After reading the haynes manual and some older posts in the archives I am not sure what is the proper valve clearance for a 1.8 L. Is it .006 intake .008 exhaust or .006 on both?

Lemme see. The factory used them in 356s from about 1963, through the SCs for sure, and maybe later. You're gonna go with a smaller stem diameter (less area) in an area where heat transfer is what it's all about. I have never had a problem with the sodium filled valves, and I've worked on Porsches for 32 years +. The problem is HEAT, and HEAT TRANSFER. Infrequent valve adjustments, timing, cr*p on the fins, low oil, worn valve guides, cracked heads, the wrong plugs, and lean running, but not the sodium filled valves. SS valve technology must have come a LOOOOOONG way, because we tried 'em in T1 motors 25 years ago and were lucky to get 10000 miles out of them before the tips cot concave and the heads tuliped. How much you want for those old valves? Are the stems worn? The Cap'n |
