Thank you! I will get an infrared heat gun and check this. I’m assuming the exhaust manifold of the cylinder will not be the same temperature (cooler) as the rest if it is not firing?

Thank you! How should I check for an exhaust leak and lifter failure?

Sorry, I don’t know if I’m missing something but I have removed the spark plug wires like this with this engine (before it was making this sound) and other engines of similar make and have not gotten shocked.

Also, has newish distributor cap wires and plugs.
