New project !
Are weeks that I'm looking to install an oil catch can to collect the oil vapors that are recirculated to the motor intake and that they cause one of the most know problem with these direct injection motors: the large amounts of carbon build up on the intake valves.
I bought already a baffled catch can like this (Miscimoto clone):
but going on with my researches I found out that the bronze filter and the design of the inlet/outlet are to restrictive and could cause the crankcase pressure increase and cause oil leaks.
So in the end I found the Provent 200 mabe by Mann-Hummel that looks the best option. It is bigger (a lot bigger) than the regular catch can but it has an overpressure security valve and the inlet and outlet are 25mm in diameter so the same diameter as the inlet on the turbo intake conduct and the outlet on the rocker cover. The 200 is designed for big diesel engines. There is also a smaller version (Provent 100).
here how it is working:
The original one is expensive but the Chinese clone not .
Some other video that I found interesting:
The only issue I can see is the space on the engine compartment, but I was already thinking to remove some "plastic" (original filter box and all the air conducts) installing a direct intake like the Forge
but with a BMC CDA filter
( Just to stay on the same theme with the carbon roof and mirrors covers )
The Provent 200 will replace the right PCV hose and, now that I have already the smaller oil catch, the "Miscimoto", I will use it on the rear PCV hose instead of do the rear PCV delete (other long story to discuss ).
Question:
Regarding the direct air intake, anyone know if this can cause some engine fault code on the RCZ? I read some comment but regarding other cars. I don't want drive with the Check engine light on .
