Gary/Kelly,
Your figures seem more accurate given mine are too big.
The Oil rings are the same size I have now recorded.
The Inner coolant ring of 8.932 ID is indeed smaller than the 9.111 ID.
The Outer 11.182 is also smaller than my recorded 11.230 ID ( which is down
from Paul's original figure of 11.340") - I figure that yours must be right.
Gary, are your "O" rings red in the middle with a clear outer covering!?
It's just that it looks different to what I've seen in photo's.
Do Creavy take back and exchange?

Hi Kelly;
I believe Paul's numbers worked out to be:
Oil O-rings
0.093 x 4.68
0.118 x 4.33
coolant O-rings
0.093 x 8.932 (0.098 not available)
0.093 x 11.182
I ordered the coolant orings with 9.00 and 11.25 ID, they fit without
stretching and had a bit of slack, I would get slightly smaller next
time.
I should also add these were for an '86 NA. I assume they are all
supposed
to be the same but I have seen some casting differences between
housings.
The 0.093 x 8.932 were originally listed as .098 but I was told by
Creavey
this size is not available.
These appear to be narrow in the wide groove but have an approximately
correct "nominal squeeze".
Biggest problem seems to be getting the oring to stay in the groove
with minimal hylomar during installation.
I believe the ones you want are the SIL/PFA o-rings good to 500F.
Ask for them specifically.
Haven't run the engine yet to give any real feedback.
Cheers
Cary
