Oil didn't appear milky but I will check further when I get home. Luckily I have an extra vehicle so I won't drive it except to put on a trailer. My son said it smelled like "maple syrup" when they got home. The steam/smoke rising out of the oil filler neck seems strange. Steam/smoke also coming from area just above spark plugs on front of engine. All of this prior to temp gauge registering even normal range.
