Hello people, my first ever post!
I have an MK5 R32 mixing coolant inside the oil-not vice versa...
Any idea if there’s a common issue or do I begin doing a head gasket with a new chain?
Thanks!

Head gasket is pretty rare on this engine, more than likely to be the oil cooler.

One thing to note that in cold ambient temperatures and if the car is used for short journeys you can get white milky deposits around the oil filler cap as the engine doesn't get earm enough to burn off the condensation. Some people mistake this for coolant mixing with the oil. If you genuinely have coolant mixing with the oil dùe to a failed oil cooler or head gasket, the coolant level will drop.

We only dry store it in our garage and start it twice a month.... hasn’t been driven more than 100 miles for the year.
Haven’t noticed much drop in coolant. I’ll probably start with oil cooler.
Thanks again

Well if that's the case, it will probably be the fact it's being started twice a month and the engine oil never gets warm enough to burn off the condensation and it's emulsifying in the oil giving the impression of coolant in the oil. My money is on there not being an issue but good luck and come back and let us know what you find.

Agree with Cuprabob.

Clean the oil cap of any emulsification, take it for a long drive. Check oil cap when you get back.

Stop starting it up, if you aren't going to drive it.

 

That's WAY worse that leaving it for months without starting. Creates moisture and acids in the oil that start corroding things.
