Sorry I wasn' too clear..

4 out of 5 pistons have motion when halfway down the
bore. I havn't measured the pistons/cylinder wall
clearance but it is definetly > 0.003" for a few of
these pistons which is the Audi wear limit according
to the Bentley.

Funny thing was, all cylinders still made decent
compression for a MC-1 engine (~120 psi). I guess I
got an anomaly on my hands.
