Late last night Me and some of my friends were driving around my town looking for my friend (long story) when we parked at the local Walmart. I noticed an interesting smell that is quite hard to describe. It seemed to be a combination of a typical hot engine mixed with something burning/old something. lol I checked my coolant reservoir and it was a little low so I filled it up. The exhuast smells normal any ideas of what it could be? and should I be worried? I was thinking I should change my head gasket is this a legitimate worry.

 

did it smell kinda like a rotten egg?
there doesnt seem like enough evidence to say a head gasket.
i wouldnt worry about it just keep a eye out. and if anymore problems pop up let us know.

 

Check your exhaust, you may have some plastic bag melting under your engine.

 

lol if you carry oil around in your car with you, make sure it diddnt spill, mine did, it smelled like burnt oil for a few days then when i went to fill it up, i seen it spilled over.. i had alot of fun cleaning that one up... lets just say lowes wasnt happy when i returned their rug scrubber lol

 

lol no I don't have oil in my car but I do have other fluids and they haven't spilled but that is a great story. and yes it smells similar to a rotten egg combined with a typical hot engine. It hasn't really done it since I added fluid.

 

Catalytic convertor.

 

yea the rotten egg smell is a sign of a bad catalytic convertor, thats why i asked.
