If it ran without water and the pistons expanded from the heat so much as to score the cylinders, the engine is toast. Does it turn over? If so, do a compression test.My main concern right now is if the engine will "un-seize". Thankfully there are only a few streaks of "milkiness" in the oil from what I can see, so I hope the damage isn't catastrophic.
Should be the repair shops responsibility.........is this car out of the 5yr/100k powertrain coverage?2013 Cruze LTZ
I took the car in the other day to have the water pump gasket replaced. Well, apparently the cap for the coolant reservoir wasn't put back, and it over heated on the freeway today. From the time it told me the AC was being turned off to the time I had the car pulled over and turned off, it was only about 30 seconds.
I refilled the water and tried to start it, but it won't start. I had it towed home, and see the oil is milky. Great... a blown head gasket. I will be changing it on my own, but I'm wondering if the car is "fail-safing" itself, or if it is seized. How do I tell? If it is in fact seized, will replacing the head gasket and making sure nothing is warped "unseize" it?
Remove the plugs and try to crank it......stand clear as water may come shooting out of the plug holes.
If it blows water and cranks then, at minimum, the head gasket has failed.
Once removed, the head should be sent to a machine shop to check for warpage and, if it is within spec. then a gasket should be all you need.
And, of course, a oil change since some coolant is intermixed.
I tend to think of a head gasket as a 'fuse' of sorts......often it fails before any other significant damage occurs.
Looks like droplets of dex cool (coolant) to me. Wet plugs, fuel or water, won't spark.....the fluid provides a ground path.It shot mostly out of the middle 2 plugs, and here's what it looks like.
No white smoke at all, actually. I am draining the oil as we speak and have the plugs open to hopefully help evaporate whatever's in there. I've also found all the parts I need available for immediate pick up only a couple miles away.Looks like droplets of dex cool (coolant) to me.

Based on your photo and cyls 2 and 3 being affected, I'm lining up towards a head gasket failure. Four bangers typically blow between the center cylinders.
Did you get much white smoke when you started it on the road?
Minimize running it though......coolant will kill the catalyst.
