  1. Fuel Injector connector fix (1992 Classic 3.9L)

    Range Rover Classic
    Thank you to everyone for all the great posts. This is my first (set of two) posts to offer a solution to a couple things I wasn't able to find. I replaced a fuel injector connector in my 1992 Classic (3.9L) with a generic Napa part. Between the computer and your fuel injectors, there are...
  2. 1992 Classic 3.9L V8 Runs Poorly When Hot

    Range Rover Classic
    1992 Classic 3.9L V8 starts when cold, runs smooth for approx. 15 minutes until hot then starts to run ruff until it finally stalls. Will barely restart. No power at all. When placed into gear, really barely runs. Exhaust really smells. No Check Engine Lite, no codes. New distributor, fuel pump...
  3. '89 RRC 3.9L V8 Crossed injector wires

    Range Rover Classic
    I bought this 1989 RRC May 2015 for $4,000 knowing it was a fixer. It ran crappy so I attacked sensors and did the needed tests. These things help however it still has this nasty hesitation from a stop or even stomping the accelerator from a cruise. One day when cleaning the breather mesh I...

    Range Rover Classic
    Hello, I've been wanting more power and or improved MPG out of my 94' 3.9l RRC. After doing some reading, I stumbled upon Tornado and Optimax ECU Chips. I don't know much other than what the company claims it can do. Has anyone re-chipped their Classics? Is re-chipping something I...
  6. Value of a 3.5L (pre-89) vs 3.9L US-spec Classic

    Range Rover Classic
    Long time no post, I've been lurking here a couple months since I'm about to scratch the RRC itch I've had for the last 10 years or so! I'm in the US btw if it makes anydifference. I'll try and not turn this into a "how much is it worth" thread by not using any numbers. I really want to...

    Range Rover Classic
    Just did the 4.6L conversion into my 94 range rover classic, primed oil pump with impact drill intially had 20 PSI then dropped to 10 PSI at the same consistant speed.

  8. need to find local machine shop w/ 3.9l sleeve install experience

    Range Rover Classic
    need to find local machine shop w/ 3.9l sleeve install experience Wondering if the community has any contacts in the DC/VA/MD area that has experience rebuilding 3.9/4.2/4.6 with flanged/tophat sleeves. I'm hoping to spend less than 5k, as it's hard for me to justify spending that much or more...

  10. Oil pump priming problem on fresh un-started rebuild 3.9l

    Range Rover Classic
    Evening everyone, I am getting ready to start my fresh rebuilt 3.9 for the first time and am having trouble getting the oil pump to prime. I packed it with petroleum jelly during install and filled the NAPA filter with SAE 30 VR1 oil. I had a friend watch the dummy light while I hit the pump...
