Default Smoking!

Finally replaced my MAF sensor; had to find a job and get the paycheck and such. So it sat for about a month and 4 days. Replaced, started it today..and I'm getting smoke from the....upper manifold maybe? Where the oil cap is, the thing it attaches to..but not the actual oil itself.

Just burning crud from 4 weeks of sitting still? Or a problem I need to look into?

I would chnage the oil after sitting that long. See if that helps any.

Planning an oil change next weekend actually.

1)It'* fine to drive it, would you think?
2)The smoke started out white and a good amount(not a LOT, but enough to see white), and is now a lot less and clear and thinner.

So it'll just burn it off and be fine? Or is there a procedure I should do before making her my daily driver again?

I would just keep a close eye on it and change the oil and filter ASAP

If your valve cover is smoking a bit, meaning just below the cap...it'* likely a bad valve cover gasket.

Is the smoke inside or outside the valve cover?

Outside, from just under the manifold, under the valve cover. Taking the valve cover off, there'* no smoke inside.
