Coolant in oil help

Hello,

My S6 has been sitting in my driveway stationnary (has maybe been started 2-3 times) since end of november while chasing an issue that ended being just a f*cking blown fuse SMH.

Ive noticed during this chase that my oil got milky, and my coolant level dropped to the point where my car warns me when I start accessory even tho I only started the car a couple of times.

Ive seen that the most probable cause is the oil cooler? I dont think there is oil in my coolant, just coolant in my oil, so is there a way to check if its the cooler and not the timing cover o-rings that failed?

Thanks

I pressure tested the coolant side of mine while I had the engine out to make sure it held pressure.

I think there would be oil in the coolant too if it was the cooler with the pressure differences, I guess if the car hasn’t run as much the oil in coolant wouldn’t be as noticeable. The only way I can think of to know for sure is to pull it and test. Maybe do a pressure test on the coolant and listen for any leaks?

Also my leak was the radiator. Did the oil cooler o rings while it was off too, that was aggravating and couldn’t even get the hoses off of it.IMG_20260228_181223338_HDR
