<VV> yup, It's bad (Turbo dropped valve seat)

[Dan & Synde]

Hi Lonny,

When you say newly rebuilt, were the head redone including new valve seats
or just a regrind?  Were they done by a reputable shop that has experience
with aircooled motors?

I came to the conclusion years ago that if I didn't know the history of a
set of heads that I was better off just getting all the seats and guides
replaced and get it over with, even with non-turbo heads.

If the seats were replaced and done by a reputable shop that does aircooled
motors and you havn't overheated the heads then I'd just get the one
cylinder fixed.  If the pistons are forged, then just like Ian said,  pick
out the pieces and smooth over the dents to take the sharp edges off.  As
long as the ring land didn't get crushed and they're forged you should be
okay.

Sorry to hear about your problems,

Dan Kling
