The key to getting a used engine installed, is that some junkyards, (usually at slightly higher price), will guarantee a used engine for 90 days. Not only that, if the engine is no good, they will provide another engine and reimburse the shop for doing another swap. Since it's always a toss up on any used motor, and it's about 12-14 hours labor to do the swap, you want the labor guaranteed as well.

So if the BMW dealer offers to provide an engine, will they guarantee it for a certain period, INCLUDING labor? 90 days is plenty to know if the motor is good, and if you choose, get you onto an aftermarket warranty.
