Timing Chain is on other side of engine so would expect to be louder over there. Crankshaft bearing knock should be louder underneath car. Wondering if it is connecting rod bearing. Maybe piston slap. I looked at exploded view under Engine on eSaabparts to see if it could possibly be balance shaft chain but it looks to be on other side of engine also. Could noise be coming from valve train?
