Apparently one of the common problems with the 6.4 is plugging of the coolant portion of the engine oil cooler, there fore no longer being able to remove heat from the engine oil. This kit from BulletProof is suppose to take care of most of that in a easy DIY kit, which also includes a heavy duty spin on oil filter that replaces the OE filter and delicate filter housing in which drain and bypass valves have been easily broken......can't wait to install it this weekend
