RADIUM ENGINEERING PCV CATCH CAN + SICO DEVELOPMENTS PCV PLATE INSTALL! | FOCUS RS

I install the PCV side oil catch can system for Ford Focus RS MK3 from Radium Engineering AND the SiCo Developments PCV plate to perfectly compliment it!
I go over the parts as well as the steps required to install this system which is not just great looking / aesthetically pleasing but also beautifully machined, light weight and all feels very high quality!
The basic idea behind any oil catch can is to avoid unwanted carbon build up on valves from air being vented into the intake that has vaporised oil in it (blow by). This is an issue if you have or plan to upgrade your Focus RS for more power but is also equally applicable if you are stock!
In standard form, the PCV (positive crankcase ventilation) vents oily air directly into the rear of the intake manifold. This then gets sucked through the intake manifold, through the inlet ports and into the engine where it is combined with the normal air and fuel and so gets burned. This isn't ideal and in particular with the CCV side compared the PCV side, this oily air can clog the intercooler. This makes it less efficient at providing nicely cooled air which can cause a drop in performance.
It really does look sweet in the engine bay, being just view-able behind the intake beside the battery cover!
Installation was pretty smooth sailing - experience from previously doing the CCV side catch can from Radium Engineering definitely helped! - although some points to note are the need for fairly large wrenches/spanners and a big socket (29mm or 1 1/8 inches) to torque the top banjo bolt and also the rubber piping, although excellent quality being flame resistant etc. is a tight fit onto the very aggressive barbs for all the connections so softening them up with a heat gun is very much recommended!
Implementing some degree of control of the PCV gasses whether it be one or both of the PCV breather plate and PCV catch can is in general simply a good idea to look after the engine as well as having the added benefit of boosting octane due to reduced oil in the fuel/air mixture!
SiCo Developments says about their PCV plate:
The plate is designed in house and manufactured from 6061 billet aluminium and finished in a black hard anodised finish. Internally the plate features increased baffling to reduce oil vapours leaving the PCV.
Radium Engineering says about the PCV catch can:
When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience "metered" vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapour, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. Note: Because the Radium catch cans are pressure sealed, they are great for this boosted application so intake manifold connection is permitted.
