Rocker caps

[oniontheoreo]

So I gotta ask if the inner bolts on the rocker caps have a torque, I know the caps themselves don't, I do know that is 1/4 turn to 3/4 of a turn on the caps. I only ask because my caps keep walking of the studs. And I check w/ a square and the rocker studs aren't pulled. And I'm 95% sure I did the adjustment right, but idk.

WHAT VEHICLE? WHAT ENGINE? WHAT VALVETRAIN PARTS?

What are "rocker caps"?

Do you mean the "inner bolts" (set screws) on the aftermarket "polylock" rocker adjusters?

Everyone I know tightens those by getting the adjustment right, snugging the set screws, then backing-off the polylock a little--1/12 to 1/6 turn, re-snug the set screw, then tighten the polylock back to where it was, so that the set screw is turned along with the polylock. The set screw has more "tightness" that way than just cranking on the set screw by itself.

The better rocker studs (ARP) have machined tops, cheaper rocker studs are not machined and don't hold the set screws as well.

It's a 97 5.7 with ls7 lifters and full roller rockers I don't have after market studs (wish I did) but my engine has stock vortec heads. I was thinking blue lock tight (stick no liquid) would help but idk if its good to have that on those polylock nuts. And the studs didn't get pulled, checked them w/ a square

I have the same problem with a couple of rocker nuts,one was so bad I had to put a jamb nut on it,and because of this prob I ordered a set of polyloks.I was going to install them this weekend but an opportunity to go to the gun range popped up so I'll be doing that(never miss a chance to go plink a few rounds).

Sounds like you got your priorities in order!!!

UT I do gotta ask if it would be OK to use blue lock tight in those polylock nuts. I understand if I have to use it liberally, and I do have the stick, so no liquid would run down

You don't have to use it liberally but you do have to completely de-grease the fasteners. Glue don't stick to oil!

I've got a 100 rounds of wildcat I need to fire form and haven't had the opportunity.

I was curious how tight those set screws needed to be so I shot an e-mail to Summit's tech line and asked them.In a couple of days I had a response:15-20 ft. lbs,cool,I can do that.
