The 300SEL 6.3 custom exhaust system - with a mishap 

So the ticking is infact excessive valve clearance - all of the adjusting ball studs are kind of stripped and turn too easily. Surprisingly no one has come up with a solution for this and naturally - they are no longer available. This engine will require valves adjusted VERY regularly at this rate.

I have a friend that has a 280 se with the m130. He had exactly the same issue. Oiler tube blocked and it completely destroyed the cam lob and rocker arm. Glad you caught it in time. I'm currently restoring and rebuilding a 1970 109 6.3. Marvelous car!!

Always think it's awesome, "young" Tim loves the older Mercedes models! I remember when I was his age when I bought my 1st MB, a 1975 240D!

Your next video should be titled “The 300SEL Rabbit Hole”. I’ve already done one for the 560SL.

Car from the era when 300SEL used to be a 6.3L beast, not modern S500 with 3 liter engines

Sounds the business, good luck with the oiling issue.

That exhaust makes me think this is going to be lowered and maybe some special wheels added too. We shall see.
