I patched up the oil pan and got it going and it sounded great. We let it run for a half an hour or so and there were no knocks, overheating, smoke or oil light. Unfortunately we discovered that when he hit the pothole he also broke off the motor mount bolts that go into the block and the motor would have to come out to fix them so I'm going to change the motor anyway. Also, I see now that it has the 2.4L, not the 2.0L.
Here is where the broken off bolts were.
How much fun is changing the motor going to be? At least I have access to an engine crane and low 4 wheeled cart to slide the motor out on and possibly a hoist if necessary.
