Oil Heat Exchanger O rings on 97 Boxster

[rhardy]

Hello All,

I have been working to fix some oil leaks on my car, and am in process of changing the power steering pump.

I discovered alot of oil on the top of the engine, pooling in journals, and some little pools in the intake manifolds. I've traced the intake manifold oil back to the AOS, and have ordered a replacement for it.

In the process, I pulled the Oil Heat exchanger on the top of the engine thinking it might be leaking also.... I can't really tell if it was, but now that I've pulled it, I want to replace the O-rings.

Now the problem I am having is getting the right o-rings..... there was some kind of change to the heat exchanger... pictures usually show it with a water connection on top, mine does NOT have that connection. On the oil connections, mine has only one o-ring per oil connection. In the Bentley manual, it shows a picture of a unit with two o-rings per oil connection.... with a note that older units don't have these and should be retrofited if there is some beveled edge.

To confuse me even further, the PET parts katalog is showing an additional part "intermediate Plate" that my car also does not have, and 4 possible O-Ring parts...

Does anyone have any experience with replacing/upgrading these on a 97 boxster?

Help would be appreciated,

Rody

The oil/water exchanger with a water connection on top is not for 986 IMHO.
