It's pretty straightforward. I did mine in about 10 minutes.
I did add a piece of high density sticky foam to one of the radiator hoses where the bottom of the OCC just rubs it to avoid any possible damage to the hose. I'm planning to remove and empty / clean it this weekend so ill get a few pics. |

I like my stupid OEM burbles. But I can live without them if they are causing unnecessary wear. |

TLDR: About 1/8th a cup of fluid was collected after 1 month of driving. That seems like a considerable amount for such a short time. https://www.youtube.com/watch?v=ueQKh5ORo3g |

A few things to consider with catch cans.
1 - If you daily drive in the winter, there is some risk that the liquid freezes which clogs lines and causes major issues. This happened to me on my VW Golf R. Standing in freezing temps with a blower dryer was not fun. 2 - If your driving patterns are more short trips where the engine does not run at full temp long enough to cause condensate to evaporate, there will likely be more fluid in the can. 3 - There is a lot of debate about whether or not catch cans have any impact on carbon build up on valves in direct injected engines. The location the catch cans typically connect negates much benefit from the deposits on the valves. What it will do is reduce the liquid seen in the above video and keep it from being in the oil. |

Overrun isn't burbles, it's the term for rolling with your foot OFF the gas. When an engine is being turned by the moving car then a vacuum is generated in the inlet manifold and the crankcase fumes then are drawn directly into the inlet manifold without passing through the inlet/turbo/intercooler route. |

Normally all that would be sucked back into the inlet tract, through the turbo and intercooler and then the carbon in it burns onto the back of the hot valves. All the carbon on valves comes from crank case vapour, nowhere else. The liquid in an OCC if the OCC wasnt fitted would never get in the oil, not possible, it would just get passed through the intake as above. |

Installed my BMS catch can today. I have run catch cans on most of my cars over the years.

I removed the carbon strut brace in order to install BMC drop in filters and do a charcoal filter delete. The bolts use low tightening torque and are reusable.

I didn't find it necessary to take the strut brace off.
Just slipped the OCC under it and attach the bracket afterwards. Same reverse for removal. |

Well, I just spent 20mins trying to pry off that damn PCV hose from the engine without any success. I know there are tabs you gotta use a screw driver to press as you wiggle the hose off but there are 5 tabs all around and there's also that plastic thing onto which the engine cover sits on that's in the way and makes it super hard to get to the tabs on one side. Any advice?
UPDATE: went at it again with more force and managed to get the damn thing off but in the process some of the small tabs broke but I don't believe there is another way around this. I don't think those smaller tabs are needed anyways. Here's the pic of the small tab I'm talking about: |
