Comp 918 failure caused #6 piston to disenegrate :(

[gottaswapup]

Well I took off work yesterday to tear my motor apart and found the #6 exhaust valve spring broken, then once i got the head off I looked doen in the block and where a piston is supposed to be i found one chunk about the size of a chicken nugget the rest were so small they fell into the oil pan im assuming. When it happened it completely chewed up the head and ate the spark plug. looking down in the cylinder hole u can see that it chewed up the crank and the cylinder wall was demolished.

Well my dad said take this negative and turn it into a positive..
Hello reman longblock LQ9!!lol

Were these the original design 26918s, or the recent, higher-rate 26918s?

All the chevrolet geared performance websites need stickies on comp 918s. After reading about the first ones I said no way am I gonna risk my motor. Patriot dual golds for me.
