I'm doing the valve cover gaskets, and found a little milkshake. Shows up under the oil fill cap, and in one oil "pocket" on the passenger side head. No milkshake in the rest of oil in the head, and no milkshake on the dipstick.
Is it possible this is condensate, as opposed to oil - coolant mixing?
It's possible it's condensate. Usually see that on cars that only do short drives and don't get fully hot enough for any condensation to evaporate. I would clean it all up really well and monitor it. Does the coolant look good?
How does your driving pattern look? Most likely its from short drives (I also have some mayonaise under my oil cap during the colder winter days combined with short trips). Take it out for a longer trip and report back, if you still have it then it might be coolant related
you'll need more than 10 minutes of steady driving to prevent this. idling an engine isn't enough and won't create enough load and heat to burn off condensation within the crankcase.
That's why in the winter if I have to do a really short drive to do something where the engine never gets any heat I take the Crown Vic beater car and let 20* winter temps abuse that. LOL
And of course that engine NEVER shows any water/condensation at all and that V8 takes for ever to get warm !!!
Took the E55 out for a beating today to burn oil off the valve covers from the gasket job. I replaced the cap with a new one, and showing a little condensate but much less. Will monitor but hope this is the explanation.
Change your oil often. You don't want that moisture mixing with the oil.
Still more than I would like to see in the cylinder heds but don't know the miles on your last oil change.
