there is engine oil in my e46 radiator but there is no water in the engine or my dip stick. flushed once but after three weeks the oil is back. pls help me on this.
I haven't worked on a bmw in a few years. Does it have an oil cooler built into the radiator? How do you know that it's oil? When you were checking your oil for water was oil level low? Did u overheat the engine lately. Is it a stick or auto trans? Plz answer the questions the best u can.
there is no oil cooler in the radiator. very clearly engine oil. oil level normal. no overheating.
Is it alot of oil that u r seeing? If it was your engine oil getting into the radiator the oil level wouldn't still be full. Engine oil doesn't expand when its hot like automatic tranny fliud does. It's 7am here in FL. and I'v been up all night the last two days w/3-4 hrs of sleep in between. Let me sleep on it a bit and see what I can come up with.
Kugan google 2002bmwm3e46fluidcontaminationinradiator when it pops scroll down and there looks to be others with your issue. I don't have time right now to find exactly what you needed. So go check it out if you get this message before I get back later.I hope It's useful and not a deadend.
Same problem! Oil in rad but using engine oil would this be a split oil cooler ? Tony
The problem is the oil selector under the intake plastic mainfold. It's worn out. Change it and flush the radiator. Then the problem is solved
Guru96W7Y I have oil in my coolant also but no water in my oil. Call you provide a better description of the "oil selector" that you stated has failed in your previous answer?
I think some e46 I have transmission oil coolers that fail in some way to make this happen .it may look like oil but it could be trans fluid ...
If it's oil in water and not water in oil it's either trans cooler or oil filter housing gasket
It's actually a problem with the oil cooler. Its mixing transmission fluid with radiator coolant. Oil cooler is just down the radiator. Have it changed.
Hi its not engine oil its ATF mixing with the rediator water...when you drain your gearbox ull see the oil have a pink colour...replace the oil cooler

Hi I'm a bmw tech. And 318 have the head gasket combined with rubber head gasket at the very front of the engine where the chain pass by. Very common you need to replace head gasket every 60 to 80 thousand miles 770 881 5577.
