Has anyone had any experiences with AVP engines?  I just picked up a
pristine '86 Basic Camper that had an AVP longblock installed 30K miles ago.
Apparently, the engine has dropped a valve seat, I haven't pulled the head
yet, but that's what the PO's mechanic told her.  Anyways, I was going
through the meticulous records and noticed that the engine was replaced 30K
miles ago and the heads were replaced under warranty approximately 5K miles
later.

I have two reasons for asking: 1) if their engines are shoddy, I'll do a
complete rebuild rather then just the top-end, and 2) I'm often asked about
rebuilt longblocks (I won't sell longblocks, only in-house rebuilds) and
although AVP is local, I don't want to steer anybody wrong.

Please... I'm not looking for recommendations for longblocks, just any
experiences with AVP.

Thanks,

Jeff
