Too true, Gordon.  Or at least it used to be.  VW has a lightweight hyd. 
lifter now, but I will admit I do not know the weight of the mechanical 
one.  The normal hyd. lifter is like 80 grams, and the newer one is 
something close to 50?  I searched VWV and did not find the thread I was 
looking for.  It is something like 8 pages long...  Long story short, 
IIRC it is the newer 2.0s lifters...
