Porsche Crest oil liking in the 3.0 engine

Hi all,
I brought my 911sc to a garage and they told me that I have to find some seals to repair the car. the seals are old and the oil is liking to the cars ventilation, so I cannot use the heater. Do you know which seals are? Because they r French and I do not understand a word.

Cheers
Alvaro

possibly the valve cover gaskets?

best bet is to get under there and look for yourself, maybe snap some pictures.

My guess would be leaking oil return tube seals. They are right over the heat exhangers and you would probably get an oil smoke smell when the heater is on.

Here are the oil return tubes.

Can you send the mechanics the link and ask them if these are the seals (and tubes)?

Do you have e-mail access with them? Some folks here speak French and could type a brief note for you and interpret their response.

Yes, I do have the email. In the cars diagnostic, they do not speak about specific seals or gaskets. But I do not know how to ask for the name of the seals to order them. I can use the google translator but it is not the same...
Thanks guys.

The car originally came with non collapsible.
In order to replace the seals while the motor is in the car, the collapsible would need be used.
Yes four tubes and 8 seals.

Mawa, I live in France and speak Spanish and French. I sent you my phone number by PM, so feel free to call to let me know if I can help dealing with your French mechanic.

(Sorry for this first post without a proper introduction, will get to it asap.)

Hello Alvaro !

I also live in Spain (El Puerto de Santa Maria, Cadiz). Welcome to the Porsche world !

those oil leaks can be located in very different places. That oil might come from the top of the engine (thermostat seal, oil pressure switch seal, oil breather cover seal). There are also common oil leaks in the oil cooler seals, or in the oil return tubes seals, or even form the cilynder/engine case seal due to broken cylinder head studs. You can also have leaks in the valve cover seals.

Have your car inspected before starting buying parts. You can also do it but you need to have your car with you. Use the forum search tool and you will find really good info.

Donīt hesitate to ask as many questions in the forum as you need. Nice and helpfull guys.

Regards

Miguel

Mawa, I spoke with the shop in Tours this morning. They did not identify where the oil was leaking from. However, they did see that your heat exchangers were sending burnt oil fumes to your cabin.

Looks like it's time to perhaps drop the engine and fix oil leaks, and then go for new or good-condition-used heat exchangers.

Good luck with everything. You have my phone number, feel free to call anytime.

Ben.
