Hi!

I have XK8 '97 in the garage with minor problem with the power steering.

Every now and then (specially after heavy accelleration) power steering pump gets noisy (burr?) and steering feels sticky. When I stop the car to the side of the road and turn the steering 100% right or left (or both), the noise stops and steering works normally (until the next time).

Now here's the funny part. Pump have been changed two years and 3000km ago (new pump in Jaguar service) and there's no fluid leaks at all. I checked also the oil reservoir and there are no bubbles etc which could refer to air leak in the system.

I was wondering if there is some kind of inner leaking in the steering rack? I also read from some different forum that someone had problem with oil reservoir's filter which was blocked and pump didn't got oil enough? What do you think could it be possible?

Only thing I have noticed is the (no pressure) return hose has some moisture outside the pipe. I took the car to jaguar service, but the steering was working just fine that time, so they couldn't find any problems with the steering when having a quick look.


Thanks in advance, appreciate your help.
