Thanks for the help Rcpilet. Rebuilding an engine can cost more than just buying a new one sometimes...

But if you can get several more years out of it, what the heck...
I remember someone saying that After-Run-Oil is a 50/50 mix of Air-Tool Oil and ATF, is this true? If so, does it matter what brand air-tool oil and or what grade ATF? I have some Campbell Hausfeld Air-tool oil and Super Tech Dexron-III Mercon ATF. Is this ok?
