qrt of ATF to the crank case and drive the final 500 miles then do your oil change keeps engine super clean! I always remove about 1 qrt to avoid over filling.
Whenever i flush, i always alternate the revs quite a lot. Even had a drive not thrashing it, but you cant expect miracles. It needs a flushing oil or some atf works too
I wonder what would happen if you just filled the engine up with petrol all the way to the top of the valves and let it sit overnight. It sure cleaned up the valve cover pretty well. I did that to an old lawnmower and it worked great but not sure if a car would suffer some sort of damage from it.
I was going to say you’ll need to drive it with the cleaner, in other words have it in there longer. Definitely like the gunk remover that you mention at the end 👍
You should try valvoline restore and protect after your flush and see if it continues the cleaning. But I'd recommend you monitor the oil pressure and replace the filter around 600 or 800 miles into the first oil change.
Some deposits are not avoidable, due to the fuel addtives in gasonline, especially the MMT. Oil flush is mostly used for free up oil rings if your engine burns lots of oil due to seized oil rings. If your eninge have no performance issue , or not losing too much oil, then just do oil change more often, will help this issue(with good oil for sure).
The only way to clean that engine is slowly, I'd use a matching viscosity diesel oil and change it every 2k max miles along with filter. There is a great issue of moving lumps around when you start using an engine flush on an engine in that condition.
Gidday mate I can honestly say I'm in me early early 40s an this year was the first time I ever did a oil change on me old Nissan Venette , I'm shocking like that.. I'll just keep driving and driving 😂, Yours looks really good after the flushes and cleaning cause holy moly cotton candy it was thick looking aye. Hopefully the next stuff is even better.
I had an engine like this. A product similar. I’m interested in a follow up after driving. 3month after cleaning, the engine started knocking. The oil passages were clogged up with chunks of sludge. Engine had to be hot tank cleaned twice before rebuild could start.
For new and up coming mechanics and fitters. ALWAYS lube the filter o-ring with CLEAN engine oil, and NOT with the old used engine oil. Reason being is that the old engine is contaminated with carbon deposits, and that makes it very difficult to remove the filters next time around.
@@juleesadventures7925 it's running sweet dude 👌 Changed the spark plugs, ignition leads and PCV valve. Now it's a lot more responsive and smoother idle. Gonna see if it's affected the fuel consumption in any way as before it was really thirsty
An alternative option is to drop a liter of oil out; refill with a liter of diesel and let it idle for a while... I wouldn't go for any spirited drives, as the oil with be significantly thinner... but idling/low RPM/load is usually fine. You may get a little bit of smoke from the exhaust temporarily, as oil will probably leak past some seals (due to the reduced viscosity). Then dump the oil and re-fill. Consider doing an earlier oil change as well the next time, just to remove any residual diesel.
I used to use flushing oil run the engine on low Rev's for a few hour's then drop it out then run it again with new flushing oil then once I was happy new engine oil and filters that engine was clean compared to some of the engines I use to do the flushing oil we used to use was a mixture of diesel fuel and a heavy motor oil mixed together always work great once you got the mix right.
A trick i learned from an old timer at my dealer is with every oil change put about 4 oz of ATF fluid in with your oil. ATF is just straight detergent. After about 10k miles and 2 oil changes my valve cover and valve trains had been cleaned of almost 300k miles worth of gunk. Its simple, effective and does zero damage whatsoever to the engine. I'd Highly recommend for those who aren't comfortable taking an engine apart to give it a try.
@@fallenplays5849 Please refrain from spreading misinformation. That’s modern oil chemistries working for you. ATF is NOT just straight detergent. Today’s motor oils have many times more detergent in them than ATF. The icing on the cake here is that detergents help keep sludge suspended in the oil. The scrubbing action comes from high quality base stocks in the oil. It would have actually been less work for you to not spread false information than to get on here and type out some old wives tale.
