If you look at the center top of your engine you'll see the "spider" (hunk of metal w one tube left, one right and 2 down to the engine. At the spider you have 4 rubber boots and total 8 clamps. Then if you follow each arm from the spider down to the intercooler ( front of the truck) you will find the other 2 boots w 2 clamps each. If any of these have excessive oil you have a leak. You can do a "search" for intercooler boots for more info. Hope this helps.
