Picked this up with the motor knocking. Used to Honda motors so wanted to ask a few quick questions. Pending theres no damage to the journals on the crank, is a standard set of bearings suitable? Honda motors have markings on the rod that correlate to a certain size. Didnt know how this worked in audi's. Also, seems to be sufficient oil but could have been added later after the knocking. Are there certain components or areas that are common oil restrictions? I dont want to just throw bearings in if oil is being held up somewhere. Thanks in advance!
