I should know freaking better! When you have a monster under your hood you pay lots of attention to her! Let this be a lesson to everyone (especially me). Rollers have to be adjusted on a regular basis. The culprit was a loose one. I just kept putting it off and off, coming up with reasons to do something other than messing under my valve covers. Hehehe, guess now I have a reason. The part will be ordered Thursday. I'll keep you informed on how it goes.:( :(
 
Sorry to hear about your gal!!

We are very sorry to hear your girl is sick! Hope shes on all four feet again soon! For now, rub her down with some carnuba, tuck her under a nice warm car cover, give her two quarts of 10w30 and then call the parts guy in the morning. When shes feeling a little better, treat her to some 92/93 octane and long relaxing walk down a curvy road.

STW! Platato :cry

P.S. Has she gottten her voice back yet? My girl has been honking away like a Toluse goose.
 
I use to have that same trouble. I found out I was putting my roller rockers on wrong.

The natural instinct is to adjust the vavle down, then back the polly lock against the main nut. This will loosen up and fall off.

The trick is two fold. One, clean the nut/polly lock with brake cleaner and dry it off from any free oil.

Add a drop of lock tight to the threads.

I like to follow the GM standard procedure of cold setting by rolling the motor around at top dead center, and 180 out of top dead center, then adjusting the selected valves that are ready at that point. I spin the push rod and tighten the main nut by hand until the push rod stops spinning. "I" (everybody has their one method), then turn the nut 1/2 a turn. At this point I run the polly lock down where it just seats without applying any torque.

**HERE IS THE TRICK** Now, you tighten the polly lock and main adjustment down at the same time. Hold the poly lock in synch with the main nut with your alan wrench. Torque the whole assembly down another 1/4 turn. This gives you a full 3/4 off zero lash and that twin twist in a clock wise direction will lock the polly for good, not to mention the addition of the lock tight.


Hope that helps!
 
Thanks for your help

Some of the guys I met here in the local Corvette club are going to help me out. At the same time we are putting in new GM 3.54 gears. I'll let you know how it goes.
 
Ditto, but about two weeks ago. A PVS roller tipped rocker "rollered" right off the edge of the valve stem. Snapped one push rod, pretzled the one next to it. I was lucky in that was the only damage. I think I'm looking at guide plates soon. Fortunately, I machined for screwed studs when I prepped the heads. I may only have to pull the intake to catch the chips from through-drilling the push rod guide holes in the '416 heads. My other option is Jessel shaft rockers, but a slightly modded LM1 just isn't worth that much $$$. ;)
