im setting up the cam timing with my new engine to check for piston to valve clearance.
heres my cam specs
i set up the cam timing as per factory specs.(cam lobes at 10 and 2 o'clock bright link on mark on the crank sprocket, bright link on pos 1 on cam sproket and cam dowel in pos 1 cam sproket and v notch on the mark)
with a degree wheel on the crank and tdc found and marked, i checked the cam timing from the cam specs on this card.
everything lines up well. i get inlet and exhaust opening at the same points on my degree wheel as the cam card. both the .017 and .050 valve lift readings are the same( inlet opens 44 @ .017 & 28 @ .050, exhaust opens 82 @ .017 & 66 @ .017)
and im also reading the right valve lift .595 lift
but the cam specs say inlet close at 66 afterbdc @ .050 and im getting 54@ .050 abdc
and on exhaust specs say ex close at 28 atdc @ .050 and im getting 16 @ .050 atdc
when the specs say i should have .050 lift on the inlet and exhaust closes, i checked what lift i have at those degrees(inlet 66 abdc and exhaust 28 atdc) and i actually have .017 lift.
and when the specs say i should have .017 lift on the inlet and exhaust closes, i checked what lift i have at those degrees( inlet82 abdc and exhaust 44 atdc) and i actually have 0 lift the valves seat at exactly those degrees.
anyone know wtf is going on here??
