i have a 2001 Mazda Millenia V6. It's been parked a few months because of an engine issue. I was driving down the road and hit a pretty nasty pot hole. It broke the front driver wheel mount, but that's not the beginning of the problem. After I hit the pot hole the car just shut off. I pushed it half a mile to my mothers and it's been parked there since. I've had 2 mechanics look at the car and they can't figure out what's wrong. It had an oil change a few days before the incident, but when my mechanic looked at it, there was no oil in the engine. He added 2 quarts of oil and ran a pressure test on it. The engine is not holding any pressure. There are no fluid leaks and the head gasket it in tact. Can anyone tell me why the engine has no pressure? The car will try to turn over but will not start.
