Mercedes CLS55 AMG W219, Leaking Rocker Cover Gasket (Again)

Last time I will be using gaskets from Febi Bilstein as the rocker cover started leaking again around cilinder 4. Replaced it with a Viktor Reinz gasket. If it will leak again, I will buy them from the Mercedes dealer.

Mercedes CLS55 AMG W219, Replacing The Rocker Cover Gaskets

When I replaced the spark plugs, I noticed some massive oil seepage/leaks from both the rocker covers. I bought the original Mercedes liquid sealant for the breather chambers. I already read that this would be cumbersome, and that was no lie.

But it’s all in the preparation (degrease properly!) and take your time for that, because this is not something you want to do a couple of times.

OE Mercedes sealant partnr: A003989982010

I found out that a deep 18mm socket and 1/2″ extension enabled me to use a kit gun, essentially making the job way easier! If you look closely, you will see the setup in the back of the photo.

Happy to see that all looks well under the rocker covers 🙂




Volvo S80 2.4T Thermatec Teflon Intake Spacer (PTFE)

Bought a Teflon (PTFE) intake spacer for the intake manifold from Thermatec. It will isolate the intake manifold from the warm engine, which will result in lower intake temperatures. The phenolic spacers are identical in function, only the material used is different.

Lowering the Intake Air Temperature (IAT), will result in higher power figures. A simple supporting mod, which is quite inexpensive.

Pro tip: make a small indentation in the top left corner of the spacer where the bolt would go through the spacer/gasket (where the thermostat housing is), this will make the installation a lot easier due to the restricted space in that area.
