Remember only $8k is for the replacement motor the other $8k is labor and tax. Can you rebuild that BMW 3.0l for less than $8K? IDK but I think it is going to be close.

It won’t be only a crank, the block will need to be completely disassembled and cleaned out of all metal contamination. You might try reusing the pistons as is with out replacing rings but it was burning oil and you don’t know why so that is a bad idea. At least one rod is needing resizing or replacement, but you should check all 6 to be sure. You can’t have metal go through the motor and not replace the oil pump or rather it is very unwise. So the parts cost alone will be difficult.