Need to get her proper hot before doing flushes. Go for quick drive and work her hard then add flush and let her idle. The extra build up on the valve train isn’t really an issue the clean oil will clear out the bearing surfaces. Just gotta remember these products are for maintenance use not a magic fix years of neglect cure. Keep up the great work Gaz 👍🏻
Grizzly. I spent a year looking for a rust free older van. Almost impossible in Michigan. And here is how I got duped. First off the van 1995, Ford 100% rust free everywhere clean clean clean. Was smitten. When it comes to checking the transmission fluid, he pulled the dipstick out for me showed me the end. Fluid was nice and red. Paid top dollar for the van. Got home drove fine. Looking at all over check the transmission again ! Wiped the end of the dipstick. And it was a little too red. After looking more he painted the end of the dipstick Red where the oil line was. 300 miles later was putting a new transmission in. Just thought I would share. I’ve never seen that before.
kerosine or diesel works better for thick sludge also when you do an oil change drop a bit of diesel down into the engine wiht the plug out to try and flush some sludge
Well done, I like how you performed the test. I guess you aren't all satisfied with the result, I wouldn't be. Therefor, I think you should run the sludge remover aswell before puttning any expensive oil in or new gasket for the valvecover. Cheers from Sweden 👍

How very odd I was literally looking at this product this morning and seeing weather or not it works on youtube😂 all American reviews so I'm glad you have decided to do it! 👍🏻
Hope this helps
@@GrizzlyGazhiya gaz, I've got a toyota 3 lyrics turbo diesel reguis, great to drive , but its a import so have to wait for parts from toyota ,when I cannot get them from euro parts , just a message to let you know about euro parts they are very reasonable dont want to use the word cheap , may see you out and about as I camp about a bit in it , and live in lancashire, love to fendy and you and your family, take care it does look better your engine😊
I use a oil flush every 2nd oil change.
Use a high detergent Diesel oil every 2nd oil change.
Have done this for years (including on a 1187rwkw F6 Tornado ute), and never had any sludge issues, and in at least 2 2nd hand cars i have bought- cleaned up the sludge deposits with 5,000km oil & filter changes
You sound like someone that will appreciate Valvoline Restore. And Valvoline Restore and Protect.
Looks better mate after the flushes. Personally, I wouldn’t have bothered if it was running well. I’ve had all Japanese motors for a long time now mainly Suzuki and Subaru. Ridiculously reliable motors and they actually manufacture them to be badly maintained. The difference is that Euro manufacturers make engines that they expect you to maintain really well. I had an Impreza that I bought with 50k miles on it and repped in it doing on average 200 miles a day. Sold it with 194k on it. It had a couple of oil changes and a new filter every now and then when I could be bothered. I just topped it up with Castrol Edge every now and then. Bullet proof Japanese engines if you use a good quality oil.
It was so clogged it was even taking oik

Hi Gaz, I loved watching this I spent alot of time with my step and learnt alot with motors. I didn't think it made alot of difference with the oil changes. Time will tell, with another go. Can't wait for xxx
It looked cleaner to me Gaz great job man
Your thought process with the thicker oil makes sense on the one hand, but on the other hand a thinner oil will get into the narrow parts of the engine better, and you have a higher flow rate with thinner oil basically picking up the sludge at a faster rate since the flow has a higher viscosity. So i would advise a thinner oil.
Check your cooling system, coolant and thermostat while your at it and pay attetion to gauges aswell. Engines can sludge up due to overheating, this one might just be case of a missed oil change or two though
PCV valve failure
@@GrizzlyGazoh wow, forgot to mention but this is like the second most known problem on this engine series
Short trips
The New Wonder Oil is Valvoline Restore and Protect.
The Oil Geek did a review and apparently it works.
No flush, just add the oil and drive. After a few oil changes the engine will be clean.
I would change oil a bit early because some people have found the cleaning so good that the filter gets clogged.
Good show Giz.
Definitely good results. I'd probably change the filter every 1000 miles. Change the oil every 2000 miles. It really gets the gunk out.
