If your using alot of engine oil. I would suspect you have a bad plenum gasket. There is a steel pan bolted to the underside of the intake manifold. The intake is aluminum and the pan is steel, they contract different to heat. Thus the gasket has a tendency to push out or leak. Park your truck on a flat surface and let it sit for a couple hours. Then take the air intake off the TB (throttle body) and shine a light down in the TB, while you hold the throttle blades open. Should see some oil puddles. If your half decent with a wrench, you can fix it yourself in a couple of hours. Have to take the intake off and replace the pan with an aluminum pan and new bolts, and intake gaskets. I got one from hughesengines. Com for around $80 bucks. Comes with new bolts, pan gaket, and 1/4 inch thick plate. The intake gaskets were seperate. As for the antifreeze, could be leaking from the pump and burning off there fore no wet spots on the ground. Is your pass. Side carpet wet? Could be a heater core. Hard to tell when your not in person. Ps if you do decide to do the intake repair, replace the little by-pass hose from the intake to the pump. It is underneath the a/c compressor. It will never be that easy again! Trust me.
