Breather system delete
Can some one post the link (if there is one) or a write up of how to remove the PVC garbage and where to install a catch can. Cars starting to run worse and im sick of replacing hoses and the breather system is just gonna be switched over to the little filter on the valve cover. Also if the PVC system is removed will I get a CEL or anything? Im hoping this damn oil gets out of my system too.
Cars doing random backfires now too. ugh. damn you car.

Why he rips out the SAI I am unsure of. The n249 however makes sense and ill be sure to set mine on fire and **** on it. Why he took the Evap out however is 100% beyond me. I know that will throw a code and here in NY they Wont pass your car if theres EVAP parts missing.

SAI I beleive helps warm up the Catalytic on cold starts and lowers emissions.
N249 tells the DV when to open and close I also beleive.
PCV Is there to keep the crankcase air as clean as possible in order to keep sludge and nasty deposits from forming internally. but when it FAILS like mine it just makes your cars exhaust smell like **** and clogs EVERYTHING -_-

PCV stands for positive crankcase ventilation
Basically, theres always gonna be a little blowby, and expanding gasses from the car warming up and whatnot, that pressure needs somewhere to go, so theres a check valve that will let gasses/vapors out of the crankcase, but not allow debris back in.
Why's it full of oil? Because its doing it job, and venting crankcase pressure. Thats why if you remove it, you put a small filter on the line, keeps garbage from getting in and contaminating your oil.
EVAP is evaporative emmissions, basically gas fumes. Tree huggers don't want you harming the environment, so the fuel system is a closed system, fumes shouldn't be escaping to open air. The charcoal canister collects those fumes, theres some other crap involved too, but I don't really want to get into it that much.

You just get straight up vac signal controlling the DV like it should. The N249 can open/close your DV to control boost how the ECU likes. Usually that makes all kindsa goofy part throttle boost issues.
