My boy and I are working on a wrecked 04 WRX. We are buying a new shortblock with associated parts (new oil cooler, pan, pickup, etc).
He has been undoing the spider web of stereo wires and such, and found a hose under the dash that leads right to a T on the Cobb bpv the guy added.
I dont think I should be running a cobb bpv of any kind with a stock rebuild and a stock tune, I wonder if that is what blew this engine in first place (has piston slap and spun rod bearing(s))
What is this hose for? I am thinking I should definately source a stock bypass valve?
