Default Rear crank seal

I've heard of a failing front crank seal, but what about the rear? I've always had a small oil leak that I couldn't pinpoint and now I pulled my tranny for my AWD swap (YAY!) I think I've found it to be the rear crank seal.

Info?

Thanks!

I have the same leak. It is a slow leak. I would have changed it but did not foresee it and did not order a new one. So, mine is still leaking slowly.

I imagine it is pretty common. The oil tends to gob up with the clutch disk dust and thicken enough to not drip for a while. So it is'nt really found for quite some time. There is an inspection cover that can be removed for finding this leak. Though I believe it may require lifting the engine a tad to gain access to the bolts.

Good luck with your awd swap.

Thanks for the info. Tomorrow when I take the flywheel off, I'll better inspect the seal and probably order it then.

Also, the oil seperator plate on older engines is plastic and tends to leak. Get the replacement aluminum one for ~$30.

I think 2001 it was changed, maybe 2000? Prior to that it was plastic.
