Just curious if a bypass filter would help this
Just curious if a bypass filter would help this car. Its a 2008 BMW 750LI 4.8 LTR. It runs very hot and has a known issue of the valve seals drying and becoming hard , this allows the oil into the combustion chambers. To repair this problem can cost in the thousands so I am hoping to find a solution. Some have suggested running a lower temp thermostat ,that will make the motor run cooler but I've been told you sacrifice fuel millage which is something id rather avoid. I am seriously looking at a bypass filter as a means of 1) allowing the oil to be cooler. 2) the oil will be cleaner so the engine being an aluminum block will hopefully get more miles due to the cleaning effects of a bypass filter. 3) since a bypass adds an additional liter of oil , it would benefit the engine oil running cooler but would help not to cook the valve seals. 4) running the oil longer between changes. if this is all true what would be the best Bypass filtration system ?
A bypass filter will cool the oil Its bringing the oil outside the block and heads where the filter is and faces ambient air at velocity). A bypass filter will clean the oil. As a result there will be significantly less wear on the engine internals. These are documented facts. Engine longevity is determined by additional variables (overheating, etc.). If cost is an issue buy the parts and tools and do the value seals yourself. If you can't do that and don't want to pay someone to fix that, perhaps you can try a high mileage oil that MAY revive the seals. But it sounds like you want to drive a 8 banger BMW . If that is the case then maybe you need to adjust your perspective on what you can realistically drive given your financialy outlay and skill ability. If you really love the car, you might want to consider developing the skills to keep said car.
