Thread: rover v8 firing order ?

  1. #1

    Unhappy rover v8 firing order ?

    hi all ! is the firing order on a rover v8 the same on all years and are p6"s and sd1 "s the same order ? the rover v8 in my 100e ran o.k ! but then wasnt started for a few months and now runs crap as in lumpy and cuts out so i thought the leads were duff ! so i fitted new ones one by one as i took the old ones off but its still the same the plugs are o.k so could it be something electrical ???

    As far as i know both firing orders are the same 1-8-4-3-6-5-7-2 i think from memory
    Have you checked the dizzy cap for cracks etc.,or if your running points and condenser as condensers are crap now a days
    Could be coil breaking down,or if you've got su's are the dash pot levels ok?
    Have you got a spark at each plug?
    Or is the fuel getting through?
    That's about it for my limited knowledge

    Not all RV8's have the same firing order on the cap. Dont know if any difference between P6 and SD1 but the SD1 rover in my series hybrid is one plug further clockwise than my 3.9 Discovery. Inah it doesnt help the problem but just thought id share it anyway. Is your vaccum advance unit working as have a habit of rubber perishing if sat for a bit.

    that'll be the same firing order, but the distributer was one tooth out when it was fitted...

    start with the basics... got a spark at the coil, then at the plugs, then make sure it's actually got fuel, there's fuel at the carbs, floats not stuck, manual or electric pump working, and so on

    I found aftermarket rotor arms could be troublesome, worth a look.

    If it was a tooth out it wouldnt run properly.

    Hi Lee, i think the misunderstanding is that you can put the leads anywhere on the cap as long as they are in the right rotational firing order ,then you just rotate the body of the dizzy to #1 lead cylinder at TDC (or to the the recommended Btdc)
    or put simpler #1 can be anywhere ,as long as its timed in to the recommended BTDC

    Otis Redding couldn't set up an engine for **** 6-3-4-5-7-8-9 .

    The (correct) number for a Rover is the same as sbc and bbc and needs to be etched on the mind
