@hahnmgh63, it has 155k on the car so it's probably due anyways for a turbo rebuild.

Update:
I have the car and engine pretty much stripped as far down as I was planning on. The valve cover gaskets had a little bit of weeping but once they were off it looks like the left side cam chain tensioner is shot. The guides are worn out for sure. The right side tensioner guides look good and the chain is tight and when I push down on the tensioner it gives a little then pops back up. With the left side the chain is loose and there's no give/return of the tensioner which makes me pretty sure that it needs to be replaced. Does that sound right?

The other area of concern is the rear main seal. There's a *little* bit of oil weeping through the seal, you can kind of see the light reflecting off of it. The bigger worry is where the rest of the oil on the back of the block is coming from. Could this just be oil from other parts of the engine migrating up from below?
