[s-cars] The dealer's great deal

[Fred Munro]

David;

In addition to Igor's advice, I'd recommend at a minimum to have the valve
guides replaced on the obviously damaged valves and the piston removed and
Magnafluxed, paying particular attention to the crown. It wouldn't hurt to
inspect the rod & bearings on this cylinder as well.
Igor's advice is good and would make a good test for obvious damage to the
other valves - if they leak brake fluid, change them. They're not as
expensive as pulling the head to do it all over again after 10,000 miles.

Good luck!

Rich,
the fact that hte rest of the valves do not appear bent doesn't mean
anything. I have just BTDT with my wife's A4. A sheared timentg belt
resulted in ALL exhaust valves bent.
The other valves may be bent as well and you will get poor compression
and rough performance in the end. And whoever will be doing the head
work after he is done and ready to install the head on the block MUST
turn it upside down and fill all 5 combustion chambers with brake fluid
and wait for an hour to see if it leaks. In my case, after ALL the
valved were replaced and lapped by the pedantical Yours Truly, 2 out of
4 cyliders leaked the brake fluid. Which necessitated re-lapping of the
relevant valves. If there is as much as a hairline skore on the seat or
a speck or lapping compound grit stuck between the valve and the seat
the brake fluid will find its way. This is the old mechanic's trick used
in my youth Russia

I would positevely not agree on anything less than ALL of the valves be
replaced.
