850 water in oil ...please hold the mayo

Just went to check the oil and noticed the oil has gone creamy, no over
heating no other signs oil under the rocker cover seems to be fine. just the
oil on the stick .

Any suggestions, any experience with non head off fixes?

I would change the oil, drive it some more and see if it comes back.
When I bought my 740 the oil looked like this, I figured at such high
mileage it was due for an engine swap anyway so I drove it a bit and the
problem went away and has never come back, I did find that the o-ring on
the dipstick was missing so maybe condensation got in that way, I'll
never know. Are you getting any oil in the coolant reservoir?

 

Condensation will do that if you live where such things happen. Skins
over the top of the oil but when you pull the stick, it's completely
covered below the full line because everything under the oil has to pass
through the skin on it's way out.
Get your stick all rusty too.
You use your car for lots of really short trips?
Like James says, drain it and see for sure.

 

I would mark the coolant resivour with a pen and watch it carefully.
Change engine oil and get flouescent dye you put in the cooling system
to see if its a head gasket. a Stop leak product might help but who
knows. Is it city short trip or hwy driven, is coolant 50/50
antifreeze, is temp high when running, maybe a bad thermostat. It
sounds bad you need to find the cause quickly.

 

Yes, change the oil and see what happens. It may be a temporary build-
up of condensation.

 

This happens when you do short trips and the engine doesn't get hot .In fact
often when going on a long journey people are tricked into thinking they
have a full sump of oilwhen in fact there is some water in it .When the
water boils off there is a lack of oil which is very worrying till you know
the cause .Once in high extremely high country and thick fog , my oil went
white with water .But it boiled off on the way home .
