Welcome back:
Okay, the one side has 30 psi. Now you made a good point. If a valve is bent and stuck open, you would have no compression. So, I suspect it is off time but not enough to bend anything. The 30 psi may be an indicator that the valves are not closing early enough or opening too soon. Thus, it can't build compression.
To check timing before you remove the chains, you will have to see if all the marks align, which may require several crankshaft rotations to happen. I am going to provide the directions for replacing the primary and secondary chains. Just fyi, this isn't going to be the easiest thing you have ever done. In fact, it can be frustrating.
_____________________________
Here are the directions. I will break them down this way: Primary, Secondary Left, and Secondary Right. All attached pictures will correlate with the directions. Note: The secondary left must be installed before the right side.
