Well 1st you need to have the leak down test gauge or kit, Then you set each cylinder to where the intake and exhuast valves are closed, next connect a compressor hose and pump the engine full of air. The leak down test guage set has a gauge that will tell you how much air you have bleeding down. Sorry these directions arent exact but these steps pretty much sum up what must be done.
