As the title states, can a semi-loose rocker arm cause a misfire? I've had a misfire issue for quite awhile w/my car on cylinder 7. Yesterday I took the valve cover off and pulled the pushrods from 7. They looked good, but when I was taking the rocker arm off, it didn't take much for me to loosen the bolt. Specs say to tighten them to 22ft. lbs, I tightened them yesterday to 23, any problems with that? Thanks.

If your rocker was loose to the point of setting an SES, it would have fallen off before you could even find your A-Tap to diagnose it <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> , I would remove the rockers from the DS and take a straight edge across the valve stems to make sure you don't have a bent valve thats causing the problem, also, inspect all the PR's to ensure there all straight as an arrow. 23 Ft lbs is acceptable.

Good luck!

Joe.

Pushrods are A-Ok. As far as everything else goes, ya lost me. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" />

With the rocker arms removed all of the valve stems should be at exactly the same height. You can use a straight edge to determine whether this is true. Any valve that is below the others is bent.

Because that's the only thing I can think of if you pull the rocker arms off. You have the pushrods sitting in their spot, and the springs in their spot. I checked to see if the springs were movable (as in a broken spring) but that wasn't the case.
Sorry, gotta work w/me here, I'm a newbie at this type of thing. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" />

I had the car autotapped after the pushrod incident and I didn't have the misfire on 7. Didn't notice the misfire until our buddies at Xtreme "tuned" the car. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />
