How the hell do you tell the difference which is an inlet and which is an exhaust cam??
i have 2 sets of Z18XE Camshafts all of which look exactly the same, im trying to work out the pairs so i can send off to be reprofilied!
3 of them have Big 'I's on but one doesnt, but then within them 3 that have 'I's on 2 of them are exactly the same but one has different markings on!
Are the inlet and exhaust cams exactly the same so im worrying about nothing?? or are they different?