Another old school method is to do a normal oil change, but go 1 qt, less of motor oil and put 1 qt of dextron, 3 transmission fluid in your motor oil, you can go one weight heavier with your motoil, so that the transmission fluid doesn't thin it out too much. The transmission fluid is extremely heavy on detergents. And we'll clean the engine very well. This can be a long-term thing. You run the motor oil/ transmission fluid for the entire life of the normal oil cycle. Change the oil out. Put normal oil in with normal amount. Then the next time you change it, do the transmission one again. Do it every other oil change. Putting trans 1 quart of transmission fluid. In with the motor oil, your engine will be clean. After about 5, all changes, and even varnish will be gone.
@@SuperGokuSon motor oil has way more detergente than atf
Some years ago I bought a 200,000km bmw 535i with the M30 engine . As it arrived the visible valve and cam train whilst not as bad as the Rav 4, were visibly bronze in colour with gum deposits. After about 3 years of an engine flush and oil change every 5,000 kms the view of the cams and valves was of that of a brand new car. All silver!
Nice!
It doesn't seem that it did a whole lot, but maybe that is a good thing. With all that varnish buildup, if it becomes loose all at once, it will not dissolve and it could clog the oil pan pickup tube. Ask me how I know it.
Change the oil at half the intervals and you will see a noticeable difference in 15-20k km
I've done that n just carry a few oil filters with you. I added a half gallon of diesel fuel n let it ilde 10 min.then drained it for ever letting it stop dripping.then just keep changing the oil n filters
Looooving this video! My camping car is a 2004 Subaru Forester. She's a wee ripper! I'm always keen to learn more about engine maintenance. Thankyou 🤩
Valvoline restore and protect worked wonders for my 2.0 duratec in my 2006 ford focus zx3
1/2 quart on trans fluid in with the next three oil changes will clean it up nicely.
Thanks!
No problem!
Another way to clean that engine would be drain the oil and fill the crank case all the way up to the oil cap fill with diesel, fuel, or kerosene, and all out to soak for several days. Drain it and then do a proper filter change and fresh oil. I would repeat the process about every 500 miles three or four times. Whoever owned that car did not believe in fresh oil.
Great video. I swear by that stuff. Whenever I would buy a new used car, I would use this on the first three oil changes. This restored 2 Mercedes engines. For this car, I would have first added a quart of transmission fluid to remove the large bits. Changed the oil then run the flush.
A man of many talents 😂 well done Gaz x
You hit the nail on the head when you said flushing sometimes should be avoided. I used seafoam on a Ford Taurus SHO, and after that it leaked oil like the Titanic.
Why though?!
How old, and were the gaskets the originals?
This video is a good reminder to me as to why I have several different types of surgical forceps, including one that is a long reach variety, in my tool cart. Thanks for the video.
I use Lucas engine oil treatment to get rid of a leak and it worked it's a miracle. I had to put it in about three times every oil change to get it to go to work but it did it
Thanks
Hi unfortunately my partner died in Dec and he used to do all the maintenance on our cars, now I am trying to maintaine them, I know what you mean about trying to find information about different problems lol it's very difficult, I have a Toyota Avensis which also being an older model needs a bit more TLC, it looked a slight bit better with the flushes but I think red diesel may help, also I have been told that Toyotas love frequent oil changes, maybe more than other makes, it seems they can fail really quick if left with dirty oil, someone has obviously not looked after your motor in the past, hope you get it up and running again, you seem to know what your doing, which is a bonus lol good luck xx
No problem 🫡
It's due to the PCV system failing on some Toyota models. People often overlook them and just change the oil and not the PCV valve also. It's fairly cheap and easy to do ✌️
Thank you xx
The after looks way better then the before good job Gaz!!
Hi Gaz, I gave my 2008 CRV an engine flush after the VVT was playing up, two years ago, it’s been awesome ever since 👍
You want to use straight Kerosene in the crank case and keep flushing until it runs clear then I'd recommend using high mileage oil and a high mileage STP.
