I had to replace the alternator belt yesterday. I accidentally lifted the car alittle bit by the oil pan accidentally. I thought I had the jack deep enough to reach the circular parts of the subfrrame K brace, but of course not.
I corrected the issue quickly, but now my car sounds like it has a new rumbly exhaust, and the engine is tilted upwards.

I didn't notice the engine tilt until after I test drove the car, and it's overheating. The hood is rubbing the plenum now.

I think I bent the oil pan to where the pickup tube is starving for oil.

It's raining now, so I can't jack the car up and inspect it.

Feel free to take shots at me, but I'm looking for what to look for, motor mounts destroyed, etc.

 

The oil pan is pretty strong when bolted in place, but if you lifted the front wheels off the ground before realizing the mistake, then it's possible you caved in the pan and damaged the pickup tube. This would be very obvious with a quick visual inspection. More likely, you damaged or broke the engine mounts. The OEM mounts aren't the strongest and they are at an age where the rubber starts to crack from dry rot. Depending on how much the engine was lifted, you could have also created an exhaust leak at one of the flanges. The flex-joints on the factory Y-pipe can handle this level of movement, but if you have an aftermarket solid Y-pipe without flex joints, then odds are you either bent a flange/pipe or destroyed a gasket. If the hood is rubbing the intake plenum, then it sounds like the motor mount guide studs into the subframe or engine brackets are bent, broken, or misaligned. The engine should be sitting back where it's supposed to be after removing the jack.

Fingers crossed the overheating issue is a coincidence. If the lower oil pan did not cave in then I doubt you have an oil starvation problem and this could be a coolant circulation issue. Have you done any other work recently involving the coolant system? Have you noticed any oil or coolant leaks around the engine since this incident occurred?
