Yeah far fetched. Lol. But maybe worth a try. If you can break that stuff up with a solvent, with time they may flush out. On a POS, I would try it before they fully collapse. Some people have had success. But this is outside Mercedes we're talking here.

But they say that hole in the lifter for oil to come in is the most precisely machined part of a motor.

Lots of different motors out there. This is DOHC with similar design, 15 on the book. But in order to get the belt off, to get the cams out, you have to remove the crank pully. Can of worms. Then here's the vvt system.

Granted, 15 hours on the book is probably a lot less in real life. Still not fun.

With any lifter, the only difference you will find is one or two springs inside. Always one for the check valve, but there may be a secondary to lift it up before pressure builds.

Unless you get into exotics. Then who knows.


All and all, I think I would replace if possible. Unless it's a junker. Then I try a flush, until it fully collapses.

Just oil weights and types can quiet them down.

I would rather adjust valves. Lol. I don't like them. Not to mention that you get a lower redline with hydraulics, and if you go over, you are going to over pump it. If you don't shut it down, you can interface the valves into the head

When they are sunk in with pushrods, they make a tool to extract them. It can be easy, on most motors. If I had a jeep that needed engine work I would pull it and put something else in. Jk.
