dumb question, but how do i identify the s13 cams, which is the intake, which is the exhaust?

DiDDY

 

Green is Intake, Orange is Exhaust.

 

the ones i have, have neither. one has a 1 and the other has a 3.

 

I kinda have same question as diddy.

Does nissan use any identifin marks or numbers on the actual cam to designate them?

I am in process of replacing seals in the head and had to pull my cams which i got two years ago and I ordered 2 91 ka exhaust cams. I want to be sure I got what I paid for.

My cams have a number 4 just about halfway on the cam stem (in between the cam lobes) and also 53 degrees or 53F. Do these numbers mean ne thing. One of the cams has orange stripe the other has green stripe.

 

The orange one is exhaust, the green is intake, I have no idea about the numbers...every cam I've seen for the KA has always had the paint.

 

mine have a 1 and 3. uncertain of the degrees since the gears are still on.

 

Thats not always true. the best way to check for intake and exhaust is on the intake the first lobe lines up with the dow pin like this pic.
