Question about 1995 Buick Riviera
The dip stick is clean, no milky substance present. The motore runs good and no lack of power.
If there is an oil cooler (lots of newer cars have them), it is a separate assembly from the radiator, usually mounted in front of the radiator. No way oil coud get into the water that way.
Really the only place for oil and water to mix is from a leaking cylinder head gasket. Depending on where the gasket failed, you can get oil into the water, water into the oil, an external coolant or oil leak, or an internal coolant or oil leak into the cylinders.
Have a shop check it out. They can do some testing and find the problem. Oil in the coolant will not be good for your coolant system. It needs to be flushed and have the leaking oil stopped.

It is from a failed transmission cooler inside the radiator
Most likely the trans is ruined or will be from coolant

there are oil galleries in the had so that the valves and cam can get some lubricant so it maybe that in one of those oil galleries has a crack and same with the head gasket so it could be either one

SOURCE: OIL IN MY RADIATOR
Some cars are equiped with an engine oil cooler. I am sorry to be the one to tell you, but when the this cooler;s gasket fails, it will leak coolant into the radiator. It is a very hard repair that needs to be done by a good mechanic with a good reputation.Then on the other hand it may be a cracked engine head. It is either one or the other. Both are costly to repair. The cooler repair will go for about $400 plus labor. The Head replacement is probably more. You can weigh the consequences and see if you want to do this yourself if you are mechanically inclined. Sorry bro.

some cars with oil level warning light on, it doesn't mean that its only reading the engine oil level is low, sometime the transmission fuid too. Did you check your transmission fluid if it is ok or not? try to check and let us know, ok.

That's usually an indication of coolant (antifreeze) getting into the oil. It can mean quite a number of things. A bad head gasket, a bad head, a crack in the block, etc... Sometimes a product made by "Lucas" called head gasket sealer works. It's a pretty good product and cost around $30 a bottle. I'm not quite sure of what information you're seeking as the comment was somewhat vague. It's not a good idea to drive the vehicle with the coolant in the motor oil as it reduces it's viscosity and is sure to cause further damage. Change the oil and filter asap and give the Lucas a try. I hope that's what you were looking for as I would have difficulty going any further unless you comment back and clarify exactly what you are seeking.
