Will Bar's One Seal Stop Leak fix the oil use? | Oil Burning🔥Experiments | Episode 8

[@transmissionjimmy69]

You can clean up the ring lands by loading the piston rings. Put it in second gear and go full throttle from 20 miles an hour to 60 miles an hour then let off the throttle fully do not push in the clutch and then it come back down to around 20 mph and repeat the process about four times that should definitely help. When you let off the throttle and you’re using engine braking, the vacuum pulls the rings out. This is also known as the ring seating process you will see this in your vehicle repair manual at the end of the engine rebuild section it will tell you about your first drive with the new motor.

​​@@cal48koho WELL, NOT SO. Old engine ring seating procedure DID WORK when properly done (with single grade oil straight). I checked it on an old design Ford 302 engine by carefully measuring engine compression, and it really dis seat the rings of the old type without Molybdenum. But it should work similarly on any type of rings.

[@macready0230]

Bar's Leaks has a professional version of this product called "Oil Seal Engine Oil Burning & Leak Repair", part number OS-1. It is both a stop leak and a no smoke product. It claims to address small oil leaks (1qt/month), medium oil leaks (1qt/week), large oil leaks (1qt/day), smoking from exhaust, oil consumption, harden valve stem seals, and worn valve guides. The "One Seal Stop Leak" product only addresses small oil leaks according to their chart. The FAQ on OS-1 seems to be very helpful. It claims to dissolve deposits on piston rings and work with any type of oil seal, no matter the material. The specific seal materials include nylon, nitrile, polyacrylate, silicone, viton or fluoroelastomer, and teflon. Their rear main seal product does mention neoprene... I think OS-1 would make a good prep and/or finishing product for whatever series of oil consumption steps you choose. I like the idea of skipping valve stem seal replacement and addressing worn valve guides with an additive in a high mileage vehicle.

Stop leak does not work good (or even not at all) with hyper modern rubber seals, the brown and blue ones are Viton or Neoprene seals...they are resistent. Stop seal works best with BUNA (synthetical black rubber seals = NBR) On vintage cars with NBR rubber gaskets most stop leak additives work pretty well.

Yay! 1zz-fe videos are back! My oil consumption problem got to 1 qt of oil every 200 miles. I tried all the oil additive fixes (MMO, thicker oil, etc.) didn’t work. I eventually swapped in a JDM motor. The key on these engines is run synthetic and don’t let the oil get dirty. I understand the oil return passages on the piston ring recesses are to few and too small and conventional oil gunks it up, increases friction and wears out the cylinder bores and/or piston ring prematurely / or sticks the rings. Thing is once there is so much solidified carbon to stick piston rings you can’t solve the problem with oil cleaner additives. The oil return passages are to small and too few to introduce enough solvent to clean the grooves out completely sufficiently with out removing and physically cleaning the pistons. The residual carbon you can clean out acts like a condensation nuclei for more carbon and it just builds back up again. In my case it was just easier to swap in a used JDM motor and keep the synthetic oil changes short interval (

[@TheDeadMan3848]

Dave, just found your channel and watched the whole Corolla Trilogy 😉. Love your enthusiasm. Subscribed. Might l suggest an alternative to rebuilding the entire engine (only if you can drop the oil pan without removing engine). If the pan can be dropped, remove the cylinder head, then remove the pistons with the engine installed (disconnect rod caps from below and push pistons up and out). Clean up the pistons, possibly modify the oil drain holes in the pistons, run a hone down the cylinders and install new rings. This would save a few dollars and valuable time. Don’t waste any money on machine shop work. If the above can be accomplished, (I’ve done this on hondas) you’ll more than likely get another easy 150K miles. You’re DIY Dave, don’t let the corolla win.

My cars recommended oil by manufacturer and mechanic is 10w-30 for optimal performance and fuel efficiency. The 2.0 liter 16ohv would burn the oil about a quart every 500miles as well like yours. After reading the owners manual I figured out that even though recommended oil was 10w-30, the year round temperature actually required me to use 10w-40. The car stopped burning oil and runs great.. read your owners manual and follow it's advice.

[@FamilyFriendlyDIY]

I’ll have to check, but I believe my manual said use 5W 30 in most conditions but if only driving in hot weather 10W-30 would be fine. It does have variable valve timing, so I don’t think I’m supposed to go any thicker than that. That’s good info though. Thanks for the comment!

If possible, pull the oil pan off and check for a clogged oil pickup screen right away. The knocking and rattling is caused by oil starvation. If there is alot of metallic particles in the pan, you have likely spun a bearing and oil consumption will not improve unless the engine gets rebuilt.

