It won't hurt if I tightened the rocker down 1/2 instead of 3/4 right? I adjusted them with the engine running; loosened til clacking, tighten just enough to stop clacking, and went 1/2 turn instead of 3/4. When I loosened them they were turned down 1 to 1 and 1/2 times why so tight? The car has 102,000 miles and has never been adjusted could that be why? Also the engine runs so incredibly smooth now it's pathetic!!

 

1/2 turn is fine.

 

Suprised you didn't have atleast a loss of power. Someone tightened my buddy's rocker arms too tight and it would barely spin over.

I did experience a loss of power because now it revs a lot quicker and I have almost zero backfire. I always thought loose rockers clicked and did not realize too tight ones do too.

 

Loose rockers clack hehe.....normal rockers tick.
