[QUOTE="urbex, post: 762490, member: 15915"] It was immediately obvious that I had a problem right from the get go on that one..had an insane amount of steering power right at idle, but lost _all_ power assist after about 1200rpm. It was like the pump didn't even exist. Back to idle, and it worked again. But it took about 30 seconds before the fluid started boiling out of the reservoir. Didn't even make it out of the garage on that pump. But it never whined or anything like that that you would expect a pump stuck on bypass would be doing, so it didn't immediately click in my head what was going on with it. Replaced the pump, took the plug out of the PB port, and tee'd in with the tank return line, seems to work fine. Never any hint of lack of power, locking up, or anything weird like that. Even at speed when the front end is jumping around, I never lose steering, I just can't get it to go straight again until I slow back down. Kind of like bad death wobble - doesn't settle down until you slow down too. That said, if I can conclusively point to the valve as being a problem now, I don't have a problem replacing it. I'd rather just buy a new one, rather than take a chance on buying someone else's problem child too. Though I'd probably crack this one open first to see if there's any evidence of burnt seals or similar. Char-Lynn 291-5012-001 [/QUOTE]
