Thanks! I really hate installing the cyclonic oil separator to the oil return pipe when renewing the vacuum hoses. Zero room to work with while trying to clamp it.Make no apologies! You're blazing the trail. I had been through the thought process of doing a catch can install, but ultimately came to the conclusion that, when working correctly, the OEM PCV and cyclonic oil separator work very well. It's just that when they fail, they cause a whole host of other issues. So I'm particularly interested to see how you mount it and what kind of results you get. It will be really nice to have an intake manifold that will remain clean and virtually oil free!
On the electric fan, I had played with this on my BMW 8 series, but ultimately also decided to revert to the fan clutch mainly because it was too laborious to mount the fan at the lip of the shroud vs on the radiator. I like how you did it!
Yeah the crankcase pressure has to be managed. I also wonder how VF accomplishes that. I can see a lot of valve cover gaskets and other seals leaking prematurely. As much as I would like doing away with the pcv valve, I don't have the luxury for trials and expensive repairs lolAhhh so you are retaining the factory PCV valve (on the back of the intake manifold), but just replacing the cyclonic oil separator, I really like that as a compromise, and on a side note I also like the look of the braided tubing you're using too.
On the VF Engineering supercharger kits for the M62TUs, they actually include a blanking plate that deletes the PCV valve on the rear of the intake manifold, which also deletes the oil separator. I've always wondered how they manage the crankcase pressures when they do such a thing...
Also, I noticed you did the smart thing and changed out those annoying tox bolts on the back, kudos. I've had several of those bolts so stuck, that even with the intake manifold removed from the car and on the bench, I haven't been able to remove them without breaking out the bolt extractors.
