I don't know because dealer will not allow me to inspect engine or send me a response to what caused failure. Seems by the sounds coming from the top end of the motor most likely cause is that rocker arm (or possibly a valve train)component failed, noise coming from top end. Of course the failure was just after the 50k warranty by about 17 k miles. So roughly 66-67 k miles. The original estimate was a new long block at approx. 31k cost to me. Eventually after complaining significantly it was settled at 14k plus tax.
