So while i was messing with the '90, the engine in the '96 started squeaking.
So bizarre. Im not going to waste your time with the troubleshooting, but it wasnt the accessory drive.
Long story short, the distributor bearing was bad, and the shaft was rubbing against the housing and squeaking. You can see what looks like iron dust inside the distributor in the above pics. New distributor ordered, and installed:
It got a full tuneup while i was there. This time i bought Blue Streak 9mm wires, which include their own wire retainers, and boot sleeves if you have headers which is kind of cool
They have a ton more insulation on them than Ford Racing 9mm Wires. Beefy!
So that takes care of the '96, lets get back to the '90...
