Mercedes CLS55 AMG W219, Replacing the Supercharger Pulley Bearing (Nachi)

I decided to replace the supercharger pulley bearing with a fresh new Japan made Nachi bearing. One of the easiest way is the hot/cold method, where you heat up the pulley and freeze the bearing itself. This results in the bearing sliding into the pulley with relative ease.

I could’ve also used my workshop press, but I didn’t want to force it in. I followed this guide for it:

Mini Cooper S R53 JCW – New Downstream O2 Sensor

Replaced the O2 sensor with a fresh new one from Vemo. I totally forgot that the Mini Cooper has 2x O2 sensors 🙂 Don’t forget that O2 sensors have a replacement interval which is usually somewhere between 160.000 – 250.000 km.

Update per 01-01-2021: I replaced the Vemo with a new O2 sensor from Magneti Marelli. The Vemo already started giving issues after a short while. It will be the last time that I will be using Vemo.

Volvo S80 2.4T New Serpentine Belt Tensioner

Finally fitted a new serpentine belt tensioner, needed to wait for a Torx T60 bit to be able to take the tension of when you fit the serpentine belt.

Mini Cooper S R53 JCW Heatwrapped Stainless Exhaust

I heatwrapped the new stainless steel Gravity Performance catback exhaust. Unfortunately I ran out of titanium heatwrap, so I ordered some more (black) and finished the job.

It will help with scavenging and is a supporting mod for extracting more horsepower and torque from the Mini.

Volvo S80 2.4T Plastidipped Grill

I wanted a cleaner look for the front grill and decided to use plastidip instead of the carbon wrap. It came out great and suits the black S80 very well.

I used Motip Removable Coating instead of classic Plastidip and it holds very well till this day.

Also repainted the front trim with bumperspray (which didn’t hold by the way).

Volvo S80 2.4T New Engine Mounts

When you have an older car, always think about replacing the engine mounts. They are almost always made of rubber, which becomes brittle over time due to aging/drying out.

I replaced all the engine mounts, which tightens up handling and improves performance and reduces strain on components like the exhaust, as the engine swivels way less. Highly recommended!

Volvo S80 2.4T Diffuser

Added 2 diffusers to the rear bumper of the S80. Looks very nice and makes the S80 less of a Old Man car haha 🙂

Volvo S80 2.4T Replacing the Car Battery

Replaced the old battery with a fresh new battery. Decided to mount a larger type, as the S80 has room for it.

See the big difference in size, which should account for a little bit more performance and safety as it has a lot more power.

Volvo S80 2.4T PCV DIY Repair / Service

Repaired / cleaned the PCV circuit as I saw a lot of oil in the pressure circuit (also see my previous post: https://www.ducked.nl/blog-entries/volvo-s80-2-4t-dirty-clean-turbo-coldside/ ).

Did a little research and the PCV system is almost always the culprit for such issues.

Decided to buy a complete system although ended up cleaning the existing system and only replacing the oil seperator. The tubing was quite some work, I will save that for another time.

Volvo S80 2.4T Dirty / Clean Turbo Coldside

Replaced the air filter and the turbo intake pipe. Please note that a dirty intake might also point out a badly functioning PCV system!

The intake pipe was upgraded to a blue Do88.se / Do88 silicone intake pipe, which is a fair bit larger, but also deletes some bottlenecks from the original part (like the narrowing bend on the bottom and the “harmonica”).

Gives a little bit more power from the butt dyno and noticed more intake growl (which is a good thing) 🙂
