very odd clues
By John - 06/30/2005 9:07:18 PM; IP 142.177.6.167
If it wasn't for all the bent pushrods, I would have said incorrectly adjusted valve lash on number 6. Too loose. Valve hammers (you heard the noise) and vlave head breaks off....you can see the rest (piston breaking up), but the qty of bent rods doesn't match up. Stock springs are weak for your cam, but floating the valves doesn't seem likely as you say it hasn't been rev'd very much. Coil bind shouldn't break the valve, but will bend the pushrods. With lack of any other clues tieing everything together, it may be a co-incidence......coil bind, plus improper valve lash on #6. If this is the case, your machinist should stick to machining, and not assembly. I always assemble myself, partly becaise I enjoy it, and partly so I dont' have the "warranty fight" should things go wrong. With only myself to blame, I can get on with fixing things. Sorry for the "hindsight" comments, but if you stick with this guy, maybe do the assmebly yourslef, or get someone who has a good history do it.
This thread, so far...