Take it for a good run maybe 50 miles. If the oils black, change it again. You’ll win in the end. Good video. 👏🏻👏🏻👏🏻👏🏻
Good job gaz, I think the liquid molly did clean it up a bit, that sludge stuff should hopefully will clean it up a bit more, but don't clean it up too much because you could get leaky seals. Oh by the way can I bring our car round to do the oil change the car lift is great 😂 enjoyed watching this and looking forward to the sludge remover nice to see what you get up to, but I do enjoy the camping too x
Thanks for this video, I was considering this product on a old junk project i have. The vehicle is not as bad as this toyota, has some oil urn stains, but not blobs of debris. I may still give it a shot and see what it does.
Great video.
Another way is try say the engine needs 7 quarts of oil.
4 quarts of heavy oil. 2 quarts of diesel and 1 quart of transmission oil.
Run it for about an hour but what the oil pressure gauge, then drain.
That has helped.
Ive seen kerosene used mixed with the oil....engine IDLE only.. 50/50
Use thicker oil 15W40 or 20W50 .... For 30/45. Mins. Then drain and fill
Again with oil kerosene again... Ive seen severely sludged junkyard engines cleaned by this message...piston rings and valves were gummed up and it free'd everything loose.. Just a thought to try. Diesel also works as a cleaner mixed with oil , i even seen Varsol used as a cleaner.
@@rodsvintagesxschannel.3095 I’ve heard even start it with only kerosene/diesel for 30 seconds then drain and do a 50/50 idle until it gets to temp leave it for 10 minutes then fill it with oil and drive it for a week and do a normal oil change
@@h0udinl id never got straight kerosene or diesel..its lubricity is insufficient...still need lubrication.
I worked in a garage for several yrs under seasoned mechanics.. I was always told nothing cleaned dirty parts as gd as Varsol or Kerosene...used in part with oil. I also knew a gent whom tried WD40 mixed with SAE 30 oil to flush/clean junkyard engines to make
" budget runners " and he was quite sucessful with it.
Best engine flush gaz is a pint of diesel in the oil cap run it for thirty minutes 😊
I always did this mate and it's cheep cheep I used to work on cars from a young age so I does work save a few mate hope it helps
Run it round the block drive it a bit harder to get the pressure up to the rockers to clean
I did the injector seals in my 1.9 pd tdi a couple of months ago, everything under the rocker cover was mint. Frequent oil changes that’s why 👍🏼
The engine in this video has been neglected.
I don’t think I’ve ever seen one of these cars about.
I have to say, I've gained a whole new appreciation of your skill level! Here I was thinking you were just another British tree hugging git and I come to find out that you have grease and oil in your blood! Way to go!
😎
I've just had to get rid of one, that was a two flusher 😮👍😎
Ahh Twin cam . looks like she is running a good mixture ( carbon lumps /deposits ) Oil breather pipes maybe sludged up also Gaz . Maybe a new air filter would be a good shout , if its not already been done , she looks good underneath Gaz . 👍
Yeah I've cleaned it all up in the 'sludge remover' video
Yeah 3s and 5s(successor) are known sludge mobiles. Youll wanna keep oil changes more frequent than normal for longevity, otherwsie their known to be very durable and relaible engines
Liqui Moly stuff is all quality, imo. I've used a lot of their products and was very satisfied. With the engine flush you definitely need to drop the pan, after, and clean your pickup tube. I've used it preventatively and there was a lot of gunk on the pickup tube after. A friend used it to get his piston rings loose on a Honda HRV, worked well.
do an oil change, and substitute 1 quart of oil with a quart of automatic transmission fluid. Drive it 1000 miles or so. Pay particular attention to the oil pressure though. A real dirty engine might get the oil pump filter screen get clogged up when all the crud gets knocked loose. Do this for a couple oil changes. Drive a little longer with each progress. After the 3rd oil change, it should be cleaned up pretty well.
The high detergent in the ATF works great to loosen those deposits. Probably a lot cheaper than the product used in this video.
See part 2
In the States it's Valvoline restore and protect, the petrol compatible version has been in development for years, hopefully it's available in the UK or will be soon, great video and good luck
Thanks for the interesting vid mate. I went down The rabbit hole the last 3 weeks for my car as well lol
As for the cleaning it looked pretty good, going forward using new synthetic oil every 5k should clean out your engine even better
I make sure my oil is changed every 6000 miles especially here in South Texas where we have mostly 100 plus days in the summer.
