I have set the timing on a GE but never on a GTE.now pertaining to the GTE do I unscrew the cam sensor cap? I have turned the crank shaft by hand with the battery disconected of corse.I matched up cam gears with the notches and crank shaft with the zero but when I unscrew the oil cap and look down the cam nose isn't looking straight up which I think it is suppose to,its been awhile.
