Yes, but it's not the oil pan most of the time. The rear main seal actually leaks pretty often on these cars. I know the oil pan does as well. But I posted the picture to show what a leaking rear main seal can look like. That may not be what's leaking in that picture, but that's what it looks like when one does leak.

No need lift:

This is an engine support bar from Harbor Freight, $60.

No need to completely remove subframe either, just need to lower it enough to remove/install the oil pan:

yeah, thats what I said, lower it. Hmmm, didn't realize the engine support was that cheap. I got my engine stand from there, might end up getting that support. I'll do my oil pan and rear main at work on the lift, but I think I'll buy the support just to have it.

Coming back to rear main seal - if you don't have transmission off yet you can't say for sure it is leaking. I'd recommend to replace the oil pan gasket and test it first.

I've done enough of them, I know they leak. Mine very well could be the oil pan. I'll inspect it more when I eventually take the oil pan off. But mine barely leaks so I'm not all that worried about it right now

Thank you for a good write up.

If you can add Transmission shifter selector shaft seal for manual trans would be great.

It's good to know that if you have any one of these leaks, you definitely know it. I keep my engine bay very clean, so I believe I'd notice any of these fairly quickly. The leaks look like they will leave a lot of residue should it happen.

Awesome thread, I think two of the pics in the OP's original post are from threads of my leaky E46 lol! My car has come a long way from those days, it's threads like this that really help newbies to solve problems on their own. Nice Work!!
