I garage working, engine smoking help!!

Hard to tell from the pic. If it's not where the transmission brace goes, plug it. It may take an NPT thread plug. If it stops smoking, then that was your problem, if not, keep looking. The rear of the intake manifold is a fairly common place for leaks.
Before going through all that trouble, do you have a breather cap towards the rear of your passenger side valve cover? If so, smoke will sometimes come from there, starting as soon as you start it.
