head gasket S40-V40 2006

I looked at a 2006 S40 w/113K yesterday and after starting the engine I went to open the overly tight coolant reservoir.
It hissed and spewed immediately upon loosening. The surge of pressure into the bottle was as strong as I've ever seen.
The smell was of raw exhaust. It brought teas to my eyes.

Clearly the head gasket was shot.

Either a design flaw or overheating caused this condition. Please take note of this inspection step.

    I'm not sure I would dismiss this as a blown head gasket.

    Isn't the cap on the overflow tank a "pressure" style cap?
    Meaning that the overflow tank is normally under pressure when the engine is running.
    I don't think it is unusual for coolant to spew out of a hot engine when the radiator cap is removed. Many have been burned by doing that.

      Yes to what you said but not this time....I had just started the engine and it was still cool.

      Happy New Year

    That's OK, you wouldn't want an S40 anyway. Too small.
    As for the engine, sounds like PO didn't know how to add oil.

    Keeping it running is better than buying new
