Hit a major pot hole. continued to drive car when suddenly started to lose power going up a hill and engine started to tap. Car stalled as I was pulling off on side of road. Coasted to a stop at which point there was burning smell and a puff of blue smoke. about a quart of oil leaked out of the bottom of the car.
Was able to start car when tow truck came but turned it off quickly. Car is at shop now
Any thoughts on whether this is just a cracked oil pan or more serious engine damage?
