Mushroomed Valve

[dougsorchilla]

To my knowledge, there have been very few valve problems on the K1600. I had a mushroomed valve @ the 16K check. Only one and the more I looked at it, I remain convinced it was a minor manuafacturing error. New Valve sent from the Fatherland and installed within 2 weeks. Now have 63K miles and no other valve issues.

Its pretty strange to be reading about valves failing for what is apparently a simple metallurgical mistake on a piece that is no mystery and made at pretty close to a zero failure rate by every auto maker on earth. I can't remember the last time I touched or even heard of a new street motor with an almost immediate valve failure.

This is the kind of thing that destroys the reputation of a model if it happens to too many. Part of the early demise of the K wedges was the poor cam drive bits that broke motors- another simple item for which there is no reasonable excuse. (The rest is probably that the 6 can be made at about the same cost so provides a higher margin).

The 6 doesn't appeal to me anyway but this sort of problem is one more reason to let others ride it.
