Technical Engine dies in left turn PROBLEM FIXED

Discussion in 'The Hokey Ass Message Board' started by steel rebel, Apr 17, 2014.

  1. Had this problem on a customer car in the late fifties, confirmed it on test drive. Car would start right back up. After looking at all the usual things we had him leave the car. He had to take his the ignition key off his ring when I dropped him off, as he had all his work keys on the ring. When driving back to the shop the problem was gone. Found that the switch was worn probably due to all the weight of the keys, solution was a second ring with only the keys for the car. Some times the basic diagnostics don't work.

    Had it on an early Mark IV. Turned out to be carb related.
     
  3. Long time ago I had a similar problem on a friends car.....
    Pulled out all my hair trying to figure it out, turned out that he had the
    coil mounted sideways and the oil would slosh inside on a turn and somehow short out the coil windings, shutting off the engine.

    Thinking back to my first thought. The new fuel pump. Didn't have the problem before it was installed. Wondering if the extra pressure might be blowing past the floats and causing the carbs to overflow into the choke vacuum ports. just another thought.

    I have a lot now to think about and look at.

    Just the power of observation, that motor is not something that a Cad service bulletin from the 50's would cover and the op did not mention that this was a new build and out for the first test run, so with that in mind we can say that this turning problem just started with drastic results.

    Yeah check the ground, but also look at the motor mounts. I had this issue once but the real problem with the ground was the engine mount was broken and allowed the engine to rock and was actually pinching the ground. This only happened during right turns and hard acceleration.

    GROUND

    get a pair of jumper cables and hook to the block, and frame (metal to metal contact if possible) to a bold or something.

    Update.

    Spent some time on the car today. Not sure if this has anything to do with the original problem but when I tried to start it everything electrical went dead. Nothing. No lights nothing. Then it would come back. Then I would go away again. After spending a couple of hours looking for bad connections and grounds I decided to buy and install a new solenoid. It has a Ford solenoid before the one on the Cad. starter. Electrical seems back to normal. All works now. Didn't take it for a ride so don't know if the stalling problem has changed or not. Will update you when I drive test it.

    Think I have it fixed

    Replaced the 10+lb electric fuel pump with a smaller less pressure one. It now runs so much better. Doesn't die in the left turns now. I think the high pressure pump was just pushing past the floats and flooding.

    Thanks all for the input.

    Glad it's fixed!

    I sorta had that same problem with my VW type-3 after I hopped it up.

    I could never seem to lean it out enough, even after going way down on the jet sizes.

    The addition of a fuel pressure regulator solved that one.

    I've heard stories about Big Block Mopar Cop Cars that had this problem...
    Forgot if it was right or left...?

    The Gangsters would drive around in circles until the cops was left behind...

    Thanks again everyone.

    When your only tool is a jumper wire, every problem is electrical....

    You know it was both electrical and fuel. The first thing I changed was the solenoid and it ran a lot better. It didn't stall in a left turn but stumbled. After I installed the little clear/white "Made in Germany" fuel pump I bought (I can't remember where) it runs better than ever and and a lot is quieter.

    So you, we were all right.

    I hate it when their is two problems and one of them is intermittent.

    Fuck why do we do this shit.

    I hope that's sarcastic. Remember sarcasm doesn't usually go over too well in the printed word.

    Anyway a good reason to bump this one more time.

    Thanks again everybody. Yes even for the sarcasm.

  29. I'll betcha if you start out fast and make a hard left, it'll still do it. I had a 55 olds with one of those Rochester 4 jet carbs on it and when I'd hammer the throttle and crank the wheel left, the engine would almost stop running.
    Jon, "Carbking" here on the HAMB said it was a problem GM fixed with some kinda anti-slosh barrier they installed inside the float bowl.
    Glad you fixed yours.

    You know Rocky you might be right, although I don't remember having this problem in the thousands of miles I drove it before I installed the high pressure fuel pump. I only drove the car a few miles since I made the changes but in that short drive I did take off hard on every left (and right turn for that matter) I took, to the extent of breaking the rear tires loose. If in driving it in the future the problem comes back I will let everybody know in this thread and put "problem came back" in the title.
