After the last run I have noticed that there is a small leak under my truck after it is parked for a while. It will drip when is parked, and then it will stop in a day. There is no fuel in the crankcase. I'm not really sure it is fuel (very light pink) but when it dries from the concrete you can't see any spot, so it can't be oil.
Here are few pics from where I think it leaks. Also in the last pick you can see a vent tube of some kind, what is it for? Thanks.

Bottom - you can see wet by the pink tube with clamps:

The vent tube?????

Looks like a trans line and ATF.

The 2006's had this issue. It is the clamps on the heater coolant line in the first picture you took. Tighten those up and it should be gone.

The vent tube you see is the crankcase vent tube. It is normal to have a little oil coming out.

Thanks, I did not think about coolant, but it makes sens, as it was leaking only after the run (pressure in the system) once it cooled down there was no more leak. Thanks again, will tighten it up and see what happens.
