What happens if too much oil is added to a 7. Over filling the oil isnt the cause of it. I could see it causing a gasket to leak or something but it wont cause blow-by. It could make the symptoms appear worse. The Powerstroke has such an efficient cooling system, that this low flow when the thermostat is slightly open is normally enough to keep the engine cool. As with any engine, too much will cause the crank to beat air into it, possibly causing oil starvation in the main and big-end bearings.
Specifically for a diesel, however, excess oil in the crankcase can cause it to be forced up past the piston rings and into the combustion chamber. From a reliability, durability or simplicity standpoint, the 7. When it comes to horsepower, drivability and meeting modern day emissions standards, the 6.
Ultimately, both engines have their pros and cons. Stock power the 7. More pulling power and I would consistently get 2mpg better with the 5. Empty the mpg were almost the same. Freeland has maintained the truck to a T. When a part needs replacing, it gets replaced and he gets quality parts fitted, like factory Ford parts. When it needs maintenance, it gets it. As far as tires go, he says Michelin tires are the best. Being a manual transmission and doing lots of highway driving means less wear and tear on the brakes.
Freeland says he gets about ,, miles out of a set of brakes. Which is crazy. Over time, residue sand enters and clogs the oil cooler. The oil cooler lies in the valley of the motor and it is where the heat from the oil is transferred to the cooling system. Because Ford built this oil cooler with tight internal tolerances, it clogs easily which causes a lack of flow and higher than normal oil temperatures. The result is often EGR cooler failure. Letting this issue go until failure can have a long-term impact on the longevity of your engine.
Luckily, you can avoid this serious and costly problem by installing a coolant filter kit, as well as a high flow oil cooler and an upgraded tubular EGR cooler. And if you have a performance tune, it will happen sooner rather than later. The damage done from such a failure can dramatically affect the life expectancy of your engine. Look for signs of coolant expulsion around the coolant pressure cap or residue around the coolant expansion bottle.
While you can still drive your truck in this situation, avoid adding extra stress to the engine by pulling heavy loads. The best time to fix the issue is before it happens by installing a new head gasket kit with upgraded Powerstroke 6.
TrackTech makes the strongest studs in their class and are competitively priced. They can be bought separately, or in a kit featuring Mahle head gaskets. For example, on and newer trucks, EGR valves contribute to increasingly dirty oil; on and newer trucks, particulate filters can create excessive back pressure; and emission control systems can spray and ignite fuel in the engine to burn off soot, creating high internal temperatures. These include heavy towing , oversized tires , and as we mentioned, a performance tune.
