Hey all! I have a 2001 Ford Ranger with the 4.0 SOHC engine, that has 130,xxx miles on the clock. About a week ago, I went to change the oil and noticed the rear of the oil pan was damp. I cleaned the area, added dye, and have since driven about 400 miles. The pan is just barely moist and my mechinic says that it looks like the oil is coming from the "girdle" gasket, or what the dealer refers to as the upper pan gasket. He suggested (given the age of the truck, the slow nature of the leak, and the expense of the repair)that I leave well enough alone and add a quart of Lucas Engine Oil Stop Leak. Any advice is greatly appreciated!
