Stopped by my MB/BMW indy shop the other day to purchase a small part. They had a late model BMW up on the lift with the engine out. The engine block was on an engine stand completely stripped down. They told me it needed a timing chain and that you have to take it down to the bare block to accomplish this. It was the 4.0 turbo v-8. They said it would be at least $6k. The car belonged to a used car lot and appeared to have a junkyard engine because there were writings on the engine. The car lot wanted it fixed. I figure they must have got the car for next to nothing, tried to put a junk yard engine that had a bad timing chain. I asked about the oil used etc but they didn't have any history on it. Why would a late model BMW v-8 need a timing chain or new engine?
