I have seen some DIY'ers online about valve adjustments, but it wasn't much more than what I have already done.
So here's the problem. I have a 97 Accord, F22B1... not clear on the last number.. but i think thats right(too lazy to go look again...) well the rockers are pingin pretty bad. I opened up the valve cover, placed out lots of towels.... and cranked 'er up. Of course, oil rained out like a misty breaze... hmmm yum! well... I took a tube to each valve and the other end to my ear to hear which onces are pingin... Id turn the car off... set the cam so that the valve was closed on each lock nut I loosed. Then tightened the screw with a flat head screwdriver.... well... needless to say.. the pinging didnt stop. One time I even tightened it to much and the engine was bogging like the exhaust valve wasnt closing(obviously from over tightening). Well... So I loosend it up to the last setting where it wasn't bogging. Still noisy... well.... so I get online to find a DIY'er... and it said something about a special tool.. but that was for the DOHC h22 head.. i dont know if its the same set up or not... mine is a SOHC.. so.. I don't know...
If you guys got any ideas, lemme know. I'm bout ready to pull the head off my other honda and swap them. They are both f22 sohc's. Same head... but id rather just fix it... lemme know if you got any ideas to eleminate the pinging.. its quite annoying.
My idea is that nowhere in your post do you say anything about using feeler gauges to actually measure the valve clearance. If you don't do that you're asking for trouble.
It's more difficult to reach the adjusters on a DOHC engine, so there's a special tool. It's basically a socket with a screwdriver in the center so you can hold the adjuster while tightening the jam nut. On your SOHC engine you can do that with a normal wrench & screwdriver.

Well, I was doing it by ear.. to see when the sound stopped.. but.. it never did. I'm gonna get a feeler gauge... and see if that helps. But still.. even if I tightened it to much, the pinging should have stopped right??
Any suggestions to what I should do if the pinging doesnt stop?? or what the hell else the pinging noise could be?
Everyone be nice to Steven. He's sensitive. I've heard the noise myself and the tap is coming from the top rocker to valve contact even at zero lash. Doesn't sound like spark knock or pinging althought it's not out of the question because he's running a bad O2 with who knows what kind of fuel/air mixture.
I mean we are talking about measurements in the thousandths. I don't see how anyone could do it by ear or just do it by eye because they've done it a million times. At least not correctly. But then again I'm no mechanic so don't listen to me.
