Valve lash value which one to choose?

[RIQUE]

Allo Allo mates,

I will be adjusting valve tomorrow and wanted to know what to value is recommended. 0.010 or 0.012? are these values affected by altitude?

Thanks oh yee wise ones. Enrique

On an engine with some miles on it, .010 will be a little quieter, and gives you a little more duration of valve opening. On a new engine, I'd go .012 to allow for break-in wear, otherwise I use a generous .010 on all my M30's.
