    Maybe it is a 13 speed and you have a bad spitter valve or bad switch in the shifter handle.

    Does sound like you might have a bad head gasket, or cracked head, or something serious.

    Not to scare you, but very rarely does a just a head gasket go bad. Usually something cause it like a cracked head or liner.

    This is why I do all my own work.

    I'd bet on a head gasket. This means a liner sunk. The $2700 will not include the time or labor to cut the counter bores and shim the liners back up.
