There is absolutely no compression on cylinder 5, and very low compression on cylinder 1. All the others are fine. So it can't be the head bolts, because the other cylinders are holding pressure just fine. It's either valves or bad rings. ugh...

I don't believe that is totally true, but IJ had a good idea how to check for a leaking valve.
