today i was driving and i had a loss of power and alot of white smoke comming oout of my exhaust. then finally the car shut off and i couldnt start it again. i pushed it to the side of the road and sat for about 10 minutes, then it started again and still bogged all the way home. my check engine light is on also. i thought it might be the head gasket or i got water into my sprak plug because its raining here and my hood has holes in it. any help would be helpful.
