Valves

So a friend and i decided it would be a good idea to adjust my valves because they were ticking a bit. So we get the valve cover off, and while we're at it we cleaned it up and painted it a cool graphite color. Anyway, we set piston # 1 to TDC and take out our handy feeler gauge. All of the valves were way too tight and none of the valves seemed to be set at the right tolerance. * side note * we could grab the top (where the screw is ) and wiggle it side to side on some of them. Is this normal, i wouldn't think something should move around that much up there. Anyway, we adjusted all of the valves to the right specs and put everything back together. Guess what, the ticking is even louder now. Not just a bit, but ridiculously loud, and the strange thing is, the engine is running smoothly, just loudly. Any help would be great guys.

Umm, maybe. Whatever sits between the cam lobe and the valve tappet. But my friend and i opened it back up today and double checked our work. We said screw it and threw the feeler gauge out the window because the stock specs were not working. We tightened everything up so it only moved slightly from side to side. Cranked it and it started right up. No more ticking, no hesitation, in fact, it's running smoother than it ever has. It's really kind of weird.

I think the cap if for when the metal heats up it expands. The gap is meant to keep it from touching too soon. So might want back them off just a lil bit.

you have to have a feel for what the correct spec is.

when you use a .007" feeler gauge, the tougher it is to drag the gauge between the rocker and came lobe the closer to .007 it is. When it becomes so tight that the feeler gauge no longer moves, the clearance is .007. If the .007 is really loose, put the .008" gauge in there and see if it fits. If it fits, the clearance is not in the .007 spec, its above .008"

did you let the engine get COLD before doing the adjustments?

if the ticking got louder, then the valves are too loose and need to be tightened. They are making a ticking sound because the lobes on the cam are skipping on the rockers.

__/---\__ - lame excuse for a cam lobe

if they are loose, the cam will ride the base (the part with no lift) until it reaches the "ramp" of the cam lobe. When it gets to the top of the nose of the cam lobe, the cam with jump the gap (the plateau of the cam lobe) and will land back on the rocker making a ticking noise.

remember that you have to rotate the engine counterclockwise while doing the adjustments per cylinder.

each 90 degrees of cam gear rotation will represent the following:

arrows pointed straight up - cylinder 1 TDC
arrows pointed left - cylinder 3 TDC
arrows pointed down - cylinder 4 TDC
arrows pointed right - cylinder 2 TDC

Yeah i know all about that stuff. Waited for it to get cold, did the rotations and ****. But when i set them to stock specs it ticked loud, and ran ****ty, now it doesn't. I went by the specs in my manual. but if anyone knows for sure the specs then let me know.

H23 clearence Intake: .07-.11mm or .003-.004in
Exhaust : .15-.19mm or .006-.007in
F22 clearence Intake: .26mm +.02 or -.03 .01in =.0009 or - .0012
Exhaust: .30mm +.02 or -.03 .012in =0008 or - .0012

I highly sugest backing the rocker off and properly adjusting the valves because when the metal heats up it will expand and hold the valve slightly open.

Haven't posted in a while but I need some help with buying new valves for my H23a...

The only valves I can find are for H-Series "Vtec" engines... and on ebay they only list ones for the H22.

I'm wondering if the H22 valves would work in my non-vtec H23, and if not, does anyone know where to find some reasonably-priced H23 Valves?

I don't want to spend more than around $200.

Thanks for the help!

I meant to say my budget is $300.
