This northstar engine has leaked oil,(not burning it) since 40,000 miles. I use 2 or more quarts of oil between oil changes. It leaks whenever it is parked. I have spent monies on this, but it appears a major engine repair is needed. Some say, the bolts were too short, and others say, this defect continued until the 2006 year.
