Hey guys, i need help...

Just changed a head gasket and was wondering if when the marks on the crank and cam sproket line up, should the rotor on the dizzy line up with the start mark on the dizzy?? Its sitting about 10deg before the start mark. Car is 3.9L duel point injection

The dizzy is not essential at this point.

The way I usually do it is to get the motor together, THEN put the dizzy in - as long as the motor is at TDC on the firing stroke for no.1 cylinder, whichever lead the rotor points to is for no.1 plug lead. It's just a matter of reinserting the dizzy with the rotor set up in such a way as allows the plug leads to stretch over the motor.

Yes 10 degrees before cyl 1 is about right.

I don't know if I am reading your post right, mongrelEB, but if you are saying that you can just set the engine up on TDC for cylinder 1 and drop the dizzy in any way you want, and whatever cylinder the rotor is pointing at, make that number one. That used to be fine on older engines, but the ford eec needs the leads to be in the correct place.

Thanks boys..

that way will work, but it's not the best way at all to do it. All it does is create anger in the person that gets caught out by it next time.

Another things, with those early ones, they had the black plastic cover that goes on before the rotor. That had the start and finish marks on it to get it lined up correctly...
