Adjusting the valve clearances in my F22B1 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 have to get either a wrench or I think snap on makes a special tool for it. I took a 10mm wrench and heated it with a torch and bent it, after bending you have to use the wrench to hold the nut down. Then when your holding it you can use the screw to tighten and loosen the screw as needed. If the intake specs are .007-.008 make sure to tighten it down using the .007, it takes a lot of practice but you have to get it just right so the .008 wont fit, and the .007 will. Have fun. I'll take a pic of my wrench I made when I get home.

 

or you can take a 10mm deep socket, and a cheap like 9/16 wrench, the one that will just fit around the outside the socket...use a hammer to "mate" the wrench around the socket...done...7 dollar version of a snap on tool..works great on my prelude, cus it is a total mofo when it comes to valves...

DUSTIMUS...EMPTY YOUR INBOX...LOL

 

I had the same problem with the 1.5L in my 95 Civic; the problem was caused by too many years with too little attention to the valves. As a result, a thin film of sludge built up in and around the screw/nut of each valve adjuster. Like you said, the screws and nuts seemed welded together! If I held the nut steady with a wrench and tried turning the screw then the slot in the screw would deform. The solution: heat each assembly with a small propane torch for 5-10 seconds, being careful to keep the flame moving over the entire screw/nut assembly. This will cause the nut to expand slightly, and will also soften the sludge. You will then be able to turn the screw while holding the nut steady with a wrench. It wouldn't hurt to take the screws and nuts off at this time and clean them thoroughly before finishing the job.
