Help with oil leak
89 Carrera 3.2
It never leaked a drop. Replaced the clutch and main seal and it started leaking. Replaced the main seal again with a genuine Porsche seal. Its still leaking. Looks like its leaking down the side of the cooler where it meets the engine. What might be the cause? When I had the engine out. I did not notice excess oil in the triangle of death area. Many Thanks, Chris 89 Carrera 3.2 Last edited by cmcfaul; 02-27-2022 at 12:45 PM.. |

Usual suspects: Triangle of death, failed cooler seal, failed cooler.

Remove the air flow meter assembly so you can see the TOD area.

I think its coming from the upper cooler seals. Maybe it just needs a tightening (doubt it). Taking it to the shop today to get a professionals opinion. I thought it was the main seal as I had replaced it when replacing the clutch and the leak started so replaced it again, huge pain in the ass. I am getting burned out on fixing it. Pretty sure its not the main seal.

I was able to remove the oil cooler without dropping the engine.
Per Ivan, be aware of this tech bulletin if you end up removing the oil cooler. https://forums.pelicanparts.com/porsche-911-technical-forum/1011282-leak-cooler-seals.html#post10227300 Last edited by thetorch; 02-28-2022 at 09:01 AM.. Reason: typo |

The top of the engine is wet. Believe its the oil sender. Gonna replace that and hope for the best.
Thanks, Chris |

Do some JB weld around the plastic at the crimp with the new one, they leak there after awhile.

Even the JB weld reinforcement isn't forever.
I fabricated a plug for the idiot light sender when my reinforced one started leaking, and bought a VDO two pole sender unit I have mounted at the rear (of the car) of the engine where the oil pressure sender goes. This unit combines a pressure sensor for the gauge, and an on/off switch for the idiot light. Hasn't leaked yet, plus if it does it is easy to get at. Just calls for a short wire extension for the idiot part. |
