Mysterious Oil Consumption? Change your PCV Valve! in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX Posted June 15, 2008 I removed my OE PVC valve (EJ22 NA) and it had a little sludge in it. (it still rattled, however) I washed it out with brake cleaner and re-installed it. Is it really necessary to replace a PVC valve if one can clean it instead? What would be the advantage of replacement?
