If my crank and cam timing is off by a few millimeters, would that make a big difference?Because I could align the crank to TDC, and the dash marks on the cams is like a hair off.Car runs good,seems perfect, but wen vtec opens, its really loud,its not a rumbling vtec sound,but more high pitched,i was affraid it could be the engine pinging,but when the car is cold,it goes thru the revs,once it warms up vtec cracks but its just loud...any opinions thanks..and its an H22a motor.
