Check for oil in the water or vice versa. Also, if you haven't changed the oil in a while it could just be burning the old oil. If you have mixing of the fluids, your car needs a head gasket.

yea i checked the oil & coolant.the coolant looks fine but the oil dosen't look bad in the pan ,but i took the valve cover off & the oil has a milky film all on the top of the head & valve cover.so im thinking im going to do a head gasket.thanks for your reply hellcat1988

Not a problem. Though I'd suggest that you replace your timing belt and water pump when you do the head gasket. It may add a bit to the repair, but it'll save you time and money down the road since you have to take the belt off anyway.
