Constant high speeds

Just curious if driving at 140+ for extended periods of time

would cause more oil blow thru, or help burn off the carbon that may build up on the intake valves on a N55 motor?

Its more the engine rpm you are running than what speed you are going, the speed is irrelevant. If you are running at a higher rpm than normal there is gonna be more blow by yes. Its probably not gonna help burn carbon off in any way...
