Adjusting the valve clearances in my 1994 Honda Accord F22B1 vtec engine (16 valves).

I am to the point where I have the feeler gauge inserted, a wrench around the locknut, and a screwdriver in the 'feeler screw' I suppose it's called.

It's almost as if the nuts on all valves are freakin WIELDED to the screw.

When I try turning the screw, the nut turns with it.
When I try turning the nut, the screw turns with it.

No matter how hard I try, they wont seperate. Am I doing something wrong?

You just need to make sure you are loosing the lock nut and then tring to trun the adjusting screw. If you are already doing this then all I can say is you must try harder or if you are afraid you are going to break something than take it to a shop. But it should not be hard to turn after the lock nut is loosened.

i had the same problem before too but it was on a different kind head. i just used force and it broke loose but i ended up slicing my pinky really bad because it ran across some sharp metal, almost to the bone.

we use a specail tool at honda that holds the nut so we turn the screw. Try snap-on or napa

use a ratchet wrench! i just adjusted my valves today. make sure you loosen the nut an extra turn before you tighten the screw.
