Oil pump leak

[umn]

Hi,

just noticed that my car is leaking oil from the rear of the engine, where the oil pump sits. It seems to be coming from the split line between pump housing and crank case.

Are there any TSBs on this or has anybody come across this before?

Cheers,

Uwe

This the only one I see for oil leaks at the rear of the engine.

TSB 11/99 1001 Oil Leaks/Engine Bolts (dated 2-9-2000)

Vehicle Type: 911 Carrera (996), 911 Carrera 4 (996)

Model Year: As of 1999 (X)

Concern: Oil leaks/new engine bolts

Information: As of July 30, 1999 production and engine number

M9601 66Y 00871,

micro-encapsulated fastening bolts are used on the engine in the following areas, to prevent oil leaks:

1. Flange for intermediate shaft (qty. 3), M6 x 20 (Figure 1),

2. Oil extraction pumps (qty. 8), M6 x 20 (Figure 2),

3. Engine crankcase bolts (qty. 25), M6 x 35 (Figure 3).

When performing engine repairs, new micro-encapsulated fastening bolts should always be used.

Parts Information:

Thanks for your help, Loren. It looks like the problem is the O-ring that seals the oil pump against the crank case.
