Full Version Where Is The Pressure Going?

Hi all

I have an ongoing although not to serious loss of hydraulic pressure which manifests itself mainly in cold weather in a very slow pressure rise from starting. Once up and running its OK except that the back drops very quickly and you loose all brake pressure after a few minutes. Noz suggested I disconnect the return pipes one at a time to see where the fluid is coming from, which today I did. I didn't have to look far as the large pipe next to the pump feed is returning large quantities of fluid even before the regulator cuts in, when it does the quantity changes from large to torrential.

I have tried to follow the pipe but it splits in two directly below the reservoir, one goes to the front, which I suspect is the regulator return and the other heads for the drivers side, changes into a metal pipe, and then dissapears. Any suggestions?

According to Peter Russek, that particular connection is the return from the flow distributor and the steering control valve. If that is so then I wish you luck!

Hi Peter, just saw your response to my other thread...

So FDV then ? Oh joy biggrin.gif

I'll try and check the fluid return on mine over the weekend and report back, but it sounds very similar to your problem.....

As I say, it still drives OK. I fitted a new steering rack to my previous car, marginally easier than changing the head gasket but I would rather not do it again! sad.gif
