Both the pressure plate and pressure ring seemed to measure level and fine across multiple areas. Nice and flat all the way around. When you say "measure the oil pump cover" what exactly do you mean? Measure what? I can definitely feel the worn areas with my fingernail so I might just replace the cover. As long as just replacing it is fine... is there some measurement with the oil pump itself that I have to do? After looking at the teeth of the flywheel, I came to that conclusion as well... it has to be from the starter teeth. They look fine as far as I can tell, but I should probably remove the starter and clean/re-grease it. Is there any way to remove the starter without having to remove the front cover area? I've already got the crank blocked and I suppose I'd have to wait until the new transmission is back in before I unblock the crank and remove the starter.
