Starting this here since I can't replicate the issue in normal street driving. I replaced the PS pump, high pressure line, and fluid in my '95 5.0 this winter. I haven't had any leaks for a few months in normal street driving until I went to the track for the first time this year. So, yesterday my track day was cut short after I realized I was splashing PS fluid all over the place after my first 25 minute track session. My initial thought is the fluid is getting hot and boiling out the top of the filler. The cap is fairly loose. After sitting for about an hour the fluid got low enough in the filler neck I could start seeing the bottom "grate" thing at the end of the neck. So I topped it off past the grate (plus a little extra since it was still hot enough that the fluid should be elevated due to heat), let the car sit over lunch, and went back out for my next session. I did 3 laps (so about 6 minutes), pulled in to check on things and I had fluid all over the place again. I let the car cool for a while and fluid level seemed to only drop a little bit, if at all, this time. I pulled it up on the trailer ramps so I could get under and check things out. There was fluid just about everywhere, both ends of the high pressure line seem to be dry (as far as leaks are concerned), buy I couldn't really check the low pressure side with the tools I had. It simply looks like it's just boiling over. Anyone experience this before? What's the fix? I can only seem to replicate it on the track, and I really don't want to shell out $310 to go to the track for a few laps to see if my PS fluid is going to overflow again.
