Well, I was able to get all three oil passages tapped and plugged with the engine still in the car. It turned out perfectly, and now have 60 psi of oil pressure at around 1400 rpm on the distributor. Turned out better than I hoped.

I got everything back together today, and even swapped out my brand new rack assembly that leaked new out of the box. Now, the only issue.... no spark. I checked everything 3 times, and its all connected perfectly. I hooked my timing light up, and no spark with it connected. Swapped the coil, same thing. My MSD has its light on like it should. I am thinking that my ignition module went south. I got the distributor used from a friend with this module on it, so I have no idea of its history. I do know that it looks very old. As I crank the engine over, randomly I'll get some sound of ignition on the intake side (like a pop inside of the intake), but very rarely. No matter what, I get no light on my timing light as I crank, so no spark to the wires.

I pulled the distributor to pull the front of the engine apart, but other than that, I haven't done anything that would cause the module to go south. I have good fuel pressure, voltage at the coil, and no spark at all.

Anyone have a module just go south out of the blue, or do they typically act up intermittently? It was running pretty rough when it last ran, so maybe it was acting up then as well.
