N55 Engine Replacement

Hey Guys,

I have a 2011 E70 and the engine is toast at 128k miles. It failed while driving. It had one previous owner and had been well maintained so I am not sure what happened. The car shifted to Neutral and RPMs dropped to zero when it failed. I got it to a dealership and the engine was seized. Will not turn.

Anyways...I have an N55 with 75k miles that I am going to put into the car. My questions is: should I take any preventative measures with the donor engine before having it installed? Should I replace the road bearings and if so, what would you recommend?

I appreciate any advice and input.

Thank you!
