Have any of you found a bad oil pump main seal at your 60 K? I would assume the seal be removed from the oil pump. I can see a few drops of oil coming through the bottom of the cover.

Thanks,

if you can afford it, go ahead and replace that oil pump too.

Thanks for the advice Matt. The oil pressure looks OK, so I think I'll leave the pump. Do you know the front crank diameter? I'm going to need a seal/bearing driver or a large socket drive the seal. I haven't pulled the crank pulley yet. And I'd hate to buy another Mitsu tool.

Thanks,

yes there is a gasket on the oil pump. but i think his problem is that the little round seal that fits over the crankshaft is bad.

My oil pump went at 85k adn I spun a rod bearing. Just food for thought.

matt - yep it is the seal around the crank, housed in the oil pump. I have to pull the crank t-belt pulley and crank sensor to get at it. The pulley is keyed, I don't know if I need use a puller on it. The leak isn't bad, but it is only bound to get worse. Any idea what the inside and outside diameterof the seal is?

Wow - your pump went at 85K mi. What were the symptoms - low oil pressure and knock? My pressure still looks OK from the threads I've read on the subject.

yeah, 85k. My symptom was low oil pressure and the result was a spun rod bearing, enlongated rod, and marred crankshaft. Unless you are so poor that you are eating bread crums for dinner I would really recommend changing th entire pump. You are gonna have it off anyway!!! That will save you the trouble of find the correct bearing.

Oh, go to autozone and rent their 5" puller. It will save you a lot of time and headache. They give you your money back when you retur it, so it is free.

I spent 3 days trying to get the f-ing thing off. I had all kinds of jerry-rigged contraptions that didn't work. So I finally gave in and went to Autozone to get the puller. No joke, it came off in 2 minutes with the puller!!!!
