When someone first buys a turbo Subaru they are excited to modify their new toy. Often they’ll buy a exhaust, a intake, and a aftermarket blow off valve that replaces the factory BPV. Unknown to them Subaru’s often need to be tuned after even a little change like installing a intake or in this case installing a blow off valve.

If this guy took all of two seconds to type into google”Subaru blow off valve” he could have had all the answers he ever needed. Message boards like IWSTI or Nasioc have extensive stickied threads on this exact topic from people who are experts with turbo subarus.

Now he has to deal with people trolling him and people that are as clueless as he is. After a week or two he’ll probably ignore all advice and install it anyways. Two weeks after that he’ll be asking why he engine is knocking. Said person will complain that he bought this car with a loan and doesn’t have any money to get a new engine nor has the skills to build his own.
