[QUOTE="wfooshee, post: 823465, member: 6354"] I'm not sure how good an idea the "DO NOT LET GO" is, as mongo current goes through the starter windings, and it's really really hard to get to it when it needs replacing. I understand the reasoning, though. Loss of compression sounds like a reasonable hypothesis as to the cause, with the symptom being faster cranking, but rings aren't the only place compression could be lost. Valves not seating seems a possibility, but how that would fix itself after sputtering for a while is beyond my simple understanding. Loose in its guide so it doesn't seat, sounds really bad. Sticking open, sounds really bad, too, and [I]really[/I] bad if it's sticking far enough out to meet a piston. Rings, on the other hand, would recover with some oil pressure, but it shouldn't take that long, I wouldn't think (again considering my limited understanding of what actually makes these things work.)
