Leaky Rear Main Seal

[MikeT73]

Is this a "garage mechanic job" or should I have a pro do it?

I gotta say, it's probably a bigger job than you want. AFAIK, you have to remove the crankshaft, which requires removing the engine... this is one of those things that always seems to lead to a full rebuild and/or different engine.

Is your PCV system working properly? A clogged PCV valve can cause crankcase pressure to build up, causing oil leaks.

(found that out the hard way after plugging my PCV on purpose, )

I'm moving this post to the drivetrain forum.

I'm not sure ('cuz I haven't done it myself) but I don't think you have to remove the crank. I think the flywheel has to come off and you might have to remove the last bearing cap, but I think the seal fits over the end of the crank.

When all else fails, RTFM!
