Last spring the 380 ate a timing chain guide rail on the left side. Bent some valves, put a hole in #6. Finally got it back together. Thanks for all the help and advice.

Cranking it with the starter all is good. When it is running I'm getting a loud metalic knock on the right side, sounds high on the engine around #1 & #2. Did a compression check. #1 is 140, the 2-4 are around 180.

I don't remember exactly, but I don't think the valve timing on the right side was off during the timing chain incident so I don't think I have any bent valves on the right side, but oboviously something is going on.

Any ideas?
