Ok I adjusted my rocker arms the same way I have done before and I drove about 2 miles down the road when a horrible clanging chattering started. I pulled into a friends house and we tore apart the topend and found that two arms fell off and almost all the other adjusting screw came loose...WTF Well we readjusted it and got it back together but now theres a vibration and sounds like its missing. Checked all the plugs, 1# plug has a little gas on it but I've put 3 different plugs in and it hasn't changed. Also when I turn the car over theres an obvious dead spot/miss. So....
Bent pushrod?
Bent Valve?
