do you mean the cylinders?????

possibly worn piston rings

take it to a garage that can perform a leak-down test to determine where the compression is escaping (intake, exhaust, crankcase, gasket, etc.)

a compression test is done by removing spark plug and plugging an instrument in that tests compression of each cylinder, not the valves
