Hello to you all in the forum, I am trying to track down a fantastic BMW repair shop in the northwest. I have a BMW 550 I sport that Scott problems with the rings and I have found an engine with 9000 miles on it and I wanna have the engine swapped out but I want it done by a very reputable repair shop dealerships. Won’t touch these cars and put a new engine in it. Does anybody have a recommendation I’m in Portland Oregon

 

You can check bimrs.org as a start. Looks like there are two listed, of which one works exclusively on BMWs: Pacific Motorsports.

Good luck.
