It is a Stock Gtir motor with a Nistune ecu. The other night it popped out of 2nd gear around 4500 rpm and free revved and the rocker arms are done. 6 out of 8 rockers a busted up or out of placed, Funny thing is I did not notice any metal to metal noise when trying to start the motor up again.
So my question is should look at a full engine rebuild or can I just perform a top end rebuild?
I was thinking of performing a compression test and visual inspection with a borescope. All of the springs and retainers are in place.
What advice do you all have on this?
