What causes loss of compression in a cylinder?

There are several causes you can eliminate if your cylinders are losing compression. … Exhaust valves and air intake valves at the top of the cylinder can also get overheated, and leak gas or the valve seals can become too worn to seal the gas in properly. Either way, the result is often low compression.

What happens if one cylinder goes bad?

A misfiring cylinder can cause a proportional loss of power. For example, if one cylinder misfires in a four cylinder engine, the car will lose 25 percent of its power. … Damaged, worn, or bad spark plugs, or a weak ignition coil can cause a loss of spark, and therefore, a misfiring cylinder.

What would cause a cylinder not to fire?

Causes include worn, fouled or damaged spark plugs, bad plug wires or even a cracked distributor cap.
