That's a receipie for a broken rocker stud. DON'T DO THAT!!! The stress it puts on the threads, along with the hammering of the cam on a stiff valve spring.... The stud will snap right at the bottom of the nut..

Like 68post suggests,,, set the preload and set the polylock with a allen wrench WITHOUT TURNING THE ADJUSTMENT.

And I agree, cut your oil filter open and see if it's loaded with cam debris. If so,, just get yourself a hoist and get started plling the motor. Bearings are trashed, oil annuluis are all full of debris.. If you just change the cam, you just eat it up wit hthe ground metal in the engine. Bearings are soon to follow.
Still playin with trucks, even at my age!

When you're dead, it's only a problem for the people around you, because you don't know you're dead.
.....It's kinda the same when your STUPID.

I just did my taxes and reviewed my SS statement. Thanks to the current administration it looks like I will only have to work till noon on the day of my funeral.
