Sad Day for Corvair, dead cylinder
Posted by: 4wd430 ()

Hey guys, unfortunately my Corvair has a dead #1 cylinder. The car has been noticeably misfiring and I have always had a puff puff chugging sound with the car running.

I unplugged the spark plug wire off from the distributor while the car was running and there was no change in the engine speed. The only thing that seemed to go away was the puff puff chugging (misfire) sound. There was also no arching from the wire so it isn't getting any power.

Tomorrow will be a compression check and might take the valve cover off for a better inspection. Pretty bummed about this, seems like all I am doing is spending $$$.

Here is the video of the chugging sound:

Could be a head gskt. Try checking torque on that head.

Did you get your dist figured out??

I have all new wires in. Had the miss even with the old wires. I was going to get help with points, condensor and timing but want to get this figured out first.

Plugs are also relatively new and swapping the #1 plug with another didn't change what happens.

If the plug is not getting high-tension voltage (the arc - a spark from the wire end itself) There is your problem to check first.
Perhaps the cap has an internal carbon-track short that kills that plug wire, new or not.

Check out the cap inside, check for corrosion in the contacts in the tower that the wires plug into as well.

It could be a lifter adjustment too tight and a valve is staying open. A weak cylinder is not necessarily dead.

Are you sure you put the plug wires in their correct location?

Before all of the more involved checks are performed, if you know there is no spark at that cylinder, you have to fix that first. All of the compression checks, valve adjustments and other tweaks are meaningless if there is no spark.
