I just thought I'd chime in on your question of the bad compression. I just read on another thread saying that his compression was terrible when it started up but after it warmed up it was up to par. So your engine could be fine when warm but when its not you could have horrible compression.
just done sue me if im wrong. :lol: Im still learning.
Luckily it was just bad wiring, and biodiesel melted fuel lines.
I'm curious about the bad compression on start up, but normal when it is worn. Would that be a bad oil pump, or could it be valves out of adjustment?