[@diego-jungleauto]

My car is a great oil consumer almost as yours. First I changed the oil viscosity to the thickest on the owners manual. The consumption of oil was reduced a bit. It used to consume more oil in highway so at low speeds low oil consumption. But some time ago I've noticed smoke during the first start in the morning. So, probably the valve seals were bad, but long before the morning smokes the oil consumption was remarkable. I've changed the valve stems about 2 months ago. The car doesn't smokes more during the first start and the oil seems cleaner. Unfortunately I didn't have the chance to drive it much since then, so the oil is still full. Maybe I get the road next week. I'm very interested in this saga because also believe that my problem lies in the piston rings.

[@javier.villatoro]

A simple test to rule out valve seals is to let the engine rest for a couple of days, if the valve seals are bad during that time they will leak oil in the combustion chambers, with the consumption you have it should be a good amount of oil and when you turn it on It will burn that oil in the form of smoke that will disappear after a few minutes. I know my car has bad valve seals because it does the exact same thing.

[@FamilyFriendlyDIY]

I think you’re right Javier. I’ve noticed if I let it sit for about an hour and come out and crank it when the engine is still kind of warm it does blow some smoke now. The strange thing is it hasn’t been doing that all along even though there’s been tons of oil usage all along. I think I’ve got multiple problems going on now.

[@bdtaylor1979]

The oil leaks don’t have to be external. If the seals around the spark plug wells are bad then the oil will leak into the spark plug wells and get burned out when the engine is running, especially at freeway speeds.

[@TheOverisel]

Interesting watching you try everything a DIYer can do. When those oil rings are stuck there not just stuck- they are baked in and compacted with carbon. Compacted from the combustion process over and over. Going back to 1992 we were introduced of the Saturn S. Its 4 cyl engine- SOHC and DOHC design was similar to the Japanese engines with the exception it used a timing chain. But owners discovered later in life the S motor drank oil. The oil return holes in the piston ring lands would plug causing stuck oil rings. Even with vigilant oil change intervals it eventually occurred. Saturn ran this flawed design from its debut in 1992 to the discontinuation of that engine/engines in 2002. In 2008 I tried a $25 can of a BG product in my 97 Saturn. I poured the 16oz can in the oil and ran the engine at 2500ish RPM idle for I think 20 minutes. I bought the BG product from a Saturn Dealer as this was recommended by Saturn techs. I changed the oil and filter afterward as instructed. I also had to replace the sparkplugs as they were packed and gacked with black pasty goo. I assume this to be carbon broken down by the BG and combustion. Result? My Saturn still drank the same 1 quart every 400 miles. Those pistons would need removed and cleaned (total proper rebuild actually) to eliminate consumption.

0:50 That's some nasty piston slap!.. I know this is completely anecdotal, but my friends Pajero Jr used to smoke a bit of blue smoke and went through a considerable amount of oil even driving normally. I suggested changing the oil and revving it high and drive a bit 'spirited' à la Italian tune-up since it was previously owned by an elderly that probably never revved it above 3k rpm. Anyway, some 4 weeks of 7.5k rpm driving on the weekend actually seemed to helped the oil consumption and completely removed the smoke. I've read about this in some forums, people who race their oil burners can see decrease in oil consumption. I'm assuming this can free up the rings and remove some gunk from the oil control rings. Now, I don't think its the safest thing to do on this 1zz since the piston slap is already concerning, but this is just my 2c.

[@SanProsan1993]

The 1ZZ engine has a known issue with not having enough oil return holes in the pistons. Using lower viscosity synthetic fluid (with proper intervals) will keep the return holes open. Extending Oil Change Intervals, using higher oil viscosity grade, or using conventional oil instead of synthetic only contributes more to clogging of those small oil return holes in the piston. A solution is to replace the piston rings and drill more holes in the piston, or use updated OEM pistons from Toyota, with all new piston rings as well. Aside from all this, the only product that may be able to work chemically is "HPL Engine Cleaner". But that product is so strong that one of the requirements is to change the oil filter every 1000 miles, as it just gets plugged up with gunk that is being cleaned out from the engine.

