What would cause my power steering fluid to boil over?
I had my steering pump, valve and ram rebuilt recently (when I had the engine out of the car...), replaced all the hoses and fluid.
A couple of times since I got the car running again, after long periods of high speed idling, it looks like the pump has shot boiling hot steering fluid out of the filler hole. I have not witnessed the purge but the placement of the oil makes me think it's coming out the top (its on the valve cover, headers, back of the pump, etc). The fluid level is correct and I have cycled the steering side to side to purge any air but the fluid still gets super hot.
Later in the day - after the most recent fluid purge and cleanup, I started the car up to put it in the garage and it left a regular drip trail in the driveway as if the high pressure hose was leaking at the connection near the bottom (there was no fluid up high, only on the hoses). I cleaned up everything and wrapped rags around the lower hoses and over the filler cap. I drove it around the block (after it was cool) and there was no oil on any of the rags.
In the past, when the wheels were off the ground and turned a little, if I started the car and the wheels would turn to full lock. Not always in one direction. They go in whatever direction the wheels are turned at the time.
Does anybody have any ideas or suggestions?
