Hello All:
Question on deck height.
Background Information:
1969 911T Stock 2.0L motor
Re-assembling top end with one new piston. New rings and reconditioned cylinders. Piston number 3 had both skirt "tangs" broken off and recovered intact.
Cases never split. All original components 67k miles.
To my question: When I measure the deck height in accordance with the pictures shown I get a value or 0.40mm with the 0.25mm copper gasket and predictably 0.65 with the 0.50mm gasket.
Basically, I'm re-assembling just as it was prior so the ~1mm deck height suggestion is not making sense to me.
The 2.0 T engine has the head gasket that is "flat" between the head and the cylinder. I.e., it doesn't fit in a groove. Additionally the used (compressed) gasket is approximately 0.65mm.
I'm trying to pick the "best" thickness of copper cylinder to case gasket. and I'm thinking it is the original 0.25mm thickness - correct?
Note: Although I want the right number I don't think it's critical within the range in question. The piston will fit several millimeters "up into the head without interference."
Thanks, Bill