I'd go down to 5000 personally. Even when I have a hybrid that suggests 7500mi intervals
I'd highly suggest going under 5k even in that kinda heat. Heat kills engines and oil. Cold kills oil even quicker
@@aKjohn8798 I live in New York & i change my oil every year no matter how many miles i put on it
@@andreaphillian3947 1 year, 5k miles is ideal.
@@andreaphillian3947 BMW says I can go 10,000 miles on oil which is an absolute joke. I change it annually but I only drive that car maybe 3-4,00mi a year (and make sure I get it up to operating temperature every time). Mad that they did away with the dipstick, it's a sensor in the pan that fails.
Brother, honestly you have chosen the very right product. Liqui Moly works great. However, the buildup on your engine is very strong. Just put fresh oil in it. Drive normally as you have flashed 2X time. The flushing detergents are still there. It will gradually breakdown those particles and in the next oil change, you will see a noticeable change.
Loved this video Gaz, your a man of many talents. Can’t wait for the next one. Your engine looked a bit cleaner ❤

I’m a bloke and I love Gaz 😂
@@GrizzlyGaz Get a room 🤣😂🤣😂
Ive been a car guy all of my 60+ years and Ive never seen a bottle of crap actually clean the inside of an engine. I can tell you that I have seen an impressive transformation of a crap filled engine turned pretty clean by simply changing the oil VERY OFTEN and just drive the vehicle a lot. Long drives will heat up and soften the build up and the new oil filter captures what it can. I used cheap oil and cheap oil filters and simply changed the oil every couple weekends until you didnt see all the grime. In your case, you have gotten ahead of the game by cleaning the rocker cover and oil pan out. Look for an oil with DETERGENT and 10w-30 is fine. When the dipstick looks like the engine has clean oil in it after running a few miles, you are done. SeaFoam... I think it works best when you suck it into the intake via a vacuum port while the engine is running. She will want to kick and die so keep the engine running and suck in slowly about 1/3 of the can. Shut the engine off and let it sit for 15 minutes and then start it up and rev the engine until it stops smoking. And it WILL SMOKE! Then it will idle like a baby! Best of luck!
Used this LiquiMoly flush on an old BMW X5 I bought last year, prior to doing my first oil change. The drained oil was absolutely black as night where prior to adding the flush juice it was a dark brown. I didn't pop the valve cover to look but the engine (M54 I-6) ran more quietly afterwards despite nearly 200,000 miles.
@@greavous93 I agree with you 💯 percent
I've used sea foam like the day before I changed the oil. Pour it in, drive like normal. The oil seemed thinner and definitely dirtier when I drained it. That being said, I just switched to synthetic since then and stopped with the sea foam. I think solvents are bad for bearings.
use Ezi Engine flash, it works well in Libya, the environment here is desert and we love Toyota cars, both new and old, and we found the above product to be very excellent, I advise you to try it, my regards 👍
Where do usually find this oil in libya?
@@vazione5410
Every where in libya ، specialy in tripoli . In Q20 libya stores
The product made in thiland , very effective .
Do BG EPR or Dynamic Engine cleaner
You want to change the oil filter again now Gaz. If any crap came off the internals of the engine they will be in there. That's a nice looking lift you have.
I changed it with each oil change 👍
@@GrizzlyGaz - Instead of a 15w40 next time use a 5w30 API SN like Mannol or Champiol which is dirty cheap.
They have more cleaning additives and this circulates better than a 15w40.
Start the first flush with a 5w30 fill.
Grtz and thanks from Belgium.
@@laurapalmerTDGE did you watch the video? 🤣
@@laurapalmerTDGEa much better recommendation. Would be Valvoline Restore and Valvoline Restore and Protect
@@GrizzlyGaz They're right, you should use the right weight of oil, your thinking was wrong, oil already clings to all of the surfaces, this only makes it harder for the engine to pump the same volume of oil through the system.
I absolutely love your videos. You make me laugh, love fendi too. Good job on that car. Looking forward to next video. Take care hun.
