2 Questions... 1 Turbo Leak, 2 PCV Replacement
 

I have a 2000 S70 Turbo, FWD with 164k miles. Top of turbo has a lot of oil leaking out. I dont think turbo works..... dont hear it, dont feel it. Where do I get a new seal for where the big, fat pipe that goes over the engine meets the turbo?

#2: Where is the PCV located and how do I replace it?

The big Fat pipe is the intercooler tube, you can get the rubber "joint" at any of the aftermarket part shops likes FCP, IPD, etc, or you dealer. I am checking right now to find a piece of silicone hose that would match.

The leak or leaks can be certain things, I know since I just traced a leak on my S70
First check (if facing your car) to the right of the intercooler tube, theres the PTC and a hose, if its super duper gunky, there might be a clogged PCV.
I did ask around for the culprits of oil leaking over and under the turbo.
Theres an oil return hard line under the turbo that leaks, this tube ends on the oil pan ( which in my case was the culprit) it can also be a leak from the oil cap rubber gasket that rolls from under the spark plug cover.

Heres a tutorial in how to do the PCV from MVF, the PCV canister is under the intake manifold to your left

Thanks for the tips and link. I will try to get a photo posted today. The turbo is all gunked up with grease. I dont even think it works.... cant feel it or hear it.
