get a compresion test done,your head gasket may need replaced....if youve already replaced the head gasket ,did you get the head skimed?I have oil in my radiator?
Intake manifold gasket may not be installed correctly. Read the ';GM Litigation'; web-sites. GM has lots of engineering woes, including their V6's. How do you know that there is oil in the radiator???? Dex-Cool has been proven to be a problem. It discolors and may LOOK like oil. Have the cooling system flushed out and use Mercedes Benz coolant. It will last for 150,000 + miles and will cause NO problems with compatibility of gaskets and pump bearings.
How do you know it's oil in the radiator? Do you see a ';film'; on the top of the coolant in the radiator? If so, that may not be oil, but residue from the radiator being manufactured. It's not great, but it won't cause the problem you're complaining of. But if coolant gets into your oil you will get white smoke from your exhaust and it will run rough. If you have white smoke, then there is a head gasket gone, or something even worse (cracked head).





Do you have a ';check engine'; light?
Almost sounds like you still have a head gasket leak. Also check your spark plugs. In some cars when your gaskets go oil will seep upwards and get into your plugs.
a crack in the head and its burning coolant.