Hi Gaz you did a great job on your motor it was very interesting to watch your a man of Many skills 😊
Grizzly G, give Valvoline Restore and protect a try. I used it in 3 different Japanese vehicles from June 2024 and it has made a significant difference in cleaning up the engines. The difference was felt in the first 100 miles of driving and I 😁 changed out the filter after 500 miles. All 3 vehicles (2 Lexus, 1 Subaru) had increased power response, quieter idling and better mileage within the first month of use.
Can't get it in the UK unfortunately
I have use it it works nice, but I found out if you drain out old oil put 50/50 mix oil & diesel runs it for 1 hr drain and then use moly you get a much better flush and clean
I did this on my Range Rover with 90k miles, and it took 5 flushes in a row to get the oil coming out clean. I have a video of it I’ll post on my channel soon, but I used the same stuff you have here so if anyone is wondering, it’s going to take a bunch of these in a row to clean sludge like that. Some Russian guy did a video similar and he took like 8 flushes on his Lada
You can see the difference, but the main difference is not going to be noticeable, which is in the lubrication ducts and in the hottest lubrication points where they will clean that sludge and the oil will be able to pass through and lubricate the sensitive parts.
In addition, that sludge will be removed as the oil changes are carried out, as the manufacturer says, because the new oil has properties such as detergent properties that are mixed with the sludge and dragged along with each change.
Another old school way is about 500 miles from oil change time add 1 qrt of ATF to the crank case and drive the final 500 miles then do your oil change keeps engine super clean! I always remove about 1 qrt to avoid over filling.
Befor the oil change i usually pour 1L of engine flush inside and ride the car for around 2000km. It always works and the engine is nice and clean.
Mineral oi; is the reason for all this build up inside. Toyota recomends syntetic oil for this engine.
Whenever i flush, i always alternate the revs quite a lot. Even had a drive not thrashing it, but you cant expect miracles. It needs a flushing oil or some atf works too
Used it in my e39 540 and after the flush the distribution chain etc was completely clean. Engine als ran quieter after the oil change after it.
Great job mate🙌👏 I love hard work on motors, I could watch it all day!😂❤ from NZ🇳🇿
Got another vid coming with the 'sludge remover' 🫣
I wonder what would happen if you just filled the engine up with petrol all the way to the top of the valves and let it sit overnight. It sure cleaned up the valve cover pretty well. I did that to an old lawnmower and it worked great but not sure if a car would suffer some sort of damage from it.
I was going to say you’ll need to drive it with the cleaner, in other words have it in there longer. Definitely like the gunk remover that you mention at the end 👍
You should try valvoline restore and protect after your flush and see if it continues the cleaning. But I'd recommend you monitor the oil pressure and replace the filter around 600 or 800 miles into the first oil change.
Can't get it in the UK
Some deposits are not avoidable, due to the fuel addtives in gasonline, especially the MMT. Oil flush is mostly used for free up oil rings if your engine burns lots of oil due to seized oil rings. If your eninge have no performance issue , or not losing too much oil, then just do oil change more often, will help this issue(with good oil for sure).
The only way to clean that engine is slowly, I'd use a matching viscosity diesel oil and change it every 2k max miles along with filter. There is a great issue of moving lumps around when you start using an engine flush on an engine in that condition.
Gidday mate I can honestly say I'm in me early early 40s an this year was the first time I ever did a oil change on me old Nissan Venette , I'm shocking like that..
I'll just keep driving and driving 😂,
Yours looks really good after the flushes and cleaning cause holy moly cotton candy it was thick looking aye.
Hopefully the next stuff is even better.
Great little video I’ve always used the seafoam. I don’t even know if that would touch it.
I had an engine like this. A product similar. I’m interested in a follow up after driving. 3month after cleaning, the engine started knocking. The oil passages were clogged up with chunks of sludge. Engine had to be hot tank cleaned twice before rebuild could start.
For new and up coming mechanics and fitters. ALWAYS lube the filter o-ring with CLEAN engine oil, and NOT with the old used engine oil. Reason being is that the old engine is contaminated with carbon deposits, and that makes it very difficult to remove the filters next time around.
