went to start had a little trouble with timing, but got it running good, but I have a sort of loud deep knock at idle like a rod bearing double knock and is intermittent, did not have be fore, I thought it was the water pump because of the extra pressure on v belt with AC, so I disconnected the belt and noise is still there. what could I have done?
