I noticed a couple of drops of oil under my 2007 Turbo, 18k miles. Under the left rear. It's spread out a bit and only leaks after driven and warm. I've attached a picture and wondered if anyone had a suggestion. I may just try and clean the area and see where leak starts.

I think that you have two or three leaks

The area circled in RED is a crush washer the fails and is a common failure point on 996TT/GT3/997TT

The other Yellow areas are the seal between the Brake booster pump and the cam housing scavenge pump cover

Thanks, I guess it's off to the dealership I go.

i have the same leak ( red circle). Is this DIY fixable or difficult?

Thanks in advance!

I haven't had to tear into this area before, but looking at the PET it looks like the sealing ring that Kevin was talking about is # 7 on the diagram. Less than $2 from your friendly Porsche dealer..

Might make sense to replace #6 as well? It's hard for me to know exactly without looking at it in person. Its about $26, so maybe look at it first to see if it needs to be R&Red?

Also, dont completely discount the possibility that the leak could be coming from the tandem pump O-rings as well..

I'm betting number 7 or number 9 on Saabin's parts list.

A nice afternoon job>>it takes more time to clean all the oil smudge.

Do a oil change a lube your VNT linkages...

Turned out to be a loose bolt/plug, see pic. The star head. Could heat from DE event loosen this up? Awesome Euro car shop in my area (NW IN) found and tightened it without raking me over the coals.

Torque specs should keep fasteners in place across the heat values an engine would see. Did you have any work done in that area previously?

Nothing aside from an oil change this past Spring.

Mine leaked there too. That bolt keeps one of the small chain guides in place. I think they have a small seal on the other side, can’t quite remember. I replaced mine when I pulled the engine. No leak anymore. I did try tightening it first before I replaced everything and unfortunately it did not do the trick for me.