One off the best videos you’ve made Gaz👍

@@juleesadventures7925 it's running sweet dude 👌
Changed the spark plugs, ignition leads and PCV valve. Now it's a lot more responsive and smoother idle. Gonna see if it's affected the fuel consumption in any way as before it was really thirsty
An alternative option is to drop a liter of oil out; refill with a liter of diesel and let it idle for a while... I wouldn't go for any spirited drives, as the oil with be significantly thinner... but idling/low RPM/load is usually fine. You may get a little bit of smoke from the exhaust temporarily, as oil will probably leak past some seals (due to the reduced viscosity). Then dump the oil and re-fill. Consider doing an earlier oil change as well the next time, just to remove any residual diesel.
自分でメンテナンスができるのは凄いですね！
日本車をご愛顧頂き、本当にありがとうございます 😊
I used to use flushing oil run the engine on low Rev's for a few hour's then drop it out then run it again with new flushing oil then once I was happy new engine oil and filters that engine was clean compared to some of the engines I use to do the flushing oil we used to use was a mixture of diesel fuel and a heavy motor oil mixed together always work great once you got the mix right.
BG EPR Engine performance is the best to use to clear this carbon build and sludge
It would be a good chance to try out the valvoline restore and protect. It’s a gentle clean over time and won’t over power the oil filter.
"Look at the state of it!!!", breaks me to bits every time I hear it.
A trick i learned from an old timer at my dealer is with every oil change put about 4 oz of ATF fluid in with your oil. ATF is just straight detergent. After about 10k miles and 2 oil changes my valve cover and valve trains had been cleaned of almost 300k miles worth of gunk. Its simple, effective and does zero damage whatsoever to the engine. I'd Highly recommend for those who aren't comfortable taking an engine apart to give it a try.
@@fallenplays5849 Please refrain from spreading misinformation. That’s modern oil chemistries working for you. ATF is NOT just straight detergent. Today’s motor oils have many times more detergent in them than ATF. The icing on the cake here is that detergents help keep sludge suspended in the oil. The scrubbing action comes from high quality base stocks in the oil. It would have actually been less work for you to not spread false information than to get on here and type out some old wives tale.
Try Valvoline restore& Protection oil. After 4 times oil change it would be pretty clean
Need to get her proper hot before doing flushes. Go for quick drive and work her hard then add flush and let her idle. The extra build up on the valve train isn’t really an issue the clean oil will clear out the bearing surfaces. Just gotta remember these products are for maintenance use not a magic fix years of neglect cure. Keep up the great work Gaz 👍🏻
Grizzly. I spent a year looking for a rust free older van. Almost impossible in Michigan. And here is how I got duped. First off the van 1995, Ford 100% rust free everywhere clean clean clean. Was smitten. When it comes to checking the transmission fluid, he pulled the dipstick out for me showed me the end. Fluid was nice and red. Paid top dollar for the van. Got home drove fine. Looking at all over check the transmission again ! Wiped the end of the dipstick. And it was a little too red. After looking more he painted the end of the dipstick Red where the oil line was. 300 miles later was putting a new transmission in. Just thought I would share. I’ve never seen that before.
Wtf!!! There's some naughty people about
Toluene is quite amazing for cleaning engine parts etc.
It is slight flammable and a little bit toxic, but everything is.
I’ve always driven cheap beaters.
Useing detergent oil.
I changed the oil at 2000 miles 4 changes.
Clean….
I think BG Cleaner might be the 1 you want to try. Supposed to be the strongest I think.
Or even go old school & try trans fluid & even diesel fuel.
kerosine or diesel works better for thick sludge also when you do an oil change drop a bit of diesel down into the engine wiht the plug out to try and flush some sludge
Well done, I like how you performed the test. I guess you aren't all satisfied with the result, I wouldn't be. Therefor, I think you should run the sludge remover aswell before puttning any expensive oil in or new gasket for the valvecover.
Cheers from Sweden 👍
See my other video 😉
Maybe is too much for the cleaner, but do you feel a little better run of the engine? or some change?
