Well it started with a misfire....i thought it would be a plug or wire
got it narrowed down to cylinder 2 so i pull the plug out it was definitly bad...detonation

put a new one in...still a misfire but not as bad :thumbdown

did a compression check on that cylinder...not holding anything...30lbs

i can here a little metal on metal tap...but it goes away sometimes...
it is not smoking at all or consuming oil so it rules out the possiblity of ring lands or pistons

i think it's a stuck or broke vavle... :cry:

please help with any ideas or suggestions about this or changing the valve would be greatly appreciated... :D

I'm going to start pulling the head off either tonite or tommorrow...

Thanks fellas
 
Well, 2 + 2 = 4 right?
no compression plus metal tapping = bent valves

now dont look at it as god damn it i have to replace the head...look at it as, yes prefect compression once again. the motor is gonan run stonger...so its a plus.
