Power Steering failure

[Glen]

My power steering reservoir has always been weepy as well.
Dealer reduced the volume of fluid, seemed to solve the issue.

The same power steering reservoir used on the Grenadier is on my ‘94 Porsche 968 (BMW & Porsche used the same supplier). For the first 30 years, no weeping, even with the original o-ring. And the low pressure return of the 968 can dump a huge amount of fluid all at once. So if the reservoir is weeping a lot, I’d be looking for a warped cap, a poor-fitting o-ring or flashing on the glass-filled nylon parts.

I put Agile Offroad’s larger o-ring on my Grenadier’s PS cap as a preventative measure for angled terrain - it still doesn’t weep.

edit: What happened after the first 30 years? I replaced the PS reservoir (when I replaced the hose) with the latest Porsche / BMW part because it has a barb molded on the integral plastic low pressure return fitting, unlike the 1994 version. No weeping on the new reservoir either.

Did the same. Mine still weeps. Gave it a little more muscle so we'll see.

An old dirt track trick - the engine breathers on top of valve covers would sometimes fog from excess engine vapors. Low tension piston rings and high RPMs tend to contribute. The solution to not getting oil everywhere? Cut up an old tube sock and wrap it around the offending breather. It would have to be changed/cleaned occasionally, but the “oil on everything” issue was solved.

Just a thought.

I figure it could have been an overfill by the selling dealer. I purchased used from a BMW dealer, they probably don't service many hydraulic units nowadays. I will let it bleed down a while, keeping an eye on the level. then I can determine if the condition stops.

I had an old Jaguar once. Sometimes when hitting a bump, the headlights would go out…

We had a BL Series II XJ6. Same exact thing. Riding around Oxfordshire with no lights became a running joke with us and the local police. Of course, BL could NEVER figure it out.

We are now five weeks without the car. Firstly, like you, they could not replicate the fault in the workshop. But when i said, OK, I'll bring it back to you when I have an accident due to failed steering, they took a slightly different tack. Firstly they diagnosed a faulty earth on the pump, caused by overspraying. That fixed they then reported in week three that there were additional faults found on the pump and despite emails and calls with the UK Technical representative and the Spanish dealer nothing more.
I did get a call from the dealership sales manager on Friday offering me a new Black Edition for my car plus €46K!

The saga continues.

you made any progress with this?
