I am currently adjusting the valve clearances on my F22B1 vtec engine.

I am at the point where I have my feeler gauge slid in, a wrench around the nut, and a flathead screwdriver in the 'feeler screw'.

It is almost as if the nut and the screw are freakin welded together.

No matter how hard I try, they wont seem to turn seperately on ANY of my valves.

Am I doing something wrong?

 

Are u loosening the nut and then adjusting with the feeler screw??

 

yes, i have loosened the nut from how it originally was when i took the valve cover off. problem is, when i loosen the nut the screw turns with it and I can't seem to get them to seperate.

 

actually upon further inspection it appears as if the screw will not turn at all. The Nut turns fine, but none of the screws will budge.

After 3 days of research I honestly think I still have absolutely no clue what I'm doing here.

This is my first project with the valve cover off, and I can't afford to pay a mechanic to do it for me and it must be done now. It would be great if someone could explain this adjustment procedure in a way that can be understood.

Thanks for any help you guys can give

 

Pictures would be good, since the adjuster screw SHOULD turn once you loosen the jam nut.

My camera isnt all that great, I cant get very close, but you can see here where i have a wrench around what i BELIEVE to be the locknut.

well now that particular one i have the wrench around is the one that the nut will move freely up and down the screw but the screw itself will not turn.

the one remaining to the right, the screw seems to turn freely but the nut and screw seem to be so stuck together theyre almost welded.

 

some times the adjusting screw gets stuck on the jam nut, but your saying that the nut turn freely, but the screw doesnt?
have you tried unscrewing the jam nut all the way?
with the jam nut loose the screw should move freely as sayd above...
If the engine has not had a valve adjustment in a loong time, then maybe the screw is stuck on the rocker arm.

 

any way to get the screw loose from the rocker arm?

and any way to get the other screw loose from the nut? cause aparently when i loosened the nut the screw just turned with it, therefor making it impossible to complete this task

I use a large screwdriver with a nice clean sharp blade to break them loose.

Your picture shows that you're loosening the proper thing, so I bet it's just stuck. First time adjustment you'll have to break it loose. Just be careful you don't mangle the slot in the adjuster screw. Once the oil gets into the threads, you shouldn't have that trouble next time.

 

thanks for the help guys!!

i've managed to work my way to my 4th valve, but this one's seriously stuck. i've had two people try it and we've literally almost warped the screw's flathead slot.

not that that it's too bad, it's still definately usable, but my point is these last screws are REALLY not budging. pretty much deemed it physically impossible!

now i'm hearing that maybe i should put a few drops of WD-40 or gasoline on the thread and tighten the screw so the gas goes down into the rocker arm and loosens up that gunk.

(By the way, the screw will TIGHTEN, but it wont LOOSEN a single bit more than it was in the first place, even with the nut completely off!!)

is this safe???

Heres what you do:

Go to your local Honda dealership
Get 16 jam nuts
Get 16 tappet screws
Go home
Install said tappet screws and nuts
Do valve adjustment



Meh, it may cost 50-60 dollars to do almost all of them, but if you can adjust *most* of them, and only have to replace a few, you'd still probably be better off doing that than screwing around with non-functioning ones.

 

i would take out the rocker assembly out of the head and leave it overnight submerged is some kind of liquid wrench

 

looking at the pic, looks like your engine's got some oil sludge build up or something, otherwise what kind of oil makes the valvetrain all redish?

 

Are you using that adjustable wrench to turn the nuts??? I would really look into the proper tool before something else goes wrong. That's my 0.02...

Sounds like he's right in his procedure.
