The car itself was very very clean, a california car, and it showed 50 some thousand but who knows it was a 99k odo on the 115 body and it could have been turned over many times.

When I got it it had a holed piston iirc, with one cylinder that was down. A local indie who enjoys a good reputation but whom I have always fealt leery of had replaced the ip but of course that had not solved the rough running.

Makes you wonder if the PO ever changed the oil.

Since I retired Iv'e bought several 240Ds with blown engines and in tearing them down, I gota say they all looked good inside, no "sludge" under the the valve cover or in the pan like you'd see in a gasser. I guess Ive never seen a warn out one:P

I figured either it had a million miles, they never changed the oil (like 240joe) or possibly never replentished the oil bath air filter and ran it unfiltered for an extended period.

When I got the car it had a big auxiliary tank in the trunk, so maybe it was used by a traveling salesman who did bags and bags of miles.

I just helped a friend rebuild his three cylinder, Isuzu excavator, engine that had been run with a broken air cleaner bracket. We could actually wiggle the middle piston in the cylinder. This damage occurred in only a few hours of running in dusty conditions and the engine really didn't have that many hours on it. Really illustrated the need for clean air in an engine.
