    Default cam gear changes problem 4agte

    Hey guys i tried to put some bigport cams in my n/a lined it all up with TDC and cam pulley marking and replaced cams .. Now its all back together i havent touched the CAS as i didnt think you needed to , but after trying to crank it to start car wont fire up just only crank.. Question is how do i setup the CAS now with the crank and cam gears ????? as it was working 100% before i started Fvuking around with it.!

    if you changed exhaust cams.. then it would be very easy to bump the CAS gear when installing..

    what angle is it on timing light? (while bridging T? and E pins)

    You need to re-install the cas. Not point doing half a job.

    Consult the 4age guide. Its very similar.

    The guide doesnt show anything about the CAS. ive did everything to get me this far... crank pulley is set to TDC and with the cam pulleys aligned, with the timiing cover markings

    My understanding was that i needed to adjust the CAS to suit the crank and cam pulleys.

    pull the cas out, there's a line in the housing near the shaft, and a mark on the gear on the end. Line the mark on the gear up with the line in the housing, install to the head.
