7.3 powerstroke burnes valves at 100k+?

A local Toyota service manager was telling me that the 7.3L
Powerstroke tends to burn valves shortly after 100k (after the
warranty period, of course). Can anybody verify this?

Thanks,

James

James,

I have the 7.3L engine approaching 100K, so I'd be interested to see
responses to this as well.

My auto mechanical skills stop at the real basics, so could you tell me
what a "burnt valve" is and how I would know if my truck had it?
Thanks.

your toyoda dealer is blowing smoke up your butt to try to get you to buy
one of his junkers. the powerstroke is known to go over 400,000 miles with
only regular maintenance.

Thanks, that's the kind of pointer I needed. At first blush I didn't
see anything to verify the contention, BS is a likely candidate.

This will only happen effect you chip the engine and boost the EGT which
is hard on the valves. If left stock it should not be a problem.

high EGT will melt the aluminum pistons, not melt the steel valves

How the **** would a rice rocket slant eyed salesman know anything about a
REAL truck? And for that matter, WHY were YOU talking to one?
