What is this stuff?

Found it in the bottom of an engine in "unknown" condition...

It's everywhere in the oil, and there is a 3/4" build up in the bottom of the pan. I scraped it out, it was kinda "hardened" in the pan. But with my fingers I could loosen it into a solution again. There are "lumps" of it that can also be smeared into a fine granular solution as well.

I think it is some kind of engine additive. But what? All the bearings look good, the cam and lifters look good, there is no scarring in the cylinder walls, but no cross-hatching either.....

No real clue from me Aaron, but 99% of the "core" engines I get back look like that in the bottom when I do teardowns. I'm guessing it's lack of oil changes, engine metal, and bake at 230 for 6000miles plus. /ubbthreads/images/graemlins/crazy.gif

I'd say DD called "Bingo", but then again I don't rip apart junk that someone else abused (just the junk that I abuse).

Go wash your hands please. /ubbthreads/images/graemlins/laugh.gif

I once saw a late 60s Plymouth Valiant with a slant 6 that was so full of that sludge it had started to cake up to the point that you could roll it into a ball and toss it around the shop. It turned out that the guy who owned the car never changed the oil, he just added a little when it got low.
