Reading posts on this service procedure and have a question, does the OM603 series engine in the 350SDL have the same service procedure ? I am in process of acquiring a 91 350SDL and am attempting to do any maintenence items that will keep this motor together . Am not familiar with MB diesels but have always been a good wrench turner/problem solver type . Have read '' extensivly " about the 350 SDL issues so I'm not going into this blindly. Thanks for any info !
