Wtf!!!!???!! Help Please!!!!
I am in the middle of installing some roller rockers on the LT1.... On the driver side i am having trouble with one of the rockers.... It keeps falling off, eventhough I have set zero lash and given it its 1/2 turn..... I have tried putting another rocker and it does the same...????? any ideas please....... thanks

I have tried again and the same thing happens.... It idles ok for about 20 sec. and then for no reason the rocker just falls off..... Can anything be damaged if this keeps happening??? I have also noticed that when i turn the car on some of the rockers lean kind of sideways..... They look as if they are going to fall off, but they do not.....

Are the rockers self aligning or Guide Plate Style? If they are not self aligning you need to make sure you install guide plates. You are setting zero lash when the lifters are on the base circle of the cam right?

The rockers in the link don't look like self aligning to me. There are notches stamped on the tip of the OEM rocker to keep it on the valve stem. I don't see any alignment washers like my Cranes have for aligning. Correct me if I'm wrong but the rockers in the link need guide plates.

The picture is "generic". According to the table of part numbers, and "Note H", you need the part # 1417-16 (1.52X) or 1418-16 (1.6X) for self-aligning applications. What part number do you have?

If your engine was running and 1 rocker fell off, one cylinder would die. If a few rockers fell off, your engine would die. Then you would have no steering etc etc etc.....
How can you not know the part number of the parts you received????? Even if you threw away the box they came in, don't you still have the bill?????
How did you identify them to Comp Cams without a part number???????
If you have actually received NSA then you can use guides like was mentioned above but you will have to get hardened push rods to survive.
My feeling is you assembled them wrong and that's why they are leaning. Guide plates won't stop that problem, only a rotational problem. The reason they are falling off is the nuts aren't lock nuts, they are probably standard nuts.
Did you buy these from an individual or a company?
