It won't need pressure, just flow. And possibly an expansion tank.

Been there, not enough air flow in the rear of the vehicle. Oil to air would be fine in the high-pressure area of the front, but then the oil has to travel 30 feet. Simpler, but more strain on the engine. > A pertinent question may be: Is the stock cooling system and oil cooler > working properly?

It seems, to persons not directly involved in my project, that the stock cooler should be sufficient. But you need to take into consideration the workload of my turbo engine, pushing this non-aerodynamic 4WD beast with oversize tires and high gearing up and over 10,000 to 14,000 ft. mountain passes loaded down, all the time very close to full boost. Now THAT makes a lot of heat! In stock form in a stock van, no problem. Or with no turbo, with it's bearings being cooled by the oil. The stock oil cooler being cooled solely by the engine coolant works just fine, until I hit those long passes. I don't think 150 C. degrees is so good for oil, do you? Karl |
