I have had an oil leak that the dealer can not find now for months and months. It leaks on the ground in the driveway/garage and I have given up.

The truck has 16k on it, oil changed every 2k, M1 5w-30 or 5w-40. By the bible.

When we left for our 500 mile trip to our destination I cleaned underneath the truck and got all the oil off the bellhousing and oil pan. It was spotless. By the time we got there it was smoking from oil on the exhaust, and completely soaked underneath. Obviously there is a leak somewhere

Or there WAS.

The oil level stays just a pinch under total full with 6 quarts.

Once we got to the inlaws, I then again cleaned underneath the truck and got all the oil off, scrubbed everything down with a brush & degreaser. Yes I'm a bit anal.

The oil level just dropped a hair. Most people wouldn't notice it.

So the drive back -- 500 miles, 65-75mph, a few stops here and there.

I check once we get home and not a single drop of oil anywhere.


What gives?
