Subject:      Maybe I've got this "deck height" issue solved

If you haven't been keeping up, I posted a question regarding deck
heights in the 2.0L Vanagon engines I'm rebuilding.  I measured something
around .02" (with the barrel shims that came with the P&C's in place)
whereas Tom WILSON (I said Watson in previous post) specifies a minimum of
.04".

HOWEVER, Steve Blackham said something to me that got me thinking (and it
hurts!) about the head shim that came with my gasket kit.  It measures
right about .03", and .03" + .02" = .05", right in line with Wilson's
figures.  Since the Type4 engine is the only air-cooled VW engine that
uses the head shim (I think) maybe Wilson was just sloppy in his
writing?  Maybe the real statement is "the distance between the top of
the piston at TDC and the cylinder wall contact point of the head should
be at least .04 inches; for Type4 engines, include the thickness of the
head shim in this calculation."?????????????

Whadaya think?
