Overheating then this

Hello all, I've been having a weird overheating issue on my 2011 X5 35i 65k miles. Took it to the dealer Nd they told me that it was due to a loose hose they tighten it and added about half a quart of coolant that was gone. On the way home I started hearing the fan on and off then when got off highway about 10 minutes later fan when on full blast and the drive moderately warning came on.

They told me the water pump is fine and until there is a code is hard to diagnose. But today I checked the oil cap because right before the over heating issue started I noticed that my oil level when up without adding oil it when from 1/3 quart up to full green. I found a milky white residue on it an right on the inside of the oil intake. Here are some pics.

Engine starts fine, no vibrations, no white smoke.

Some guidance would be gladly welcomed.

Not an automobile expert by any means, and certainly not BMW's; however, I have seen a milky film in my Tacoma at one point (no issues with the vehicle at all). In doing some research I found this is caused by the oil getting foamy and the water condensing and mixing with the oil and is not abnormal or harmful. These pictures look similar to what I found.

I will say given my experience and you DO have a problem, it would seem you have a head gasket leak, or some other internal leak allowing the coolant to mix into your oil system. I would not be able to explain, though, why the oil level would then go back down, once cooled, unless of course it is actually isn't (and that info is not in the description) OR it is evaporating or leaking back out. Wait to see what some of the other guys think before taking any drastic of costly actions. Cheers

Thanks G550Mech, sorry if I confused you the oil level after being . 1/3 down on the green bar when back to displaying full green bars without adding oil.

You could send a sample of the oil to Blackstone Labs for analysis. They will tell you if the oil condition is normal or not, and more about the health of your engine.

Hello, so after taking it to Atila BMW Master Tech. At Vanos Motorsports in Carlstadt this what was found. He plugged it into the scanner, 2 codes for water pump, operating under threshold and or obstruction so yeah the water pump is dead. He will replace thermostat and waterpump, do coolant flush and new oil change plus code the tailgate to close from keyfob and inside button all for $1200.

He did the co2 test came back negative, compression was fine. He asked me if I had added oil recently I said yes Castrol Edge Synthetic. He said ok thats your reason for the white oil viscosity most likely the car had Mobil in it and when Mobil and Castrol mix you get that oil foam.

A witch doctor's narrative.

It is 'soap' made of saponified motor oil and high pH coolant exhausted of its additive package.

Tough to say whether that emulsion is normal cold weather, short-trip condensation or a leaking gasket.
I'd check for oil in the expansion tank and consider replacing the oil filter housing and oil cooler gaskets.

I would say that soapy emulsion in the expansion tank is diagnostic of oil in the coolant, and I can't think of a differential diagnosis.

Free oil, not emulsified, in the exp tank is a sign of a failed oil cooler gasket.
