Ok so i removed the two cams from a spare Z18XE head i had and didn't take note which was removed from where. I now have no idea which is the inlet and which is the exhasut cam.
I've looked on EPC and the parts are listed as:
Inlet - 9158623
Exhaust - 9158629
I've had the cams in the parts washer so i culd check for any markings on them, but they are labelled up identically - 76 83 R90 400 230
Can anyone shed any light please?
