So the engine is still working fine, the only thing that ever happen was the belt coming off bending the fan, pump and cracking the timing chain cover. The transmission had been slipping some on hard acceleration, so last night I decided to change the fluid for the hell of it. To my surprise the pan was clean, the oil was old and in need of a change for sure though. I also drained the oil from the converter as there is a little drain plug for it, I installed a new filter but didn't bother using the new gasket that came with it. It looked to me that the old ford gasket with the steel insert was still a better gasket than this rubber only one - so I reused my old ford gasket and its working fine, no leaks. 15L of fluid later and the bronco was moving again, shifts were smoother and firmer, and I didn't feel any slipping this time.
That is not to say a rebuild isn't in my future, just bought some time I figure.
The other problem I have and I'm most certain its my IAC, though I've tested it and for all accounts seems to be working as it should. After the bronco has been running for a while, when i go to restart it, it surges and dies, have to feather the throttle to keep it running, doing this for 30 seconds and its idling just fine again. So I'm thinking maybe the IAC is sticking some, though I had it off and cleaned it and the plunger moved with no effort. So I have some doubt that it is indeed the IAC and not wanting to piss 100.00 bucks away on something that may make no difference I need to do a little more digging. Worse thing is I should have a couple spares but I either gave them a way or chucked them out.
