So, i made some progress on the 90 bronco.
Stripped the motor down and changed the timing chain
The smog pump is shot along with all the air pipes, so its all going away
Its not easy to see, but they bolt to the back of the head
The holes are threaded, because when flipped to the other side of the motor a threaded insert goes in it, and the accessory drive bolts to it. Which means we can plug the hole simply by putting a short bolt in it.
No smog pump means no TAD or TAB, so the vacuum system came off for repairs and the removal of about half the vacuum lines
pulled the plenum
and then pulled the fuel rail so i could clean and then rebuild the fuel injectors
i changed the rusty (but otherwise apparently in good shape) spark plugs
The IAT was super gross so that got changed, along with the ECT since i was already in there
So in the process of the rebuild, i decided to get rid of the fire hazard that is the 2g alt
Just a small amount of grinding on this web, and the 3g alt fits right in there
bracket cleaned up & installed; reman alt installed as well:
I also tossed the junk Ford steering pump in favor of a Saginaw off an Econoline
bracket all cleaned up, with reman pump installed
and i deleted the OEM cooling loop on the frame rail in favor of a proper steering cooler off of a Superduty:
