Any suggestions on how to get the compression up or do I have to pull the head...

Driving it that way for as long as you have didn't help it any and may end up costing you a bunch depending on any damage done to the head.

Probably a bent valve but you could run a wet test on that cylinder to verify if it's a ring issue or not. How many miles on that timing belt just out of curiosity ? Ron

I always apply 50lbs or so air pressure to the affected cylinder with the piston at TDC on the compression stroke and listen for the escaping air. It will tell you what to look for when you pop the head, which will probably be necessary. Master, again and still
