@18:56, I didn't know about the external chain tensioner. Is it a serviceable piece? I did one on a 2004 Benz C240 2.6L. No info or video was available. All info lead to the newer 2.6L version. I created a short replacement video. It had over 500 hits on YouTube in one day! It was easy. Set timing to 40 degrees. Unbolt the tensioner. Verify the chain was loose . Install the new tensioner and check for oil leaks. Car ran a lot better.
Edit: One video commentor!
