    Default oil in coolant

    hi, i took off my radiator cap today and took a look inside only to find really brown looking liquid. when i smell it i smells a little oil but i am not sure. there is no coolant in oil and my car is not overheating, what could be wrong?

    thanks

    Emmmmmm, if it was'nt oil then it must be rust. does it feel oily?? try to examine with tissue or something. also check the oil level. if there is an oil loss then it is blown head gasket.

    If its in your coolant, it won't be dripping down the side of your engine

    It gets into your coolant by breaching the headgasket between the head and block. You won’t necessarily see anything. At this point, you're best to find out whats in your coolant. Also, don't assume you need a noticeable loss in oil level to have a leaky gasket, you could have a bit of coolant going the other way and compensating.

    Don't want to worry you, but I'd be asking someone to analyze my coolant/oil.

    Good luck with it,
