Unhappy

Well my recent posts have asked about my carb problems, but I have a feeling that the problems just got worse. I got the carb acting right not perfect but good enough to drive it to have a pro work on. Here is the new problem, while leaning into the engine bay adjusting the carb with the car runing I noticed that one of my header pipes was not hot at all and it was running long enough to heat up. After my initial response of screaming NOOOOO !!!!! I took a step back and started thinking about what just happened. I came up with one of two things, one, something is wrong with the head or I lost a cylinder what do you guys think it is. There are no unusual noises,smells,smoke or leaks.

Well lets see here... My guess without being there to check and with no more info would bet that you have a dead cylinder. Which means basically you could have ignition problems, valve/head problems etc. Could be flat cam lobe. I would suggest ripping the whole motor down to find the problem. Start simple like the intake and lifters/cam then go to the harder stuff like the heads etc. If its not making a huge knocking noise than you can bet it isnt a rocker arm. Doesnt sound like a simple fix if thats what you were looking for. sorry. Good Luck

It could be as simple as a bad plug wire or plug. Start at the simplest things as noted above and then work from there. There's nothing worse than ripping a motor apart to find out you had a disconnected wire.

I agree with Jody, check your plugs and wires first, and go from there. Good luck!

Run compression check on suspect cylinder, if 150 psi or better, rule out valve or head gasket problem, I think you have a ignition problem, plug wire, plugs, or distubuter cap.

you can also hook up motor to compressed air(via spark plug hole), make sure cylinder is a t.d.c.. where ever it leaks out through carb.,exhaust port,or valve cover oil fill hole, there's the problem. if it isn't plug, plug wire, something simple(i'm hoping for you)

IT sounds weird but check you timing there is a small chance your car jumped time by 1 or 2 teeth

IF THE HEADER PIPE IS NOT HOT THEN THAT CYLINDER IS NOT WORKING, THAT MUCH WE ALL CAN AGREE ON. USE THIS PHRASE TO HELP,FUEL AND FIRE. IF THAT CYLINDER IS NOT GETTING FUEL IT WILL NOT WORK. PULL VALVE COVER AND TURN ENGINE OVER TO SEE IF THE VALVES ON THAT CYLINDER ARE MOVING. IF THEY ARE NOT, THEN THE CAMSHAFT HAS WIPED A LOBE.IF ALL IS FINE HERE, GO TO FIRE. REPLACE PLUGS, WIRES, CAP AND ROTOR.WORKING ON CARS CAN DRIVE YOU NUTS AT TIMES. GOOD LUCK!
