Latest update: Bimmer Clinic replaced the bearings and put everything back together. The engine is still knocking, must be something with cylinder 5. They were never able to look at the cylinder or piston without me paying more to remove the cylinder head. Can't you look at the piston while removing the crankshaft and con-rods? Well I just wasted $1800 and the engine isn't any closer to being fixed.
Now I have to figure out what my next step is...
