I realize this is an old thread, but to keep things organized makes sense to post here.
I have 06 EXL and all of a sudden, my rear main has apparently started leaking quite a bit. It drips on the undercarriage and gets on the hot exhaust and smokes. I have gotten under it and am sort of semi-pro mechanic so yes I know what I am looking for and engine was clean prior.
Looking for info, did this seal replacement solve issue? One would assume it would have, but I read on the technical forum (non gen specific) of guys having to have dealer replace this more than once for this problem, which would seem to point to something else. I am also going to test the PCV valve to make sure it works properly.
FYI - I purchased van with 55k and swapped in Mobil 1 5-20w and have used that. Van started leaking about 97k. I have purchased other used vehicles and swapped to Mobil 1 and never had a oil leak problem.
Melton46 - Looks like you do great work and have the equipment. Looks like you have to use an engine hoist to support the engine when you remove the cradle and tranny?
