    Question S3 died on the way home

    I took my Series 3 109 for a Sunday drive this afternoon. It was a fairly bumpy ride and everything got well shaken around. At one point on the track, 1st gear 4WD engaged, I had a sudden loss of power and had to pull up, whereupon the 6cylinder stalled. This didn't surprise me too much as I've just repaired a badly leaking exhaust manifold joint and it's been a bit prone to stalling since then (but that's another story). Got it started again but she ran badly and backfired a few times before settling down to running normally. I completed the rough part of the track okay and got back onto the Bells Line of Road to drive home when suddenly no power, pull over to the side of the road and she stalls and doesn't want to start.
    Reseated the plug and dizzy leads, checked the coil wasn't overheating, checked fuel was coming out of the carbi side of the fuel filter. Can't find anything wrong.
    I could get the engine started with plenty of choke but she blows white smoke unless I give her lots of choke. Then after a few minutes she dies or if I put the choke in she dies.
    It was getting dark and starting to rain so I left her beside the road and rang for a lift home.
    Any advice on what to look for would be appreciated as I'll be going out there tomorrow to work on it.

    Thanks for the suggestion I didn't check that.
    However the problem disappeared and I got another kilometre down the road before it all happened again so I wouldn't have thought it was an adjustment gone wrong?

    Hi Disco Dave

    Some thoughts on your subject

    I would:
    1: Take another coil out with you
    2: Check the advance mechanism inside the Dizzy & check the vacum advance (suck on tube)
    3: Don't know if you are running a resisted coil block / so feed 12v (hot wire the coil)
    4: take a spare set of leads / plugs & Dizzy cap
    5: Dizzy cap could have a hair line crack / replace
    6: Compression test

    7: WORST CASE.... is the motor is old? / I don't know if the cam is cog & chain driven / if so then the timing chain is too loose and it has moved a tooth / take off rocker cover & rock piston over TDC and watch for the position of tappet trick ( piston 6 going exhaust to Inlet)

    Can't think of anything else, other than worst case of (white smoke) blown head gasket

    Hopefully it will just be something silly

    And what about the little silver capacitor connected to the coil or the points
    Sometimes they short out / just disconnect it / as they only help your points from burning

    Also the bumps can dislodge the earth wire inside the dizzy (That exposed braided one)

    Just a thought how about the fuel fiter? all that bouncing around could have stirred up a pile of muck and partially blocked it.

    Changing the rotor might be worth a try too - years ago a mate & I were coming home from a trip in his 6cyl S3 and it died - we left it there & returned a couple of times to try to fix it before we finally replaced the rotor - presto! Problem solved....

    Original Landy 6????
    If so I will almost bet my left nut the dashpot in the carby needs topping up with oil.
    Mine used to behave exactly the same way.
    Misbehaves firstly on hills then on the flat too.
