 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 overpressurizing 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 is an extreme.
