I've had my H22 in my Accord for almost a year now...one night I missed a shift went from 3rd to 2nd and messed some valves up in the head. I thought no problem, I'll just get new valves,springs, ret and a port job, which I did. The guy who did it had an extra H22 head sitting around from some kids motor that he blew up with too much n2o but anyway, he did all the work to that head and once it was done, I just traded heads. Anyway I got the motor all together drove it about 3 months and couldn't get the valves to stop making noise. I eventually take it to a friend who works for the guy who built my head and he tries to do a valve adjustment and it fails b/c we notice the cam has been badly worn away on the #1 cylinder exhaust side. He and the guy who built my head said it was b/c of lack of lubrication b/c I had the wrong dipstick in the car and not enough oil. Anyway I bought a whole another used head and replaced the cams and that one set of rocker arms b/c that was trashed too(only the #1 cylinder exhaust side). I get it back together and now as I do another valve adjustment 3 weeks after I just replaced my cams that same cam lobe is already showing signs of wear?!?!?!? I have plenty of oil in the motor so why is it still eating up that cam lobe and rocker!?!? I've left a message on the guys machine hopefully he'll call me. But anyway, does anyone have any idea what could be wrong, its all aftermarket valves, springs, ret....my neighbor said it may be the wrong spring or too much tension for it but the guy who built it swears its 100% perfect...what the hell do I do?!?!?!?

What kind of cams are you running? Are the springs aftermarket as well? If the spring pressure is too high You could cause a metal to metal situation to occur. I have seen this type of damage done when improper springs are used. Also, what is your oil pressure like under load in the uper RPM's? if it isn't high enough (at least 80 psi) around 8000 RPM then you may be starving the head from oil this can also cause extensive wear. I would check atleast the oil pressure first and then find out what type of valve control (springs) you have and go from there.

Have you thought about how you are lubing the cam on initial startup. This is real critical to how a camshaft wears. You must use the proper breakin lubricant. Another thing-I agree that you need to take a very close look a the spring set. Honda is very particular about mods to their engines (chassis too). If you are running a spring rate that the cam was not designed for-there is no amount of oil that will save it from failure. A very slight increase (10-20 pounds) is probably OK. Also, the H22 is not really designed for sustained use at 8k. Hope this moves you in the right direction. One last thought-get all new Honda springs and retainers and match them for all cylinders.
