check your oil pressure with a mechanical guage - rockers are the last things to get oil - if pressure is low they will make noise - check it NOW!!!!! or risk bearing failure in the near future
i just assembled mine ,i have motorsport 1.7s and they are noisy as hell,sounds like a flat tappet cam,had them checked and rechecked to see if i did something wrong,npoe just noisy.
No problems with the oil pressure. Other than the noise and some PCV and crankcase pressure problems the motor ran great. The motor is partially disassembled now and there is not visible wear in the valve train. I guess it is just a noisy set up.
