Replacing only one valve assembly???

A guy at the dealer today (not an employee) said that he had 50 hours on his son's 07 when one of the valves went south. He didn't say which one, but he said rather than spending big bucks on a entire valve job he just replaced the one assembly since the rest hadn't moved.

To me it doesn't seem like a good idea. I'd say if you have the head off do the whole job. I'd maybe consider this with 10 hours but 50? Anyone tried this?

I don't see a problem w/ it. I ain't no Ron hamp, but I'd do it if circumstances demanded.

I thought it was total BS at first, but now I'm hoping to hear from some more people that have tried it.

It`s a lot of work to do again when the other valve fails.

Just something to consider.

That was my first thougth. The exhaust valves don't move much do they? Maybe just do the intakes and have 2 seats cut if they go out prematurely. I think I'm good though. exaust .011 left intake 004 and right 005, the same as the day I bought it. I wonder if its worth shimming the 004, the manuel says +-001 so its still in spec and hasn't moved in 9 months.

It`s a lot of work to do again when the other valve fails.

I agree w/ that statement. Kinda a reason I do all new when I do a top end; I'm in there, get it all done.
