Motor 1 was cam bearing, remember, the cam hit the bearing when I bumped my hand and it cause the cam to drop.
Motor 2 was a rod bearing, that was confirmed. Bad luck, bad prime.
The KR issue started well over a year ago in engine 1. I was only from time to time and only a few degrees. Mostly around 45mph in 4th gear, shifting to 3rd cleared it up. Slowly got worse over many months. Tuning seemed to clean it up and then it came back. When I decided to rebuild the cam bearing was going out and I found metal in the oil, that'* when the oil pressure dropped a bit.
Engine 2 was different. Bad pump prime, lesson learned, always use a mechanical pressure tester to verify pressure is there.
How can it be true knock? There is no part of the engine left from the first, or second engine other then the PCM and knock module.
I did have bad run out on the flex plate, I showed that with the dial indicator. Also, I had a bad vibration that I could feel and it shook the seat. That vibration is gone now.
