ok I know how to remove and install one, but how accurate does it have to be?? I mean if your timing is off between the crank and cam that can't be good. This is the last main thing keeping me from actually starting the baby... (also the fact that I got all excited and put all the parts back together and now realized I can't get to the tamperproof torx bolt - thanks supercharger) and I don't feel like taking the wiring harness plugs etc all back apart to get to the bolt (any suggestions?) but the main question is I am assuming that if the CAM sensor is off even a few degrees it could cause engine damage. So how do you adjust the sensor back to exactlly where it needs to be??? I doubt even ford would know exactlly how to because they are set from factory and there is a "caution - non adjustable" on the top. Grrrr... when will this madness end?
