   Compression loss arises when the gasket is either too thick or too thin. If a gasket is too thick, it increases the distance between the cylinder head and the engine block. This can reduce cylinder pressure, leading to poor engine performance. Research from the Engine Research Center at the University of Wisconsin suggests that a compression ratio outside optimal ranges can result in significant loss of power and torque.

4. Uneven Sealing:
   Uneven sealing is a direct consequence of an incorrect gasket thickness. An uneven surface can prevent the gasket from making full contact with the engine block, leading to potential air and coolant leaks. This situation often results in misfiring and poor engine performance. A study published in the Journal of Engineering Design in 2021 highlighted that maintaining a uniform gasket thickness is critical for achieving desired performance standards in automotive applications.

5. Increased Engine Wear:
   Increased engine wear can occur due to incorrect gasket thickness, often leading to accelerated deterioration of components. The additional stress from uneven pressure distribution can wear down pistons, valves, and other parts more quickly.
