I have the exhaust off for a center muffler delete install, and notice some drips hanging under the engine at the very rear.
Nothing is on the floor, so not a major leak, but I can see that it must have leaked a little for a while based, on the smudge build up in the area.
Car has been stationary for 6months now.
I was thinking FMS (crank pulley), but I see no wet areas behind the pulley, only dried up smudge. The wet areas are on the cross over tube from cylinder bank 1 to 2. What area the common areas causing such a leak? I read someone else had changed some aluminium seal/crush rings in the area, but I am not sure where they are located?
Wet area seen in picture. The cross over tube was wiped a litte, drips where hanging in the middel of the tube.
The PS pump is on the right side of the motor if you're looking into the bay. That seepage seems on the other side. Most common place you'll see seepage is at the connection of the pipes to the tank. And I don't think you'd see dripping where you are seeing it.
You really need to clean it up and even just idle it, run it and see if you can identify the source. FMS is one possibility. There are other bits in that area.
I'm thinking check power steering. It leaks a little from the top of the reservoir tank and forms that sludge mentioned.
Now.....don't buy a new tank. For hundreds of dollars. Like Porsche mechanics for road car will propose. The Porsche Motorsport department sells a repair kit they used on the 997.1 cup for about $20.
Tracing from underneath it seems the origin is the center of the engine between the very lower part og the case and the pulley somewhere.. Pulley area not wet.
I'd bet it's front main even though you don't really see it around the pulley. Mine made a mess all below the pulley and I'd get oil basically migrating down the center of the cases where they came together.
Good news is if you're handy with tools and know what you're doing in there it's not that bad of a job. Set aside an afternoon and grab your favorite 6 pack and have at it.
I'm not sure the engine carrier can be removed in place. In fact, I think it may cause coolant to run out when you pull those bolts. Which maybe you can get at with the bumper removed... Man, trying to remember someone here tried this and it made a mess... I think it was that.
