300 TDi HEAD INFO PLEASE

Range Rover Blues:
Yeap I went back to the same.  I did have some data but it's not at hand, the valves don't get anywhere near that close though.  If you are worried then cut the valve seats to match the head skim.

I've measured both ours and annoyingly only one piston dictates the gasket thickness, the other 3 could tolerate a thinnner gasket.  On my sister's it;s one side of one piston that takes i into a 3 hole gasket.


BTW for those who don't know, 1 hole is the thinnest, 2 hole the next, 3 hole the thickes t used in production and no holes the thickest service gasket readily available, the thickest of the lot typically needed on blocks that had been refaced.

Don't have the thicknesses to hand either but 0.2mm between sizes rings a bell :-k
