There is a diesel saloon on offer with a leak (rear offside). When the reservoir is topped up it runs out in 6-7 hours. Does this sound like a high- or a low-pressure problem?

Impossible to speculate. Could be:

Metal hydraulic pipe.
Return pipe chaffed through or split.
Return Y piece perished.
Suspension cylinder boot.
Sphere seal.
*Possibly* suspension cylinder, but they usually go in a rather more spectacular manner!

I'd consider worst case scenario to be burst metal pipe and the rest of the pipework being U/S too, necessitating complete (or at least back end) repipe.

Not hard, but time consuming and fiddly.

As he says BUT if its a HP leak surely it would empty itself in alot quicker than that?

Thanks chaps.

We shall never know the answer, because the vendor did not realise that the term "rust" could be applied to corrosion not visible from outside the car, and had therefore not thought the holes in the boot floor worth mentioning. C'est la vie!

Depends how bad the leak is

Roughbert, that grey TZD Turbo on ebay looks well worth a punt!
