<VV> Engine Problem....What to do?

[J R Read_HML]

Hey Mike...

Good to check things out in advance, but if it is either rings or valve
seat, the head still has to come off.  Once that is off, it is a short step
(and a very prudent move) to visual inspection of the rings AND the pistons
as well.  IF cracked pistons are found on one side, now it is time to look
at the other side as well.  Also, the engine still does not have to come out
for rings.

With a 90lb difference between cylinders, I'm even more convinced that it is
valve seat, but you are right... it COULD be rings.  I just think that the
differential would not be so great between the bad one and the others if it
is just a cracked ring (I could be wrong on that).

So, who lives nearby that has a "loaner head" for our friend so that he can
drive at least ONE of his cars while the head goes off to the machine shop?
