    Well I had a change to go out and look at the engine bay more clearly. Yeah looks like its a head gasket leak. There is almost no coolant left in the tank.

    That was obvious from your symptoms. Now it's so clear a blind man could see it.

    The question is how long do you want to drive it? Dump the car as is? Quick flip to pass on the hot potato? Low cost replacement JDM with some small risk? Or a top quality rebuilt that will go 150,000 miles?

    Also factor in that hybrid battery.

    Hopefully the previous owner didn't dump a 'stop leak' product into the coolant. If they did a used motor is just the beginning of your repair journey.
