White Smoke out of Tailpipe

So last week I noticed a large amount of white smoke coming out of the tailpipe of my 04 Silverado. I did an oil change since it was due and put some Lucas Oil Treatment in with the oil. It is still producing the white smoke when I first start out in the morning. What is my next step? I really want to do the right thing, because I need to have this truck for as long as possible.

Thanks.

You stated just when you start out in the morning. Does it go away after driving for a while?

Do you do a lot of short distance runs?

Moisture may be accumulating in the exhaust system, then when the exhaust heats up, it steams out the tail pipe.

If it doesn't go away, or gets worse after driving for a while, I would suspect coolant is getting into the cylinders. Have the system leak tested.

I only notice it when I start out in the morning. My job is about 15 miles one-way. I haven't noticed any abnormal oil consumption, but I seem to be going through coolant more than I would think is right. I haven't replaced the PCV valve since I bought it in '08. Thanks for the help guys.

Sounds like a head or intake manifold gasket leaking. You shouldn't be going through any coolant. If you are having to fill coolant, something is wrong.
