Stuck Valve? Options

[mark95turbo]

OK. So im pretty sure ive got a stuck valve. I first heard it when I was coming home from work this afternoon. It sounded like something rattling or something hitting against the radiator fan. Well I got her home and started listening around. I took a short piece of 1\4ID pvc tubing I had and held it against my ear and the other end against the motor and other various parts under the hood and tried to track down where the sound was coming from. It seemed to be loudest right around the timing belt cover so I took the top part of the TB cover off and it seems to be coming from behind the cam gears. So I'm assuming that I have a stuck valve. The only thing that confuses me is that the car runs fine and at higher RPM's the noise goes away. Does this sound right? I noticed on the drive home that I only hear the noise at certain RPM's but I never truely got on it and barely got above 0 PSI. I of course havnt driven the car since. I'm gonna run some valve cleaner through it tonite to see if that makes any difference. Anybody have any suggestions\advice? Thanks!

I havnt ruled out a rod knocking. I havnt really ruled out anything, lol. I was just kinda starting from the bottom and working my way back up. I'm gonna get and Oil Pressure Gauge and change the oil then check the pressure. The oem Oil Pressure gauge doesnt work (most of the dash gauges dont) and then ill go from there. I'll post and update when I find what is wrong. Thanks guys! I'll also do a compression test but I'm assuming that the valve is frozen shut if it is, so its not like a compression test will do any good in that case.
