Really? Mine burns 1 Qt per 400 miles, crank seal leaks really bad, 30K miles of hard driving since I noticed a problem. Started 1 qt. at 1500 miles, now 1 qt. every 400 miles. Car runs best when fuel quality is perfect(PS Diesel Kleene seems like white-magic to this car). Getting 24 - 26 mpg.

Afraid of a compression test. Cylinder 1 is definitely the culprit. Other than the loud knocking and throbbing and oil smells with each tick-over, it runs nearly perfect otherwise. She starts cold pretty well, too.

Still, the miles keep on rolling by.

Yes, the engine in question is a longblock replacement with the upgrades.
