Problem with 225 in my New Truck

I just did a little more digging and I'm afraid I have a problem. With the hose pulled off of the breather, I could see a pretty good flow of smoke out of it. Also when I pulled the PCV valve there was very little vacuum being pulled through the hose at idle.

Check for a clogged PCV port at the base of the carburetor and on the intake manifold's carburetor mounting pad. And make sure the PCV hose isn't holed or cracked. Also make sure the PCV valve is the correct one; see here for a story about that.
