My Nissan Sentra wouldn?t idle after mechanic changed distributor rod, kept dying at idle, took car back, told it needed a new manifold gasket, after having my car for two weeks, he tells me the car has an "internal mechanical problem and is blowing black/gray smoke. What could he have possibly done to my car??? He is telling me I need a new engine but it was fine before he got his hands on it. What possibly caused this?
I would suspect your timing chain tensioner broke and the timing chain jumped. Why did you have the distributor rod replaced? what is a distributor rod? It's possible the original problem was misdiagnosed. Timing chain jump will cause valve damage if it goes far enough in this motor. I'm assuming US and GA16i?

Mechanic could be an ass?
