I spoke to my tech today and he clarified what he thought the problem was. I am not mechanically inclined so half of it probably went over my head.

It has a bottom end noise that's been there for quite some time, they speculate that it's either a connecting rod, or a journal bearing. That is separate and preexisting from my new issues.

In relation to the compression, they do in fact suspect a timing chain jump. They did pull the cats and they verified they are ok. Their next step is to measure the backpressure or something, once again over my head. They are pretty confident that this will point to the timing chain.

They did mention that there is a new updated tensioner, and that the old tensioners caused a lot of problems with jumped timing chains.

I will know more Monday. My question is by running it the way I did with the timing chain jumped, is there a possibility I might have bent some valves as well?