I got some information on a real aggressive piston soak. Berrymans Chem dip. You literally fill the combustion chambers with it. Let it sit over night. You cannot start the vehichle with it in the crankcase. You will want to try to suck out any excess in the chambers before doing this. Turn the engine over with either an electrical relay trick in the fuse box or just use the key. Make sure your efi fuse is pulled. Have a towel over the engine and turn if a few times to make sure any excessive Chem dip is gone. You will get a lot of carbon coming out of the tubes. Use an air hose to blow any you can out. Drain the oil. Flush the engine. You might have to flush it with oil a couple times. If you Flush it with a couple quarts, then plug the hole and fill it you should be able to start it and run it for a few minutes before draining that oil too. After that you should be able to run the new oil (2nd change) and it should be good. If your oil pressure light comes on pull your oil pressure sensor and clean it out with brake clean or throttle cleaner. Light should go off after that. This cleaner is so aggressive that it cleaned all the carbon off the top of my piston heads and I could see shiny bare metal. Before it was black. It took a good 100 miles for it to blow out all the carbon that was in the combustion chamber, and the crank. The oil control rings were what was stuck on my engine. The compression rings were in great shape, I had great compression. But even after valve seals and pcv valve it was still burning oil. I haven't had to top the oil off yet, but I will update as I go. Currently at 100 miles on the oil. When I fill up at 300 I can let you know if I've lost any.

[@nukafan2216]

(Update) My engine is a k24 Honda engine. So although it's not the same manufacturer it's similar in design, size, and it's Japanese. So very similar build quality. Honda recommends 5w-20 which is what I flushed through the engine. But after draining it scompletely and filling it up a second time. I used 10w-40. Haven't lost or burned a drop. Some might argue that this is not a good idea, but the thicker oil is counterbalanced by the 160k miles of abuse it's taken before I got it and the 5k miles I've put on it since babying it. Between the wear that's it'd gotten from the milage and age, the bearings and tolerances are looser. They're not so loose that I can't run 5w-20 on it. But it will burn if I do. It's just so thin that it's splashing in from the crankcase into the combustion chamber from the rotation of the crank and causes excess oil to be present in the combustion chamber. The thicker oil isn't throwing a code or causing more friction in the engine. It's handling it perfectly. And as I said I've yet to burn any oil in 150 miles.

LuBEGUARD oil seal with every oil change…..just make sure it’s on operating temperature when you add it to the engine compartment

[@nukafan2216]

So I am very well having the same issue believe it or not on MY 2002 C-RV. I replaced my valve seals, and pcv valve. I have some tips if you're looking for some. But I am still burning oil. I've tried oil additives and cleaners in my crankcase, and I do still have a lot of soot and carbon in my engine but it's starting to clear after 3 oil changes every 1000 miles. The only thing that has slowed the burn was a very aggressive regiment of seafoam AT oil changes, I used supertech advanced 20k mile protection 5w-20 oil, and I was using STP high milage oil treatment + stop leak. (It's a grey bottle) and it worked better than anything else that I've used (blue devil, seafoam, bars, lucas, and other stop leaks) so because of the fact that it slowed but didn't stop it. I decided to try some lucas high milage oil stabilizer. Since then I've gone from burning a quart every tank of gas, about 300-350 miles, to burning maybe a pint per tank of gas. I'm hoping that sticking with my regiment of seafoam at oil changes and a cup of diesel to the crankcase before an oil change, that it will help with my soot problem.

[@FamilyFriendlyDIY]

Good info. We have a 2001 CR-V in the family, but it doesn't burn any oil ... leaks a little though :-)

[@Techie1224]

what is the point of using 5w-20 + oil treatment ,, you know what stop leak treatment does ?? just increase your oil viscosity so you pay more for thinner oil + oil treatments just switch to 10w40

[@nukafan2216]

@@Techie1224 because the oil stabilizer doesn't change the viscosity too much. If anything it qould be like doing a 50/50 of 5w-20 and 10w-30. Once the lucas has been added and mixes with the oil it's not percievably any thicker. It's essentially an additive package that adds more detergents and minerals that help reduce wear and friction. This is a V-tec engine. It was designed for this oil, not 5w-30 or 10w-40. When you run a thicker oil like that it will throw off the viscosity enough so that is can trigger the Vtec indefinitely because the ECU is picking up a higher oil pressure. So you could potentially ruin the programming on your ECU, trigger multiple fault codes, trigger the oil pressure light, and even add too much viscosity that it ADDS friction and starts to wear out engine components faster, or even worse it could cause so much pressure that you start experiencing blow-by because there's too much PCV in your engine due to thicker oil. So I'll just stick to what I'm doing. I will use my $20 supertech oil and my $10 lucas oil stabilizer and $8 OEM filter. It works fine, I'm definitely burning less oil, and it runs fine.

With the engine running and the oil cap off (try both cold and hot), can you feel gasses blowing out the top of the engine?

