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

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.

SOURCE: Oil level low light comes on. When I turn

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.

SOURCE: sludge milky brown oil on dipstick

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.

How do i check for oil ?

Look for the dipstick marked Oil. It is usually yellow or red. With the engine off, pull out the dipstick. Wipe the dipstick clean and place it back where you got it. Pull it out again and there is a set of marks on the end of the dipstick marked full and low. If the oil covers the low mark but not the full mark you're okay. If the dipstick is still clean then oil will need to be added until the oil appears on the dipstick between the marks.

I haven't seen such a dip stich but as dipsticks have a full and low reading on them then it would be logical to say that the top and bottom holes will be full and low and the holes in between would represent the number of pints needed to bring the oil level back to the full mark . So lower is I pint in the sump ,next hole is 2 pints , next hole 3 pints , next hole 4 pints and top hole 5 pints.

2007 F350 diesel. Died at a traffic light and wouldn't start. There is oil in the radiator overflow tank and the oil gauge doesn't register.

It sounds like a head gasket problem. A Radiator pressure test may reveal that there is a bridge between water and oil. This is not a guarantee because escaping oil is pressurized from 40-65PSI and the water system is in the neighborhood of 16-18PSI so there is significantly more oil pressure than water pressure. In short, it is easier for the oil to get to the water.

Another test would be to remove the Glowplugs. You may only have one bad side and if the antifreeze blows out the holes for the Glowplugs, you may only need to remove 1 head.

Check your dipstick. See if oil is mixed with water in crankcase.. Check oil level to explain action of pressure gauge.

Engine light comes on and says engine overheating

Could be three things: Hopefully the first...
1. radiator fan not blowing. (most likely)
2. Radiator clogged (not likely)
3. Head gasket blown... (very possible)

If #1, system cannot detect fan not blowing. It may be the fuse or the relay switch, disconnecetd wire at fan, or burned-out fan motor.
If #2, Flush radiator
If #3, you will see WHITE smoke out the tailpipe and excessive water drops.
Your new oil will have a "milky" look (check the oil dipstick). That is water.
When engine is COLD, remove radiator cap and start car. You will notice high-pressure "bubbles" squirt out of the radiator, even before the engine warms up.

I hope it is #1. and that this is helpful.

Losing oil on E46 316i 2003

hate to be the bearer of bad news, but i think your head gasket has failed causing the oil & water to mix in the engine. usually, the water enters the oil causing the milky cream liquid (check the under side of the oil fill cap for this same creamy liquid) and you wind up adding coolant since it gets low.

if the coolant is not getting low, then it may not be anything to worry about. in the colder months, BMWs have been known to display this creamy liquid on the oil cap. it disappears when the weather gets warmer. BMW has a service bulletin on this.

have a compression check done on it to see if this is truely the case. i hope i am wrong. and 1 pint every 2-4 thousand miles is not too bad.
