2001 CRV low compression on cyl 1



My 2001 CRV hasn't been running quite that bad, rough idle but not stalling, but has P0301 code and flunked inspection. They said low compression on cyl 1. I see online how valve adj issues occur on this engine, so I've got a manual and hope I'm not going in over my head...!Never did something like this b4...Timing belt looks decent, but dunno how old it is. Looks like it's got some slack to it. Book says to tighten it 3 teeth...? Will adjusting the valves be sufficient, or can I assume that, because the compression is bad, I've actually gotta replace a couple valves. If I'm down into it that far, should I be wise and also change the head gasket, or is that overkill? They didn't think I had a leak in my intake. BTW, When I first got this from a dealer 2 yrs ago, at 130K, it died a week later, and they replaced the cat convrtr, no charge. I suspect it might've been due to the valve issue - dunno if they adjusted em. Now at 175K.
Any advice on how I should proceed?

Dickdriver, I would check the valve lash first,you may just have an exhaust valve too tight.Dont delay and keep driving it or you will burn a valve. The timing belt will not cause the P301 cylinder misfire code. There are several good posts on here with pictures and instructions for doing a valve adjustment. After adjusting the valves, clear the code and see what happens. If the code comes back then perform a compression test.
