4 cyl or V6?
Hard to say how long it will last with only 2 of the 3 mounting bolts installed. Most likely the bolt broke due to the threads being seized so the reminants will not come out easily. Best solution would be to have the broken bolt drilled out and replaced.
I expect you can drive it for some time especially if you go easy on the gas. Maybe someone else here on the forum has had a similar experience and can advise.
