Wow took me 2 mins wat I was trying to do for an hour yesterday. Thanks Zul8r. I got the spocket off and more bad news be locating pin and sprocket was on perfectly no damage so now I'm out of options. My guess is the head has to come off for me to see wat the problem for low compression is. Is it possible to do one head at a time or even one head gasket? Is there a way to tell if I have a bad oil pump? I really hope it's not piston rings because I don't know how I can tell if they are good or bad at this point. Also when I took the intake sproket bolt off pil came out is that normal? Any advice on where to go from here would be appreciated thanks again
