[Vwdiesel] Piston fit in block ---- ( when reboring ).

[James Hansen]

Gavrik was concerned about ring seating and oil consumption  and I heard the
German say that VW diesels are not a straight bore.  It is like cone or
funnel.
The top part is smaller than the bottom. ---Is that true ?.

___

This is how sleeves (bore) for ABC model airplane engines are made
(aluminum, brass, chrome) The tapered bore on a new engine just allows for
the thing to be turned over at tdc, while being relatively friction free for
the rest of the time.




The 2 thou piston fit I got from a friend. That is a tightie.    My GM book
for
the V 8  say 5 thou.

____
 Buddy has some Keith Black hypereutectic pistons that are supposed to be
some unreal thing like a one thou fit.  yeah right. Not for my engine... I
can just imagine the big squeek those will make.
