I just installed a new clutch/flywheel. I replaced the rear main seal which was leaking badly and I replaced the rear cover gasket. But I'm still getting an oil leak that is only on the passenger side and back of the motor. It is mainly around the starter and is below the crank position sensor. The OPSU looked good when I replaced the clutch and there seems to be no oil coming from above the crank position sensor. I used sealant at the bottom of the rear cover but maybe I didn't use enough? Any ideas as to where this leak is coming from?

PVC hose?

Are you thinking it's a clogged hose or a bad valve?

Can you see back behind the flywheel to see if it's coming from the rear seal?

I think a rear main seal leak would be visible on the flywheel. The flywheel seems to be clean to me. I hope it isn't that because I just replaced it.

I like the thought of the PCV valve/hose though. I'll get that replaced, make sure the hose is reasonably clean and see if that helps me.

Give it a good cleaning with some brake cleaner/oil dissolver, then start over by inspecting after each ride.

Time for oil dye and black light

Maybe no relevant but clean up under there and double check it's not cracks in your oil pan, that's what I'm dealing with right now

I have the same exact problem! Did you ever find out the cause? Please let me know!

I had a crack in the oil pan around one of the bolts above the oil filter that was giving me leaks and then another leak was that the dipstick was not seated all the way in. When I would go WOT is when it would leak..... just a thought.
