Got to the rod bearings on my 217K mile X5 4.6is, they are in awful shape lol... pictures don't show how bad they really are. The first cylinder was so loose that you could jiggle the connecting rod by hand and hear the slapping of the rod against the bearing. Whats weird is that this car didn't make any noise until maybe 10 miles ago at which point it was babied home and no way did all that wear happen in that time

The crank looked great except the cylinder 1 (which had that chewed up bearing). So engine will be coming out, crank removed and machined then oversized bearings installed. The entire top end of the engine is already new except head gaskets, so since I have to take the engine out I'm going to take this time to replace the piston rings and refresh the lower part of the engine - already had most everything I needed anyways
