Thermostat failed on the highway and by the time we could pull over the car heated and i seem to have blown my piston rings.
The car is consuming oil and blowing smoke on acceleration, at idle ie behaves like a puppy.
My mechanic suggests I sell the car, but i think i should get a fair idea of the engine rebuild. If anyone has done this before or can tell me about this- what this entails and the effort, reward and risk that go with it, I would be obliged.[/quote]

Any idea on repair, turbo costs, labour.... salvage parts stores?

OK, as far as I remember, the 2018 has the updated thermostat assembly, when you say failure of thermostat, there are two potential failures, one is the assembly failure and coolant pours out of the failed hose connection. The second one is the actual failure of the the thermostat valve itself. Usually, the thermostat valves are designed to fail open, so the coolant will flow, but the car will take longer to warm itself.
Which of these failure did you get? Was there a engine hot light ''ON" in the dash? How long did you drive with that light on?
Secondly, you are talking about turbo consuming oil. This is a more possible scenario. The turbo seals may have gone bad. Unfortunately, turbo repair is not so common and folks usually push for replacement as it is more money and easier to do than a repair. If your routine has turbo getting spooled up before the oil getting warm, then it may have more chance of failure.
Thirdly, your oil has to go somewhere. If it is going via the turbo to the inlet side, and then getting burned, you also need to clean the egr and the inlet manifold, intercooler as all of these components especially, the intercooler will be filled with oil. If the oil is getting burned via the piston rings , the blowby would be extreme. You can check blowby using any of the tutorials in youtube. If the consumption is as you say it is for the fault of piston rings, then expect a huge amount of blowby. Remember, small amount of blowby is ok. Check on a good running engine if in doubt.
