Got the motor home finally. Drained the oil and got 3 quarts of antifreeze and then something like gear oil. Dropped the pan and looks like there is mud in the pan. And the motor is locked up.
The block, head and VC are all yellow. But the pan is blue. Did they paint 198's yellow?
Either way, going to yank the head and knock the pistons out of it soon. I expect the block is junk, but even if it isn't can't see a way to ship it to anyone and doubt someone local would want it. And the only thing special about it is the 198 stamping, if it is even there (I didn't know to look and haven't checked yet).
