Just bought my first RR Silver Spur and very nice it is too.
Got some kind of fuel problem that when it has done about 10 miles it starts misfiring, feels like fuel starvation and fuel pump gets noisey. It has stood around for a while - I suspect junk is getting on the coarse filter in the tank. Switch engine off for 10 secs and restart and its fine for another 10 miles. Its not tank vacuum, checked that - any other suggestions? What grade engine oil should it have (1989 Model)? Thanks.

Congrats on the Purchase. I cant help too much on the problem other to suggest using an engine cleaner, or perhaps the spark plugs/HD leads. Not sure if that is the right approach but hopefully someone more technically minded will be able to chip in.

Do post up pics when you get a chance.

If it's an injected model, those Bosch fuel pumps are known to start screaming when they get weak. However, as you say, if it's starved for fuel to move, that'll also make it noisy. I'd first start by changing the fuel filter and see if it improves. Coming from someone who was with Mercedes-Benz for 11 years, and who has seen an awful lot of these pumps in his day, try the FF first. If no joy, make sure you have good flow from the tank outlet. As an aside, you can do a pump volume test at the fuel distributor inlet--should deliver 1L/30sec.

Good luck! My '89 Turbo R is suffering from a whining fuel pump too, but (knock on wood), no running issues as of yet. I'll shortly get round to R&R'ing the pump and filter as a pair and that'll likely put that issue to bed.

Cheers,
Aaron

Hi, general area? I live in just south of Manchester.
The car has been stood a while and not done many miles in the last 14 years (around 5000).
I have a Daimler whose pump gets noisey in the summer only?
The Rolls had a pump and filter not that long ago, miles wise, but along time ago, time wise. When I switch the ignition off and restart, the problem is cured for another 15 minutes. Will try a fuel filter.
Is there a better pump?
Also got leaky steering rack - very common I hear.

Hi, OK made a bit of progress with my RR. Changed the oil, and anti freeze.Fixed the loose goor capping and sorted the central locking on that door too. Fixed No. plate lamps (one had wire from boot light and vice versa) so that would have never worked. Still got this noisey pump - have done quite a few miles in it now and it has only once now done the misfire thing, again switch off and back on and its cured. I see the pumps are 300l per hour. They do one for a Subaru that spec around £50 as opposed to £150 for the proper RR one. I am rapidly finding as soon as you say Rolls Royce, the price is times 4.
Motor factors wanted £29.50 for an oil filter - when I found a pH2995A did the job, it was £5.16.
Re - silvered the headlamp bowls too with sticky vinyl - wow, what a difference!
I can see, I can see!!
