Mixed up cams? aftermarket no markings
 

will a car run if you mix up and intake and exhaust cams? i have aftermarket crespos in my zc and someone has written "I" on the inside of the exhaust camshaft sproket. this makes me wonder if this was my idle problem. but i cant see how the car would run at all? should i put it back together as i took it apart? Is there a way to tell the difference between intake and exhaust cams that arnt marked?:o

please
 

Realy need to put this back together, noone knows how to look at the cams and maby see which one opens the intake on cyl 1 first? or somthing?

...
 

if i hold them straight up, (arrow pointing up) and imagine they spin counter-clockwise, the intake valves will open first right?

Both cams are identical as far as distributor side goes, obd0 with cam pos sensor.

they kind of only go in one way from what i remember. if you're eyein it up, don't forget the old "intake, squish, boom, exhaust" thing.

i would spend some time cranking it over by hand after you have it assembled to make sure that everything is lined up close to right and then just make small adjustments to get it perfect. or close enough...

sound like a mess

it is, i bought it for the parts the whole cars being dericed as we speak.

i would do what he stated that all the help i can be

we poped a friends valve cover and matched it up it was correct. some fucker was trying to ---- with me wrighting a I on the exhaust cam.

Sorry about that, we thought it was pretty funny at the time.

i think its hilarious if it was intentional. and just dumb if it wasnt.
