Hello Everyone,My trusty 83 240D is making crackling knocking noises when I first start it up in the morning or when it has had a chance to cool off for a while. The sound is like the "spark-knock" sound that a gasoline engine can make. When the engine warms up the sound goes away.
Anyone know what is causing this? Is it damaging my engine? Thanks, John Ingram 83 240D 243K Baltimore
