The engine started to make a rather disturbing ticking noise when cold a couple of thousand km ago. After some enquiring a lash adjuster seemed to be the culprit and the issue was put on hold since I didn’t want to do the fix roadside and it didn’t need immediate attention. After removing the valve cover one adjuster could easily be pushed down (meaning it’s broken) while the rest were rock solid. Tdoay I finished removing the camshaft and the old adjusters. Five were changed at about 210000km and aftermarket versions produced by INA, the other five are originals (also produced by INA but with a merc part number) and hence running since 290000km. Now one of the old ones gave up. I HATE THE PREVIOUS OWNER FOR NOT CHANGING ALL LASH ADJUSTERS. They are about 13€ a pop and now I have to do all the work again…

The engine without camshaft and lash adjusters and exhaust manifold which was removed because of a broken gasket.

The missing Parts. The camshaft looks amazingly good, almost no wear and tear despite running for almost 300000km. That’s what I like about Mercs…

Now I have to wait for DHL to finally deliver the new parts and then I can put it back together…
