Adding up to a quart of ATF into your engine oil.

Supposedly it will clean things out.

However, it's a 5w20 instead of 5w30. Not to mention ATF has roughly 1/3 of the detergents and about half the dispersants of a quality conventional oil.

I don't recommend it personally, but what do I know.....

my grandpa used to fill the motor with 6 litres of diesel and let it idel for 5 minutes.
no oil pressure on the gauge but it seemed to clean out the crap??

[darkdan]

Great idea.....

We call that bearing and cam wear where I come from.

Considering diesel has 1/20th of the viscosity required to keep things from going to hell inside your motor I wouldn't recommend it. I'd rather have sludge and gummed up ring packs.

ok just so you dont think i am a nut this is all in good humor.
but this has been done!!!
I would never do it as todays engines are alot different than the old stuff.
but i remember a guy saying that if it burns oil you add a cup of sawdust and that will fix er up???

That's almost as good as the kid who hooked up a bag of sand blasting media to a vacuum hose to port and polish his intake and exhaust manifolds on his Audi or whatever.

The ATF trick as I understand it was supposed to be used to free up sticky or gummed up rings. By placing some in each combustion chamber thru the spark plug holes. I don't recall how much. I believe about a cap full for each cylinder. I have no idea if it works or if it does how well it would work

Piston soaks are effective at helping free stuck rings.

However, once again ATF lacks the cleaning power needed.

Things like seafoam, b-12, lube control, etc work REALLY well as piston soaks.

that is acctually not a bad idea in theroy. Extrusion honing. However I bet he screwed it up!!!

[darkdan]

No, I'm pretty sure it's a always bad idea in theory or practice.

Injecting a few pounds of sand blasting media into a running engine is never going to be a good idea. =)

LOL! That's about as stupid at the kid who had the SRT Neon who changed his oil by removing the oil filter and running the engine until no more oil came out! What kind of gene pool do these people come from?

[FB71]

same gene pool as the rest of us, just the shallow end...

Believe it or not, but I've heard that about more than just one person.

I think you'd plug your oil lines in short order, but I'm pretty sure if you read Grapes of Wrath that Steinbeck mentions that it was a common used-car-lot trick in the 20's to put sawdust in noisy rear axles, and I can see how that might help a noisy differential for a short while. There were some other interesting descriptions of shade tree mechanical tricks there too, as I recall.

But the best real hillbilly mechanical trick I ever heard was a friend's father was driving home from a long road trip in a straight-8 Pontiac (~1950). A rod bearing started to rap so he pulled into a garage and had the oil pan pulled down - a fairly easy chore. He located the offending rod and pulled the cap off, took the bearing insert out and replaced it with a length of leather he cut from his belt, and made it the remaining 800mi home!

Years ago I knew a used car saleman who would use the following recipe to fix cars that had worn out rings. He would pour a can of Ajax cleanser down the carb with the engine running. It would polish up the cylinders and seat the rings just long enough for him to unload the car on some unsuspecting buyer. I've seen it work, but I'd never do it to my own car. Mark.
