I recently purchased a well cared for '84 300D with 171K from an attorney and yesterday went to the MB dealer to pick up an oil filter and fuel filter. While there, I asked the service manager how much they charged to adjust valves and he responded that they do not work on that old of a diesel, which surprised me. He said the older diesels are too much different than the new ones. He then told me not to worry about adjusting valves unless they rattled. I had heard somewhere that the valves should rountinely be adjusted as preventative maintenance. Who is right??
