FatCatDoS Posted August 28, 2016 Share Posted August 28, 2016 Hey guys. I have my oil pump off the car and disassembled. I plan on replacing the o rings, seal and Mickey Mouse gasket but I thought I'd check the rotors. The inner rotor looks to be scored where it fits in the housing. I can feel it with my thumb. Should I replace? And if so where can I find it? I can't locate the part #s. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted August 28, 2016 Share Posted August 28, 2016 techincally speaking i think you measure clearancs and follow the FSM as there are three different variations of rotors (A, B, and C maybe - does yours have a stamped letter on the face?). get the FSM and see the spec's it calls for? what's the history - why are you disassembling it?

FatCatDoS Posted August 28, 2016 Author Share Posted August 28, 2016 I do have an FSM. And I have B spec'ed rotors. I see the specs it calls for but I mean the actually rotor is is scored. It feels thinner where it goes into the oil pump housing. I'm rebuilding it because it sat forever and I haven't started it myself. Motor has over 200k and I'm resealing and making it right. Someone has already been in this pump. It didn't have the oring behind the rotors. Quote Link to comment Share on other sites More sharing options...
