You need to do a leak down test on the cylinders one by one. Remove the spark plug or injector if you have a diesel and air up the cylinder with shop air. Then with the radiator cap removed, look for any coolant movement. If there is any movement, then that is one of the cylinders that has the leak.
Not coolant, i ran the engine without water. It's lacking power, will do a compression test to confirm worn cylinders.
