Project XXX AWD WHP Or Bust!

Did you pull the rod and main bearings on the replacement motor to see if they had any damage PRIOR to installing? Pull pistons? Check rings? Or any of the clearances?

The intake cam timing had to be out of sync with the crank for something like that to happen. Unless you were doing 8k+ pulls on stock springs with crazy cams.

One more thing, when a rocker comes off a lifter, 99% of the time that valve is toast already. If you had checked compression instead of driving it again, I can pretty much guarantee you would've had 0.
