My engine is a 24 valve. Out of the blue the motor started making a big pounding sound which revs up with the accelerator. My guess is a blown piston but since it has never had problems I am a bit curious. Someone said injectors make a sound much like a blown piston, is that true?

If its more like a thumping sound could mean main bearings
