has anyone ever heard of using transmission fluid as engine oil to free stuck piston rings. I heard this from a couple of guys i know but it doesn't sound to good can anyone help me

free stuck piston rings????

punkindrublic

you can use engine oil as tranny fluid but i'm not sure if its reverable....

how do you know they are stuck though?? if they are in the motor they shouldn't really move from there place when installed... so they couldn't really get "stuck"

ya, i've heard of it, just don't leave it in too long cuz it'll soften up your seals..
leave it in for a day or two then get it outta there with an oil change..

punkindrublic

what causes this to happen though??

dingus8

lot's of carbon....I've never saw it or heard of usign tranny fluid....I just know of it from buildign 2 strokes and racing them cause it is a more common thing for them seeing how they have oil put threw the combustion process in order to lube rings piston and crank.....

red90dx

if the motor has not been run in awile like motors from jap auto,
put some oil down the cyl and pray they open up...this will not help a siezed motor but rater a stuck ring

the rings get stuck by something called cylinder "wash"

its the gas in the cyl that cause the rings to compress into the piston causing low compression/no compression in the cyl.

The tranny oil works like a charm you have to use automatic oil though, It is high in derergents, and decarbonizers, leave it overnight and it will free up lots of carboned up ****. Last time I rebuilt an automatic, all I remember is having clean hands after.

ive done this on a rotary motor,
rotors were stuck, the car didnt ran for years then when it was fired up, cloud of smoke came out the back.
and yes, use ATF.

i did this to my oil burner used tranny fluid for an automatic tranny with dexron III and it stoped alot of the oil burning now only a little tiny puff barely see it it losens up carbon and frees up stuck rings , cleanes your inside of the engine lke valves and stuff in engines that have been sitting for a while i definetly reccomend that you try 1 litre of tranny fluid for auto tranny quaker state is the best i find with dexron III try it for 300 Km or so if you can do it in a week then flush everything out buy a jug of motomaster supreme 10 w 30($7.50) run u r engine till its hot (fan comes on) leave the old oil filter on for this then do a regular oil change wiht some sort of synthetic oil and your good for another 5000 Km

so how much to pull the ATF in ?? i've heard that dropping a few drops into the plug hole and put back the plug, wait for a nite, then do the oil change, and it's fine. isnt' it like that??

1/2 litre

Marty, he's asking about the piston soak...

you are talking about the crank case... two totally diff't things.

1/2 liter of oil in the plug holes will result in hydrolock!!!

h22a, use 1 oz overnight in each cylinder or like Marty said, use 1/2 liter added to your normal engine oil - don't overfill your oilpan.

oops..ah well, whaddaya do..

ya, 1/2 litre to your engine and run it like you would normally for a day..

imported_loudsubz

can you just put in all ATF in your engine instead of 1/2 litre?

Like drain it all out, put in the 3.8l or so of Oil the SOHC use then a day later take it all out?

Matt, I'd get quite concerned about that... we don't even know what weight ATF is? I would not try that! IMO, Marvel Mystery Oil 1 liter + 2.7 liters of regular 5W30 and run for 200-300 kms, then drain and refill. Or use Amsoil engine flush

Matt..shyt no
tranny oil is a lot lighter and has completely different properties..
all yer after is to borrow it's detergent properties for a bit to free things up, rinse down the shyt from inside the engine..
that 1/2L is no more than a day either imo..
