If it has chances are very high for bent valves. Get the rocker cover off and check valve timing on TDC.

turbotrana Member 2,586 Member For: 22y 2m 1d Gender: Male Posted 11/03/15 11:02 AM Share Posted 11/03/15 11:02 AM Can you go thru this failure in a bit more detail, any pics. Pics of the keyway in the crank and the harmonic balancer would be good to. You are not suggesting someone forgot to put the key there??
