To determine if the engine knock in this old diesel is internal in the engine or just a loud fuel injector, Kent will perform a live diesel purge. He will explain how the process is done and why it works so well to help diagnose diesel engine knocking and pinging noises. You will get to see and hear first hand what he discovers. This will apply to almost all Mercedes diesels from the 1950's up to 1999 including the This includes the 170D 180D 190D 200D 220D 240D 300D 300CD 300TD 300SD 300SDL 350SD 350SDL and E300D.Part 1: http://youtu.be/BSTtMl9HCDcPart 2: http://youtu.be/Pe_3nbCARLAPart 3: http://youtu.be/hvRlRj06A0sIn Part 1 Kent did a quick walk around of the wagon to see if it was worth restoring for the owner. In Part 2 Kent attempted to start the engine by just charging the battery and not doing anything else. This proved to be a good preliminary test of the internal health of the engine. You will be amazed at the results. Kent then goes inside the shop to discuss some of the challenges associated with "waking up an old diesel engine" that has sat idle for a long time.
