Sent my car in for a oil change and to change the valve cover gaskets. We found oil collected on top of the engine under the air intake. On removing the air intake pipes (mine is a 1995 so no varioram) we found oil inside the intake manifold???? How can oil get there?? I do have a cut out airbox with a K&N filter could oil be sucked in through there??

I am seriously concerned can anyone advice me if they have faced this problem before or with any information on where the leak could come from...

Thanks in advance guys

I noticed this when I first bought my car and had the intake manifolds off for my wiring harness change. I think there might've been around a tablespoon or two present?

I'm guessing it gets there through the breather vent plumbing.

I had the manifold off again for an oil pressure sender change and didn't notice nearly as much present which leads me to believe the previous owner was running the oil level a bit high.

Make sure you don't overfill your engine with oil. I normally run about at the halfway mark on the dipstick which coincides with about a 4:00 position on my oil level gauge.

Hi Deltajetfixer

Thanks so much for your advice. We dont have an official Porsche centre here and issues like this leave me stumped. I am really glad that we have this board.

The car was overfilled the last oil change so I suppose this was the cause. However there is quite alot of oil in the manifold pipes. Is this a problem??

Thanks again

Sounds like the engine has been over filled with oil.

Thanks a lot guys. Looks like the problem will be solved. My Car is in for an oil change and they are also replacing the gaskets on the valve covers. By the way I did receive the gaskets from FVD but my mechanic tells me that there is a cork sheet and gasket also???? What are the gaskets supposed to be made off??

On a 993 which I'm assuming you have since you said '95, the valve cover gaskets are rubber.

You should have 8 separate pieces: 2 large (one each for each lower) and 6 smaller gaskets (3 each for each upper). They are pretty substantial looking and definitely not cork sheet.

Yes the gaskets are rubber but they have a thin cork sheet on top of them. Has anyone seen this. My car is a 1995 993.

Thanks
