My 2015 RXP is mixing oil with water

I removed the intercooler hose & it looks like milk inside. Someone told me it could be a leak in the intercooler

You can pressure test the intercooler with air using around 20 psi, but that does look like the problem. Change the plugs also, change the oil by sucking all the oil out then start it up for 30 seconds and finish drawing all the rest out. Not winterizing properly is a major problem with water intercooled machines.
