Holy smokes.
I've replaced the battery, fuel regulator, and lower aos vent hose.

Pro tip on that hose:
It can be done with the intake distributors attached, but the oil fill tube, alternator, rubber plenums, throttle body, air box, and a starter cable needed to be removed. Take specific note of how the old one routed, as there's not really a good diagram online to tell you how it should go. And most importantly; If you've got a spare cash, please just let an Indy do it. Ye-ouch!

Anywho, the in-between oil fill tube (99610725403) has been replaced by some previous owner with an aluminum dryer duct hose. It's leaking oil and probably the source of a major vacuum leak. Previous owner was nuts apparently…

Also, is the spring drive belt tensioner (99710226000) replaceable in an easy manner? My belt wobbles around an inch when running, and I think that old spring just isn't putting out pressure like it used to. I can pretty easily press it in to get the belt off, but it doesn't spring back at all. I actually have to push it back the other way to tighten the belt again.

Thanks.
