I'm in the middle of replacing the front seals and belts, and don't know if it's the Cam seals or Crank seal/oil pump sleeve that are leaking.

What do you guys think?

Here's the crank seal:

Here's the waterpump, looking up at it from the bottom:

Here's the Cam gear, but the oil residue/stains are hard to discern from the picture b/c of the camera's flash:

There was oil dripping from the bottom of the belt covers and I thought it was the crank seal/oil pump sleeve all along. Now I'm thinking it was oil leaking from the crank gear, past the waterpump, and down to the bottom of the belt covers?

Can someone please look up all the front cam seals and the cam sleeve part numbers? I appreciate it.

================Update==============
Went to the car again last night and noticed a small amount of oil pooled on top of the lower balance shaft housing. That area is surrounded by the bottom side of the water pump and edge of the oil pump. Would either one of these leak oil onto the top of the lower bal. shaft housing?

The water pump was recently replaced, so could it be that one of the bolts is not torqued properly and allowing oil to leak? What's the torque spec for the water and oil pump bolts?

I still think the oil is coming from the cam seal (will find out soon), but it seems all of the oil and stains are by the waterpump and b.s. housing.

Any thoughts on this? Thanks...

 

Porsche offers a front seal kit with all the seals, mylar seals(behind the sleeves, clear plastic),sleeves. It does not have the crank seal, sleeve, or O-rng. The larger seal goes in the lower balance shaft. The rest is the same. think it comes with the large O=rings for the cam and balance housings too.

 

please see the edit to the post up top. thanks.

 

Oil pump to crankcase: M6 is 8 NM (6 ft/lbs), M10 is 45 Nm (33 ft/lbs)...I believe the water pump is M6 as well so they have the same torgue values...

Here are a couple of PET pics with part numbers...

Probably a good idea to change the oil pump seal, o-ring and sleeve while you are there...

Let me know if you need any other pics, etc...

 

Knda sounds like the O-ring at the back of the distributor housng. All three of my engines had the same oil coming from there. It ran down between the cam housing and the dist. housing, down the head, over the edge of the w/p and down on top of the lower bal. housing.
