What are the symptoms of a broken valve spring?
Broken valve springs cause excessive valve noise, compression loss and can cause severe internal engine damage. The actual breaking of the valve springs is not always the most serious consequence. Actions following the breaking cause the most serious damage to the engine.
What happens if valves are not seated properly?
Engine Power Loss If your valve guides and seals are leaking, oil can accumulate on the top of the valve and cause it lose its seat or create a gap. This could cause compression issues, which lead to poor combustion and power loss. Have your oil changed regularly, and fix any other engine problems promptly.

Will a burnt valve cause low compression?
Poor Engine Performance A burnt exhaust valve can also reduce the performance and power of the engine. Burnt valves can tend to have huge holes that will leak out all the gases. This eventually reduces the compression, resulting in the poor performance of the engine.
Will a burnt valve cause a misfire?
Bent or burnt valves can also cause your engine to misfire. This means the engine may jerk, stall, or hesitate when your car is in motion. Your vehicle’s fuel consumption could also increase if it is misfiring due to a bad valve. These are some of the many symptoms of a bad exhaust valve or intake valve.
