 So, you know, all of a sudden you develop a blow-by problem or too much crankcase pressure problem. You know, you're actually pushing oil up into the combustion chamber, and it's working its way back up, and you're over-pressurizing the crankcase and, you know, having those issues. That being said, all right, there's two approaches I would do, because the third approach would be pull the engine and re-ring it, which I don't think is practical at this age in mileage. You know, if it's working, three-quarters of a quart in 2,000 miles really isn't extreme.
