Well, I almost posted a question as to if that could be an issue, then deleted it. The cover for the flywheel was missing, and there was at least a wasp nest up on top, if not more. Rats were all through this truck. There is an inline 6 on a retired well driller rig over yonder, I think it may be a mid 60's. I am going to check on the cover and the dipstick to see if they match.
