bought honda prelude with a h23 engine that had 2 bent valves in cylinder 1 So i got a valve job done and the head resurfaced and 2 new valves. So I put the engine back together and it still had no compression in cylinder 1 and now cylinder 3 only has 60 PSI when cylinder 2, 3 and 4 had160.

When I start the engine it runs really rough and shakes and has 60 PSI in cylinder 1 only when running. Also before I put my head back together I saw that there was some rough marks in the cylinder walls so I honed them out and sand it down a little to make it smooth, would that have something to do with it? Maybe I took too much off so the piston isn't getting a tight fit? Or maybe I was sold the wrong head gasket maybe its for a h22 instead of a h23 I don't know if a h22 head gasket would fit on a h23?

So im thinking that the piston ring is bad or something, anyone have an idea on how much it would cost to get the block rebuilt with new pistons or have any ideas?

I tried putting oil in the cylinder to see if maybe it had a stuck piston ring but it didn't do anything

Also thought maybe the timing was off by a tooth or something but the timing is perfect.

 

sounds like broken ring lands/broken piston ring(s). From the way you tried to fix it sounds like this is not a race car/ highly modified engine, so id suggest just getting a new (and by that i mean used) block.
