sorry guys my buddy has a b16 out of a civic :rolleyes: but anyways, we have engine out and the previous owner of the b16 said that one of the valves in the head are screwed, so we have the head off how do we check which one it is ? any info would be appreciated if positive info thanks guys:dsm: all the way
 
First, the cams have to be out, otherwise it will hard to tell. If you still can't see which valve is bad, stand the head up on its side, resting on either the intake ports or the exhaust ports. Fill each upright port with liquid (rubbing alcohol will work good because its thin). Watch the combustion chamber on the head (where the valves are) and see if anything is leaking past the valves (into the area where the cylinder and the piston would be if the head was on the car). A tiny bit is acceptable, but a lot is bad. If nothing leaks, flip the head over and do it again.

Good luck.
 
but its a good idea, now that you have the head removed to lamp the valves... just to be 100% sure that all your valves are sealing correctly, cause sometimes all the valves look okay, but it could be a milimetrical tiny little scratch on the valve seat that your eyes can't detect, but the compression will.
It's not hard, just go to autozone rent the valve spring compressor loaner tool to remove the springs and locks, buy some valve grinding creme, about 4 bucks, and start lamping, just remember to do it one by one, and leave every valve on it's original place...
if you need any help on "how to" just ask...
