Fc Na oil leak diagnosis
Hi I have a 1988 which is leaking oil around the starter, tranny bell housing and oil pan
I have tracked down several oil leaks and since then I've tried fixing my catchcan system which I believe still sprays( poor crankcase ventilation) all oil filter, oil pan gasket , oil rings in oil filter stand and the oil pressure sending unit
i thought this should fix some oil that was leaking but it's getting worse. Before it would only leak puddles during high rpm but now it leaks puddles from 1-3000 rpm. I am assuming it's the rear main oil seal or rear stationary gear oil ring but I'm not sure. So before I drop the tranny something I'm intimated by I'm going to post some pics and see if you guys can help out . Thanks for reading

Clean the area up nicely with a rag then spray it down with brake cleaner. Then start it up and wait for leaks. If you're leaking at the bell housing it's quite apparent that your rear oil seal has failed. Get someone to rev it for you so you can monitor leaks and pinpoint their location.

Rear seals arent the hardest to replace. I just did mine when I took my motor out for maintenance reasons. I used a small drill bit to start a hole, then get a screw and carefully screw it into the seal qnd pull it out. Be very careful if you do this though, its very easy to let the drill bit slip ontk the sealing surface on your rear iron. That would be CATASTROPHIC. Another place it can leak from is the oil level sender unit. Its held in by 3 bolt on the drivers side of the oil pan. Easy fix with some RTV.
