how much of the stem is still attached to the valve?my guess is that whatever came in your intake got caught in the valve, hanging it open.then when the piston came up, it smashed it breaking the stem and dropping the head of the valve into the cylinder.would be interesting to know ow far up the stem it broke though.sorry to hear about this, it always seems to happen just after they get back on the road too...-Owen
Bought the IC from a member on here used not sure of the brand. There wasn't much stem on the valve but you can see on the bottom of the piston it cracked it.I may try to find a way to install some screen to catch any loose *** before it gets to the engine. As long as it its self doesn't become loose and cause probs.
fek me!
