    Default 18RGEU valve timing help

    I know its probably here somewhere in here but cant find it,,
    I dont have a manual for this thing

    Im assuming its just both the cam notches straight up at No1 TDC.??.

    The 4 position cam gears.How many degrees between holes. Mine was on the 2nd hole from the left ..is that standard factory setting.??

    Also valve clearences as well please.



    Regards Dale

    For clearances:

    I may have to re-write what I previously wrote up about setting cam timing on the early twincams. Basically as a start, try to get the notches vertical at No. 1 Compression TDC. If you do that and find you are 180 out on the dizzy, you have your intake and exhaust cams mixed up... but this is not a problem as they have the same duration and lift from factory.
