AOS Seal Problem?
I have a 87 944S with 78000 miles on it. It runs pretty good except I
am getting some oil smoke at high rpm at full power. Other then wot
there is no smoke at all. The oil and coolant aren't mixing, I checked
the leak down and it's all under 10%. I see that the AOS seals can
go bad and allow oil into the throttle body...
A note, the car also seems to have a small vacuum leak I can't seem to find,
idle speed is between 1050 and 1100.
Could all this be related to the AOS seals? Is there any way to tell other then
a leak (my car has no leaks) if they are failing?
