My new to me '67 Coronet with a '77 440 is doing something weird (to me anyway, maybe it's common). After awhile driving, it starts pushing all the power steering fluid out of the pump reservoir fill hole. Appears as if it's boiling it, as it's very hot and frothy and literally boils out. The steering box is pretty worn, on the to do list is to adjust the screw on the top as it's pretty loose (I know its a band aid and I'll eventually replace it) and the valve at the top needs to be adjusted as it turns itself to the right. Is the pump shot or is it continually being worked by the out of adjustment steering chuck?

Yes it's being worked by the out of adjustment box.

Thx for the reply guys, I figured that had something to do with it. Any good info/links on how to properly adjust it? The Factory Service Manual has the procedure if you can get one (good idea anyhow, MoparManuals.com). Its been posted a few times but I've never done one. Basically you slightly loosen the block and tap it left/ right with wheels in the air and engine running until you find the point it stays centered and tighten it down. A power steering cooler would help keep things cool and prevent boiling also... but need to get the box healthy first.

OK but with the assist valve out of adjustment, the pump is constantly trying to build pressure. Building pressure builds heat.
With the assist valve centered, the pump merely circutales fluid and stays cool.
