oil in radiator

i change my intake gasket today,but the dip stick look good, but inside my radiator light brown color or is it my head gaskets.

might just be rust in the motor if the oil is still good

Light brown wouldnt be oil, more likely rust. Drain the coolant and look at it in the light. If you see a rainbow you got oil in the rad and THEN you are hooped. Thats the head gasket.

Now check your oil. Chances are, It'll have the same look too. BTW, if it looks like a chocolate milk shake, then oil and water are mixing somewhere. NOT GOOD! Get it fixed ASAP.

Your probably striaght, I thought this once, but it turned out to be just rust in the radiator, wouldn't hurt to get it flushed and checked out.
