Pop both valve covers and figure out which one it was that let loose. Get all you can out. . . take another one and count needles and see if you're good or need to flush. Heads probably don't need to come off to clean up... Saw a case where 3 let loose at same time (bad valve install) and we lost 1... said to hell w/it and figured it was in the filter

Not nearly as big a problem as you think. Like was mentioned, get what you can out, pull your rockers and check them out. That comp upgrade is all you need. LS based NASCAR testing is using the trunnion conversion and stock stamped rockers. 8000+ rpm for 500 miles straight.. all the proof I need.

Pull the valve covers, rockers, and pushrods. Take a pen magnet that will fit down the pushrod holes and go fishing. Make sure you count all of the needle bearings that you find to make sure you got all of them. I think you'll likely find most of them in the head.

Comp labels that kit at $141...

so how does it work? Do you just send your stock rocker arms to Comp and they send them back to you with the upgrades? Or do they send you the parts and you build them yourself?

I've got a kit and I'm about to install it this week. How it works is you press or pound out the stock trunion in the rocker arm, press in a new bearing on one side, stick the new trunion in, press on a new bearing on the other side, snap into place a snap ring on both sides to hold everything in. There is a sponsor on here that is offering to do the upgrade for $200. That includes the kit and installation.

Wow, I guess I'm not the only one to have this happen. Just pulled the plug and 4 of them little buggers were on there. Pulled the valve covers and found the offending rocker arm. Looks like just one. Guess I'll be ordering a rebuild kithttp://images.ibsrv.net/ibsrv/res/src:http://www.ls1tech.com/get/forums/im...h/rolleyes.gif

There's probably 1000 threads about this issue on this site. Haven't read this whole thread or related mod's, but will say that any time a cam mod &/or spring change is done, upgrade the rockers. If this problem has happened on a bone stock engine, then the LS rockers suck worse than I thought.

The only other factory internal components I can think of with needle bearings are the lifters. You can inspect some of them by removing the intake manifold and lifter valley cover.

Did you ever find out where that needle bearing came from? The one larger than the trunnion bearing
