Removed the valve cover. The upper chain guide had been taken off already.
All of the valve train gear was fully intact.
Did a compression test. 155 150 145 150 So doesn’t look like there are any bent vlaves from the over rev.
Did a basic stethascope check. Noise is coming from the lower end, rear of the engine.
The beat of the noise doesn’t coincide directly with the RPMs.
I had a family gathering tonight that went longer than I thought, but tomorrow it will be ripped apart.
I’ll keep ya’ll updated
