993 tt and oil

Recommended Posts

Hi everyone, I'm writing here cause I have a question/issue onmy 993 tt with oil "mess".

Since I had some oil loss from the upper valve covers and from one chain tensioner cover, I decided to remove the engine to do a proper job.

But when I had it out I noticed that the complete intake was full of oil, a lot in front of the turbochargers and in the Y pipe.

I had to remove the turbo ventilation hoses too and the right one was practically full of oil... I have to say that the turbochargers are both just revided.

 

So I decided to remove the complete intake RAM and looked in the intake valve channel. I attach a picture but i was surprised the valve steams looked incredibly clean, and "yellow".

The exhaust valve (seen through the intake) looks white as from oil combustion.

So, for sure I'm burning oil, nevertheless the engine is not smoking at all in any condition (cold start, running, accelerating or coasting).

 

I have no experience with Porsche engines but this yellow color of the intake seems "funny" to me, never seen this before, same for the clean valve.

Is this normal or a problem? Has anyone ever seen something like that?

Thank you very much for your help

 

Regards from Switzerland
