broken rings,hole in piston,bad valves
Oil leakage and loss of compression and power loss.
Loss of compression is caused by bad internal engine wear or internal engine failure. Both mean the engine will need serious repair
If you have loss of compression then a full rebuild of the engine is most likely needed.
The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.
You can check for lost compression in your engine by conducting a compression test, which measures the pressure in each cylinder. If one or more cylinders show significantly lower readings than the others, it indicates a compression loss. Additionally, symptoms like rough idling, reduced power, excessive exhaust smoke, or unusual noises can also suggest compression issues. Finally, a leak-down test can help pinpoint the source of the compression loss.
It won't run, that's for sure. Diesel is ignited by compression pressure, not by spark. And the compression in a gasoline engine is not sufficient to ignite the diesel.
If the compression is high enough you get a diesel engine.
During the compression stroke in an internal combustion engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the mixture, preparing it for ignition.
Oil burning or loss of compression on any one cylinder. It may also be missing on one cylinder. A compression test will verify this.
Low compression indicates that engine damage already exists. An engine's compression will be lost if: there is damage or wear to the pistons or rings there is damage or wear to the valve train there is damage or loss of seal on the cylinder head There are some other factors as well, but these three cover most.

No compression in three cylinders of a 454 engine can be attributed to several potential issues. Common causes include a blown head gasket, damaged piston rings, or burnt valves, all of which can lead to loss of sealing and pressure. Additionally, a cracked engine block or cylinder head could also result in a loss of compression in those cylinders. Diagnosing the specific issue would typically require a compression test and further inspection of the engine components.
A loss of compression in a 3.4L V6 Chevrolet can be caused by several factors, including worn piston rings, which can lead to inadequate sealing in the combustion chamber. Additionally, damaged or burnt valves can prevent proper closure, allowing gases to escape. A blown head gasket can also result in compression loss between cylinders or into the cooling system. Lastly, issues with the engine's timing, such as a slipped timing belt or chain, can disrupt the engine's operation and affect compression levels.
