It's been a while since I did a 964 motor.
I have the case apart and looking at the o ring situation and through bolts etc. When I removed the through bolts, there was only 1 O-Ring fitted to each side.
Also, the engine number I have does not fall into the category of the TSB that says they need modified washers and double o-rings.
So I measured the depth of the recess in the case with the end of my vernier.. and it came to approx 6.25mm.
When I compare the vernier to the through bolt with washer and o ring, it seems that the o ring will NOT be in compression at all.
If that is the case, then how does the through bolt seal?
Has anyone else measured the depth of the recess in their 3.6 case?
