Crooked Rocker Arm?
Thanks
I would take a good look at the side of those rocker arms to make sure none of the needle bearings have come out. I would imagine if any did come out, it could cause the rocker arm to "fall" to one side or the other where it is lacking the support of the missing bearings. Have a look on the magnet on your drain plug. Just an idea... I can't imagine it being a loose bolt- it wouldn't want to run like that for very long before either the bolt came all the way out or the pushrod started to beat the receiver cup on the back of the rocker. Either way, it would be making a hell of a racket and could possibly start to mis-fire.
Just curious, why did you remove the valve cover in the first place?

Both of the bearings seemed to be good when I fixed it. Also, I don't think it was caused by a loose bolt, because when I took it off, the bolt was pretty tight when I started. I have finally just decided that it came from the factory that way and must have been overlooked.
I took the valve cover off because I was making some adjustments to the oil fill tube hole. But also, I took both off anyway just to check stuff over since the motor came from a van that had been in a wreck and I assume sitting for a decently long period of time.

22lbs should be your pre-load.
This is how I did mine:
Mark the top of the vlv with a black marker. Install rocker arm torque to 22ft lb. Spin motor. Check were marker on top of vlv is missing from. If its dead center reinstall to 22 ft lb. If its towards the outside of the motor you need less torque if its toward the inside you need more torque.
Anyone correct me if you have a better procedure.
