1990 Turbo R Hydraulic leak Question
Discussion
I am looking at a 1990 Bentley Turbo R in Toronto. 72,000 mile car grey marketed into Canada from the US. I don't know too much about it - and nobody knows any real details on the car as in where it came from / has it been abused (it is a friend of a friend of a friend kind of a thing).
It has later model 18" wheels, and needs new rubber as 1 of the tires is chewed up.
Here is the real question. The hydraulic pump is leaking fluid from the top. When the car sits it looses fluid and pressure, and when re-started the Low hydraulic / brake light comes on for about 3 minutes (obviously until it builds up pressure again). When the car sits for a while the back end sits low presumably due to the same issue.
The car is cheap if these things can easily be remedied.
Is there some relatively easy way to tell what is causing the leak and if it can be repaired?
I would appreciate your responses.

It could be anything Jim, from just seals or unions, to failed accumulators, or the pump. A dealer or specialist would know what to look for, anyone unfamiliar with the car though, may well struggle to make a diagnosis or pinpoint the problem.
Hard to say on the web, unless you can post some pics of where it appears to be leaking from.
If it is overfilled, and the car then sits, it leaks out of an overflow near the mineral fluid tank, and comes out on the floor under the car near the left hand side 'A' panel. They also sit on their arse like an old Citroen if left for a few weeks without being run.

there's two different styles of pump - one can be repaired whilst the other cannot.
make sure its the pump, they are difficult to see and not evident at first glance - there are two, one driven from each end of the camshaft and situated vertically under the inlet manifold.
They're actually based on sections of diesel injection pumps - the top seal is an "O"-ring, but on one design, the top doesn't come off.
if the car is in Canada, there's a "local" breaker - google "crewecutters"
failing that, try Flying Spares here in the UK. just don't expect a new pump to be cheap.
for further information, you can download the workshop manual, it's available on the Rolls-Royce Club of Australia website
hope this helps.
p.s. I'd seriously recomment throrughly cleaning the reservors and replacing the four pressure reservoirs whilst you're at it.
