My wife's 2002 Montero Sport, 4wd 3.0 ES, 122,000 miles, turned up with the crankshaft pulley bolt sheared off, leaving part of it in the crankshaft. My mechanic advises a used or rebuilt engine (not a service he provides). Though we love the overall sturdiness of the car and its surefootedness in snow, I am inclined to let it go rather than sink about 3k into it. Advice?

 

$3K for pulling broken bolt out of crankshaft? Wow.
Unless the engine is really damaged like valve rods are bent etc.