[@B-laze_Fungist]

I got the same engine. Mine using tons of oil i think more than yours? Around 1.5L every week. I drive around 350-450KM a week. I can even see oil dripping out of exhaust when being idling for a extended period. I just found somethink on internet i was interested in trying. Basically you were supposed to take spark plugs out, and add "fuel additive/cleaner" directly into cylinders and let soak for a day or two. Keep checking on the car, crank it and add more as its working on dissolving the carbon deposits. In the end, drain oil and refill. Really thinking about this 🤔

[@paveldeveraux2729]

Still pondering the oil loss.... It is very simple, the blow-by in the cylinders by the use of thinner oil than it is designed for, simply goes trough the crankcase and out trough the combustion chamber by the way of the EGR valve by evaporation thus the high amounts of carbon build up in the pistons and provably all throughout the exhaust system ( I got the feeling that the converters are all clogged up by now )... The only way you can slow down excessive evaporation is to use at least 15W40 oil and that would reduce the oil loss at least 50%... By the way check the EGR valve and clean it out!....

[@VIDSTORAGE]

The thicker oils can damage theses newer style engines that have been being built for over 20 years because of the tight tolerance they have now and with variable valve timing ,the think oil can cause a lock up of certain moving parts.. .. I think he is having oil overeating and vaporizing problems with the oil the is using because it cannot take the heat along with some stuck rings .... ..

[@sergeynemir]

Generally at this kind of mileage, over 300 thousand miles, that means oil valve stem seals are deteriorated to the point of no return. They are generally the culprit of too much oil use and oil burning and poor performance of the engine. Engine has to suck air very good to you will have well breathing engine ! Oil in the combustion chambers means oil valve stem seals are of need of replacement.

Oil is not getting dirty proves valves are seating...valve seals may leak oil in intake and burned in power stroke creating heavy exhaust...how is exhaust does car pass emissions test ???...2. If it were stuck clogged piston rings it would cause blow by creating exhaust pressure in crankcase exiting oil dip stick and filler cap and pcv...do you agree ???...often blow by creates pressure in crankcase forcing oil out main seal as you drive and increase exhaust in pcv and throttle body...does throttle body have excessive oil varnish ???...KEEP UP THE TESTING IT IS VALUABLE TO DISCERN DIAGNOSE A FIX READING ALL SYMPTOMS...Listen watch observe...your creating an intresting video...DIY Sherlock....How is main seal ???...Have you noticed any oil trails as you pull in and park ???...You checked pcv if you block it does blowby come out oil stick filler cap that would mean it is piston rings...???...thanks for your effort most mechanics do not know how to read obviouse symptoms...they don't even try...valuable lessons...Royal Purple is known to clean engines...I have seen proof...if it is clogged piston rings adding sealants would make worse...engine oil cleaners would help but requires patience...I wonder if Royal Purple and a RP oil engine cleaner would free up dirty piston rings...Redline has a engine oil cleaner...???..

This has to be the best magic trick I've ever seen. How does that much oil get displaced in that short of a time without being noticed? Like if it's leaking while you're driving there should be evidence where it comes out and should drip on your driveway. Then if it's burning, there should be smoke. Did you eliminate the catalytic converter? It may get caught up in that yet I've never heard of it. It should still smoke when you drive it. I've known oil sending units to spew that much oil when the car is being driven but I'd think it'll drip in the driveway as well

As to the EVAP code I have a question for you, is it hard to fill the car with gas? If it is your charcoal canister has clogged the EVAP lines with charcoal pellets. This will make the gas pump click off every few seconds. If it's not doing that I'd suspect you have degraded hoses leaking gas vapors. Have a professional check it out if your not comfortable doing it your self.

Hey Dave . I have been watching your videos . and it is pretty positive to say that you are not going to get that 1.8 Toyota 1zz engine to stop using oil ,. especially at 175,000 miles . those engines are built with low tention , thin low drag piston rings . yes it could have seeping valve stem seals . But I have been working on engines for 40 years , and I have never seen rebuild in a bottle fix leaking piston rings . But I can tell something to try that will probably slow down the oil consumption quite a bit . Change the oil with Shell brand 5w30 conventional oil along with one quart of Lucas oil stabilizer . and maybe just for good measure use a Wix oil filter instead of those cheap Walmart ones . Lucas is really good to use in old engines . I have had very good luck with all Lucas products , and have been using them since I was a kid . But if you use Lucas oil stabilizer all the time , flush the engine with a half of can of Sea foam , for about 30 minutes , every ten thousand miles to help prevent any sludge build up , because Lucas does add extra viscosity to any oil. Good luck , and let me know how it goes . and if you want to try this suggestion on video that would be cool . Tim from Wisconsin .
