Firm hose could mean being pumped up with some steam. Air locks and blocked radiator are the duel causes. Both issues are addressed here for the Rover SD1 V8. Rover SD1 Tips 'n Tricks - #2 - V8 Coolant Fill without Airlocks Try applying the solutions to your arrangement. If these are...

Hello Paul, I believe the viscous unit referred to is similar to the item fitted to earlier Rover SD1 Efi cars. In my experience the most common of two fail conditions is when the fan does not speed up due to insufficient bond between the wheel and the housing resulting in overheating...

Hello Ian, do yourself a real favour. Irrespective of the vehicle you drive the answer is always, exactly 58 mph. Whatever you do with the loud pedal you simply cannot do anything about the awful coefficient of drag generated by your chelsea tractor. So - get into lane 1 of the motoway and...

Some things your garage might have missed - condensation inside distributor cap, coil suppressor capacitor breaking down, earth connection between engine and body corroded, ign amp playing up, try to get it to happen at night with no moon and when it does open the bonnet to see if...

Hello Uncle, Your RR will be similar in performance to my SD1 so the article I wrote about SD1 exhaust system "choice" may be of interest to you. The bottom line is that a (SS) sports exhaust system does not generate more horsepower but it may mitigate some of the losses caused by a more...

Industrial spiral wound, double skinned hose of various diameters is available from Ducting Engineering trade suppliers. I made these in 1994 and they are still perfect. I got the hose I wanted as a free sample from the wholesaler, "Rapduct" in Wolverhampton, UK. To overcome any minor...

Hello Stefan, For the purpose you describe the trickle charger would be fine, except that the battery still has to be in reasonable condition to accept the charge. If the battery is dying then you can assume it will shortly be dead. Then you are going nowhere. If you are determined to keep...

Thanks to Paul and Sirus, for changing my user name so effortlessly, :), Cheers! Ramon

Hello Red, I have some other inputs from several quarters who say it was an icing thing and one from a club member who said his had been bypassed for ages and he had not noticed any difference in cold weather. I turns out that it had been bypassed since he owned the car and he was...

Hello Red, As far as I know, this feature first appeared on the Rover SD1 Efi Vitesse in 1982 and was subsequently on all Efi SD1's until production ceased in 1986. thereafter it appears on many if not all Efi Rover V8's This is my personal theory supported by a scientific explanation...

If the fault simply cannot be traced you might consider running in another feed from the appropriate fuse or from a live battery source with an inline fuse adjacent to the lighter.

Yup! Maybe some of the other stuff on my site may help track it down.

Hello Ozzy, Could be the non-return valve in the Plenum to Brake Servo pipe has jammed or the servo is breached and wont hold a vacuum. With this wide open then it is a serious plenum air leak and will create fuelling/mixture problems. Otherwise there is another serious air leak into the...

I'm assuming you have a 3.5 Efi Flapper system. The signal that tells the ECU the engine is running is also used to drive the tacho. If the signal source (coil negative) connectors or wiring is dodgy this could be the reason. Check the integrity of all the wiring and any relays in the...

I'm new here and am familiar with the flapper system as fitted to the Rover SD1 Efi cars. If your system is similar, then from your description including wet spark plugs and refusing to fire, it sounds like gross overfuelling. Two main causes can be: * Cold start system remains on after...
