I have a 73 911T. It does NOT have the original engine in it. I have had a few oil leaks under it that were coming from the lower valve covers. I read that the cars were notorious for this and purchased Rennline billet covers and new gasket set for both upper and lower sets. Gaskets appeared to be same pattern as the ones on the car. I installed them and was told by tech support to torque to 12-15lbs. When I test drove the car oil was pouring out around the lower covers around 2-3 nuts on each side. After reading 101 project book, it suggests to apply 5.9ftlbs. I am not sure, but my guess is Ii distorted the gaskets and need to replace them.
Question 1). I have a engine number 6401514. I do not think this is a 911T engine from 1973. I believe it is a 3.2 Carrera??
Also the number stamped on engine just above the lower valve cover is 930.105.111.OR
Can you guys tell me the best valve gasket to use, what to torque the nuts to, and what engine I actually have.
I ordered the valve covers for a 1973 911T, and the covers seemed to fit.
Please help!!
