[blazzinbird]

is it common on these suv's? If so what seems to be the source?

What year, truck, motor etc etc etc... a little more info would help.
Sometimes, and i know this sounds crazy, if you get a flashlight, pop the hood and get under the truck YOU will prob be able to see where YOUR truck is leaking oil from....just an idea

If you're a DIYer, you'll need to safely put the car on ramps or stands and have a look at it as @Galante said. The truck's almost a decade old and you may get the odd leak as gaskets and seals age.

These things are known to leak around the oil pan, around the block off plate for an oil cooler, and the rear main. As said prior, though, you are going to have to visually inspect to see where.

Our PPV started leaking out a seal on the oil cooler adapter just above the oil filter. The block off plate gasket can leak, too, but rarely. Some have also had the oil pressure sending unit at the top back side of the engine leak.

We also had a VERY loose oil filter when we got our truck. I got under it to change the oil, and bumped the filter with my hand while putting the filter wrench on it, and it moved. =8-0 It wasn't leaking...... yet, but that's another place, especially if someone's changed the oil and the old gasket stuck to the engine.

Lots of places to look.

My oil cooler lines are "sweating", not enough to drip but the hoses are getting old. New ones sitting on the work bench waiting for time and cool weather.

Is yours leaking?

Like swathdiver, my oil cooler lines are in need of replacement and have been waiting patiently for me to replace them

Post some pics, maybe we can diagnose it for you

Had a full oil pan set replaced on our 2008 Tahoe Hybrid 6.0 L at about 130,000. Did not notice it till about 129,000; watched it for a thousand miles and then got it fixed when I knew what was really leaking. Never leaked enough between changes to have to add any oil. Never leaked on the garage floor till just before I had it fixed (I think that was actually from a spill onto the cross-member when we had it serviced and they pulled off the old filter). Really did not have to have it repaired as it was not that bad, except I just hate having anything wrong with any of my vehicles.
