i was driving home from work and the only way to get to my house was through a 3/4 foot deep puddle after a serious rainstorm we had well i made it 3/4 way through this puddle when my car stalled ... my air intake was full of water and it looked like my combustion chamber was also ... after flushing the water out my car made a serious rattling noise when i started it ... does this mean my engine is totaled ?
