I got the gearbox oil leak fixed - it was the electronic speed sensor was bunged and not properly plugged - leaked out dripped on drive shaft and the rotation puts oil everywhere. - So simple yet so long to find the problem.
Tomorrow the car goes into another EFI workshop to see if they can read the chips in my chipped ECU and get the basics in shape before letting the ECU do it's job. Real pain as I finally found a crowd that did have the EFi / ECU tools but when plugged in they could not read the ECU chips -back to square one.
If it don't work in the next couple of days I'm going for the Webber500 carb set up - at least that can be "fixed" by most garages!
It could be worth your while visiting
V8 Owners Forum as they have loads of Rover V8 Gurus there - search function also works fairly well
cheers
