I got and H22A1 swap in my 93 Si... I have a knocking noise almost sounds like its coming from around the timing cover/crank pulley area... The motor was taken out of a good running car and dropped into mine and was never opened or disassembled. Anyone know what it might be? Also i got the AC compressor hooked up and running but one of the lines is not connected due to a snapped bolt. I thought the noise might be coming from the pressure in the AC comp. but6 it doesnt sound like its comin from there.... the noise comes and goes every now and then
