i have a 98 v6 camaro, my first car, i got stuck in my yard yesterday after washing it and after trying to get out i started to realize smoke coming from my tail pipe, when i brought the car i was told the rear main seal was starting to leak but im a college student and havent been able to get it fixed yet... is that the reason for the smoke or is it something bigger?

 

You just washed your car. Water gets in the tailpipes = temporary smoke.
