I use ATF on the piston rings when installing new rings... I have read a article were a high performance builder break's in his engines with ATF then drain and add motor oil... I don't believe straight ATF is a cure all oil for stuck rings tho I may try it but it would be real low on my list of better known carbon buster... [Reply]  [No Email]

Aluminum valve bodies would erode pretty quickly if the fluid was abrasive. There are friction modifiers but those are chemicals, not abrasives. Old used ATF is probably a bit abrasive from the crud it's picked up along the way. [Reply]  [No Email]

Just remember all ATF has an abrasive additive in it, type f is the worst. Do you really want that inside your cylinders. buy a gallon of a good penetrating oil and use the right stuff.

It's a great way to loosen up rusty parts. I put it in a pump type container and have had no issues at all. I recently had problems with my 9N not starting, and through Dell, on this site, found out my rings were stuck and had no compression. I followed his instructions using plain ATF, not synthetic, and it worked perfectly. I suggest starting your tractor outside though when you're done. The ATF burn out filled my garage with smoke. But actually I didn't care, I was so happy to hear it run. Which ATF? The cheapest! [Reply]  [No Email]

Better use kerosene or diesel with the ATF. The acetone will rapidly evaporate out and spread highly volitile fumes in your shop leaving just the ATF. [Reply]  [No Email]

It's better to use as an un-sticker right while you are working on something. atf / acetone is what I finally used to unstick my valves as I used a deadblow and copper hammer to drive them outta my head on my 4 cyl 4000. stuff don't stay mixed long either.. I'd swirl it around in the squirt bottle to make a pink mix and after 5 minutes it'd settle out. fortunately I was working in the barn.. and open air and not the shop. i hate the smell of acetone or ammonia...

Years ago at the boat plant we kept a 2000 gallon tank of it. In the early 80's I started looking at the new MSDS's on all products used in fiberglass boat production. Many bad ones were gone quickly, acetone had no substitute till the late 1980's then it too was very quick to go! Just look at the MSDS for it, should be enough to convince anyone. In the marine business diesel and ATF was the most prevalent rust buster and as you know salt water and air provide plenty of rust. We tried anything and found Diesel/ATF was the best. Pity the fellow that mixes acetone/ATF in a pressure sprayer, that one is an explosion overdue. And yes ATF does have abrasives and some seal damaging additives too. Better safe than sorry.

They can modify in either direction depending on what the application calls for, and if something that will increase friction is required the stuff is still microscopic and isn't going to clog valves. That said, frcition modifiers in ATF have traditionally been friction reducers. The first ATFs actually used whale oil! There's been a lot of trouble in the MC world lately, when people put friction modifier ATF in primary cases and find their (wet) clutches stop working. I doubt any of this matters in our application. [Reply]  [No Email]
