Cap Fell Off block... Leaks Oil Can You Identify It?


Recommended Posts

I lost some sort of cap today and its leaking oil. I am not sure what its on, but here is a picture. I am hoping someone can tell me what it is so i can order a replacement. Any help is greatly appreciated. :thumbup:

Its located up on the right rear facing the rear bumper/ cats etc.

Excellent Thanks Ahsai! Is this just a screw in lid and is there a compound that accompanies it?
Actually I think it's this brown one instead. http://www.autoatlanta.com/Porsche-Cyl-Head-Covr-Sleeve-Parts-PN-T99610421602.html

It's much bigger than the green ones (#26 in my previous post). It just snaps on and no sealant is needed.

You can measure the size of the hole to make sure the part is right.

Thanks again Ahsai!. What would have been the harm of it being driven after these happened? :cursing:

It should create a major oil leak, with everything that entails. A larger question would be why it happened in the first place, these plugs simply do not fall out on their own..............

That sir is the real question. I do not know what would be the cause. I was at the track autocrossing, did a 360 and did not hit anything. Thats when this all happened.

The oil pressure and levels dropped but not to significant levels. There were no alarms or CEL indications.

It was drove off the track and retired for the day :(

They are metal are they not? So I really don't know how or why it came out.

No, they are synthetic rubber or plastic material (flexible) and held in by friction and the sump vacuum:

Picked up the part today.

Ahsai it was the second one the brown one. the greens go on the other side of the camshaft head (towards the front of the car) brown goes in the rear.

FYI,

they are metal coated with something.

These can pop out if oil pressure is too high against the plug -- I've only seen this when the valve cover had too much sealant used when replacing.

This gummed up some of the oil galleys and forced more oil against the seals.

None of that work has been done to the car. So how it happened I still do not know.
