Help With Rocker Arm

[louieb]

Might be that the push rod guide plates aren't lined up right causing the pushrod to slightly shift off to one side, which will cause the rocker arm itself to be off to one side. They were talking about it on one of the car shows on tv and said that sometimes when they're torqued down from the factory, they'll shift to one side. Best way to fix this is to loosen the guide plate back up, put something between the plate and somewhere on the head (to keep the guide plate a set distance that won't move when being torqued) and then tighten the guide plate back down. If I find a video of it, I'll post it for you and you can see if that's what's causing any geometry issues.

Yea this time i didnt put a half turn pre load. maybe a1/8 to a 1/4 max. finger tight, and just a tad more. It seems to be running better geometry. no more binding. but i have a little bit of extra grumble in the exhaust when i shift. it also sounds like its laboring a bit up hill.

one thing for sure is afr rocker studs are known to break even with good geometry and motor running fine, i broke one on my afr 185s the fix was 8 new ARP studs problem solved good luck
