A buddy of mine was driving my car like an ***, afterwards we popped my hood and saw that it was leaking oil from a broken bolt on my valve cover. The bolt was already broken from before but never leaked. Should i be worried? And when ever i turn on the air or heat in my car you can smell like an exhaust or gas smell?
Does anyone know what this could be. thanks for your time.

 

you were driving...

 

bump i would like to know as well too, because i have this same smell coming from my vents....

 

i recall you driving

 

I hope no one helps you mike.

 

please help

 

Im sure if he drove it hard it force oil to come out the loose bolt, if it was alot that might be what your smelling. replace the bolt from the dealer its like $1.50.
Or you might have a coolant leak from him driving real hard, in eathier your upper or lower rad. hoses or your throtlebody hoses run your car and feel all over your hoses with your fingers and try to find the leak. check under the car as well. and last never let anyone drive you car...
