I'm noticing oil spots on my driveway. A quick look reveals oil droplets hanging from the bolts which hold the oil pan from underneith. Without putting the truck up on a lift and doing an inspection, my "guess" is that I've got a leaky gasket. I snugged the bolts on the back of the oil pan but that didn't suppress the leak (not surprised). I recently changed the oil after having the injectors replaced. I smell no fuel in the oil when dipping my finger into the drops- smells like engine oil!

I sounds like this oil pan is a 2 piece deal. Any guess as to what it might be from? I'm guessing that, since the oil is on the pan bolts, it's not the rear main seal of the crank. I'll find out more after I take it in to the stealership and have them look at it.
