sorry to ask , i have a question along the same line. there is a clicking sound coming from the top end. it gets faster as i rev the motor & isn't always constant. it probably does it about 50% of the tme. i've narrowed it down to the intake manifold side of the engine. i really haven't modified the engine that much. the car has 70k but the motor has 40k on it. could this be a rocker, or is it a valve? i'm going to take it to the acura dealer for a valve adjustment ($90 + $40 gasket), but i don't want them to tell me it's something it really isn't & waste a couple hundred. any help would be GREATLY apreciated.
thanks guys.
