Re: 1984 Ford 2.3L powered Bronco II

The body lift had an expected benefit. The header for a car application I had hanging on the shop wall now clears the evaporator plenum. Installed it and welded up some 2.5" pipe. https://fordsix.com/img/upload/2018/09/02/20180902103201-7b47d8e7.jpg https://fordsix.com/img/upload/2018/09/02/201...

Re: Fluid leaking from E40D

Most likely the front pump bushing galled, stuck to the torque converter and then spun in the pump housing. It's an E4OD thing. Usually happens under load.

If so, it will need a front pump, and possibly a torque converter. A new/reman pump will have the bushing staked so it can't spin.

Does the pump whine? Ford pumps use six vanes vs a Saginaw that uses eight. Lose one or two from wear and the pump output drops, along with a noticeable whine.

Check the pressure relief valve under the high pressure line fitting on the pump. It may be bleeding off pressure at idle.
