This is the coolant bleed bolt that sits at the end of that housing top front. After almost 10 years, I've never really had a close look at it till now. Just the usual bleed and tighten till it doesn't leak.

I'm replacing the gaskets to the housing and noticed the seal ring has had enough "a little tighter" action.

I can't find it in the PET --and neither its housing for that matter!

Anyway, it's an odd shape: it appears to fit into a recessed bowl of a fitting.

If I can't get this seal from Porsche, does anyone have a source?

 

Wrong picture from PET it is part number N 013 840 7

when its new it's not mangled like that, just a flat alum washer.

 

Thanks for the link. The PET on Pelican's link appears to be from a previous page engines M44.05-M44.10; my image is for M44.50-M44.52. Nevertheless, their PET images show the bolts and washers at that housing where mine don't, for any of the engines!

The PET I have is 9442 1988 31.01.2010 USA/CANADA

The mangle is from over-tightening (necessary each time to stop leaking , but the back side appears to be made with some kinda curved bowl shape?

Anyway, at least I have a part # to ask at Porsche. Thanks!
