Finished another round of mods & maintenance for the E46.. I think I run out of ideas/mods to do...

Decided to install the Mann-Provent 200 Oil separator to cleanup oil vapors passing the M56 cover.
Custom bracket and install position ideal next to washer tank.

Repurposed an old ATF reservoir as the most OEM-look catch for the provent drain system. I didn't feel like routing hoses around engine to drain back to dipstick tube or even want to drain water back into the engine

Visited the jewelry shop (dealership) and got myself 2x new rear bumper support bolts (€18 each). Old ones after 20 years were half the size from rust and didn't want to risk having them snap.

Also had the manifold machined flat at my local machinist for max sealing. All parts sealed with Loctite ultra performance grey rtv.

I went for the smallest supercharger pulley possible, 58mm for max boost. 16psi from 3500rpm. not bad. New tune of course.

Checking in on this…

How is the Provent 200 holding up? I have a (genuine MANN-HUMMEL) Provent 200 on order.

Did you modify the internal spring or pressure regulator or running it out of box?
