Hey Gang,
I finally got my 91 Camaro RS with a 305 purrring but now i hear a clicking sound coming from the valve rocker arm.I adjusted them after i rebuilt the engine now i think one of them came loose because i have a rough idle and a clicking sound coming from the valve covers....I only have a rough idle..Driving the car is perfect besides the rough idle....So my question is how do i keep the valve rocker arm bolts tightened?Can i use locktite or do i use the nylon nuts so it wont loosen itself again...Or do i use both?I dont feel like taking off the valve covers ever 1K miles....All and any info is greatly appreciated..Please HELP ASAP...

 

If you only set the valves once after you built the motor, that's fairly normal. You usually have to reset them again a few thousand miles later...and generally after you set them the second time, they wont really come loose. Thats what I hear anyways.

Thanks for the info Nixon and Token....I read that link before but it really doesnt state on whether or not I should use locktite or nylon nuts for the rockers....I know i adjusted them right but like Nixon said,i probably have to readjust them....I was just wondering if i could use either or both methods to keep the valve rocker arms in place and so they dont unloosen themselves over time

 

I say do em dry... they'll need to be adjusted every xxxxx miles...

 

what do you mean do em dry?sorry...

 

They are a special nut. You can't replace them with any other kind. You could go get new ones at the dealer, but that actually involves money.

Just adjust them normally. If they seem loose, like their "lock" function is worn out, add a jam nut on top of the actual rocker nut. They're 3/8"-24 (fine thread).

 

Thanks for the info...So i cant use an arrow nut that is a 3/8-24 fine thread from OSH(Orchard Supply Hardware)?Thanks once again.

 

No.

The bottom surface of a rocker nut is made so as to be a bearing surface where the rocker ball (a moving part) rotates underneath it.

Just jam them with some regular nuts run down on top of them.

 

Thanks for the info...Im going to the parts store to get them now....3/8-24 fine thread?

 

Can i put locktite on the jam nut?Because isnt there still a chance of the jam nut coming out and wreaking havoc on me?

 

if your really that concerned you can get locking nuts for em.. they work pretty good never had a problem with mine.. they use a little allen screw in the middle of em that jams down on the stud locking the bolt in place

 

No need to fool around with Loctite

 

thanks to everyone that has helped me out...I got em tightened down and just left them the way it is...She is PURRING!!!!!!!!
