Remove the valve cover and the rockers so you can manually lift the valves to closed position. Once you pressureize the cylinder it 'should' keep the valve closed and tight. If it won't close all the way or you hear air hissing you may have a bent valve. If you have a bad gasket you can hear air in the radiator. If you're losing pressure but don't hear hissing then you might have loose or bad rings. If you have bent valves then the only way to fix it is to pull the head. This will also give youy access to the pistons. The leak down test will indicate if the rings are sealing. You'll also need to remove the timing cover to replace the belts and check the cams for damage as well. |
