Problem with valve adjustment
I'm currently in the middle of adjusting my valves. I'm on the #4 intake valve. I loostened the 13mm nut and now the screw won't turn back unless I apply a lot of force with the screwdriver. The number 4 exhaust screw loostened up without a problem. What's going on here?
Thanks, Scott

Sometimes the screw stretches because the locking nut has been tightened too much. You can live with it or replace it. If you can still get a proper adjustment I'd live with it.

Maybe you have pressure on the tappet, meaning its not at TDC.
