Smoking 318 need some ideas why?

Lots of good ideas guys, heres an update.

This morning I bought a quart of the Mavel mystery oil, and added it to the engine.

I also checked the intake manifold bolts and half of them were not very tight at all.
So I tightened them all up a bit.
Fired the car up, no smoke as usual on startup. I took the car out for about a 1/2 hour drive, open it up real good a few times, pulled up some long hills in drive, and then kicked it down to second. Basically gave it a good work out.
Stopped once while I was out to check for smoke, and then got out and watched the tailpipes at idle when I got home.
Just a little smoke from the drivers side tailpipe, but overall, much better than it was a couple days ago.
Seems to be a lot of rusty looking water being blown out the tailpipes, must have been a lot of condensation in the exhaust system. Like I say, over the last 2-3 years all i've done is start it once in a while to move it in or out of the garage. Today it got a workout.

I'm thinking it was half the intake bolts not being tight, and the rings either being stuck or not seated well. At any rate, I think the smoke is minimal at this point so I'm going to go ahead and drive it to the car show on sunday. Thats a good hour drive each way, mostly at highway speeds. Lots of big hills on the way, and places to open it up.

Its like Bill cosby used to say, "I was just burnin' out the gunk officer"

p.s. when i had the plugs out to do the seals, the plugs were not oily looking at all, but were covered in black soot. Probably still running rich, or maybe cause every time I start it, it just runs a few minutes, mostly with the choke on.

If it still smokes at all after this weekend, i'll probably pull the intake and replace the gaskets.

The car does have a pcv valve in one cover, and a breather cap on the other side. Although i'm not sure how to test the pcv valve.
