ON this engine up to july 1986 production this is a "normal(common)" condition!(high mileage) MB didn't design the timing chain to get enougn lubrication until 7/86. THEY added a chain oil spray nozzle under the front cover to combat this problem. & then in 1/88 they started using a double-row timing chain!! THIS can be fixed but is somewhat costly, $400 for parts & 12 hrs of labor.
