[Vwdiesel] Piston Rings

[Erik Lane]

Best is to measure your bore and make sure that it's in good enough
shape to not be bored oversize. Or have you already checked that? To
do it well you need at least six measurements per hole, two
measurements at every level. One longitudinally along the block and
one 90 degrees offset to that. Then you do that near the top of the
cylinder, midway down, and near the bottom. That shows if it's gotten
egg shaped or distorted along the piston's path of travel.

If it's all good then just replacing with whatever size your piston is
should be good. (Though you should also get some feeler gauges in
between your rings and the ring lands to check for wear there.)

All this depends on the story with what's going on with your engine.
Are you building it up new, or repairing a bad ring problem, or what?
