I was planning on upgrading my exhaust hear soon. With that I'm removing the twin scroll, stock wastegate, cats, airpump and the ACV. When I do this it is my understanding that all the solinoids on the drivers side can be removed. I already have the fuel pressure solinoid removed due to my dumbass roomate breaking it. The question comes from the *pcv* operation. I think there is a solinoid or something with a check valve. Can I just run a line from the vent to a catch can or is that just going to blow unbelievable amounts of oil. Thanks.
