Anybody, somebody, please help! I've had these rockers for over a year now, heck, I even put them on myself! Long story short, I went to adjust them for the hell of it and now the motor runs like crap. I’ve posted a few days ago and tried the reply given to no luck. I check all of my pushrods and none seem bent. I don’t know how to check if a lifter is bad, if anybody has info on that, please, let me know. Also, why do the installation instructions for the CGR rockers recommend installing them one cylinder at a time? Why can’t you do it the way Chevy explains? I would also like to validate what Chilton’s has in the book.
#1 firing position Exh - 1,3,4,8 Int - 1,2,5,7 rotate one full turn Exh - 2,5,6,7 Int - 3,4,6,8
“Remove lash from the pushrod and then I additional turn”
Also, could I have a bad or sticking valve?

Thanks in advance!
Scott

 

I dont know what chiltons says...I do them like this

Rotate engine till #1 cylinder intake valve has just closed, rotate just a little past that point.

Adjust both valves in that cylinder.

Repeat for all other cylinders...

i think i do it like engine boy, i just start at #1 with both valves closed and adjust then go to # 3 and so on down the line. it makes me having to turn the engine a lot more with a ratchet but it keeps my head a lot straighter and less confussed that way.

dont follow the chilton's thats how to set STOCK rockers, follow what the crane instructions say.

 

Oh kids are you going to like this one!
Picture this: Taking off the passenger side valve cover off. Pain in the rear right?
Picture pulling a plug wire out of the cap just enough to cut the cylinder but not enough so it stays under the distributer cover.
Pretty sneaky sis! That was the problem a along. Ughh.
