Hope its not bad form to have two topics up.
Ok to explain this in short. I put this distributor in several years ago and only ran the car a dozen or so times. It ran good but the intake leaked and carb was under powering the engine so i changed it last week. It has not truly ran since...at least not right. So after playing around with the timing and pulling the dist. twice to make sure it was not a tooth off i pulled the rotor out of it. If you know these distributors they have a square peg and a round peg that are supposed to make it so the person assembling the thing can only put it on one way. Well mine proves you truly can put a square peg in a round hole. The rotor was backwards in there for this whole time...
So now what? Since the rotor was 180 out does that mean where we thought tdc was is actually 180 out in the block? how could this thing have ran for over a year with that in there that way? The only way that makes sense to me is that the motor is out 180?
Also i found some pictures of these in cars and the wire coming out of the bottom of the dist. body is straight forward. Mine in my car, where it is supposed to be timed correctly timed at 16btdc, is over top of the water neck on the intake? This is how it has always been, even after we put the rotor in the right way, pulled the dist. and repositioned it as it should be to tdc #1. Still a tooth off and 180 out???

Thanks allot. This is more than my mind can handle. lol

The distributor was 180° out the whole time. Pull it out, and turn it around.

It doesnt matter where #1 is on the dist. Just as long as the rotor points to a tower when #1 is at TDC and the wires are in the correct firing order it will be fine. The only time it matters is EFI where the PCM controls the timing and injectors.

Click to expand...

Even that doesn't matter if the cam sensor is indexed properly at TDC.

Still, everything is easier if the rotor points toward the master cylinder at TDC on the firing stroke of #1.

Ill get a picture of mine with the wire over the water neck tomorrow. I really hope someone has one and can let me see a pic of how its positioned in their car.
I have no idea why this thing is out of position...
