Question on a HEI dist, nuttered 4.2

This motor is Nuttered, I just figured this out by reading the nutter sticky, and tracing wires

I still have no start, and it sound out of time while cranking. I just pulled the cap and rotor to find oil under the dist cap, and rotor. Did a seal fail?
I get very weak spark. And it looks like the rotor hits right on the edge, and I have streaking.

I am heading to town now to pick up a new cap and rotor.

This motor ran perfect until 2 days ago. It died after idle.

If you have an HEI distributor then it's not really "nuttered" What you have is a self contained ignition system and anything to do with the old computer and any of the old ignition is just dead weight.

You should not have oil under the cap and since you do it would seem that a seal, a bushing or probably both have failed; sure looks like the shaft is loose from that rubbing.

Did you get the distro from CRT? They usually use red caps.

Warranty? If it's too late for that you can get a rebuild kit. Or, start over with a whole new one.

I was guessing Nuttered, thanks for the clarification.
I don't know where it came from. The PO did all this work. My father in law told me to try the module in the distro. And to make sure i am getting 12 volts. I'll give that a try.

It does say CRT on the cap.

This guy: http://www.crtperformance.com/

He sells a decent product; I have bought a couple of them. But, he seems hard to get hold of sometimes.

I would see if he will cover it, or maybe discount one. Maybe he would see just the base, since you probably don't need the cap or coil. Either way, I would just get a whole new one.

You could junkyard a GM distributor and swap over the bottom gear but you may have similar issues if it's old.
