cbj Posted July 31, 2010 Share Posted July 31, 2010 Hello all, Obviously new to the forum, figured it was time to join. I currently have a 1998 Legacy GT-B (EJ20H backed by 4sp auto). Lately, it is beginning to honk a bit when I lift the throttle. In my old VW days (1.8T) that was an indication of a failing bypass valve. If this is true for Subarus as well I was wondering if someone could recommend a source for finding a replacement. Aftermarket or stock is fine and I can order no problem from the US so it doesn't need to be a supplier that will ship internationally.

Olnick Posted July 31, 2010 Share Posted July 31, 2010 Welcome to USMB, Chris (first time I've ever said that to someone in Namibia!!! ) I know nothing about turbos but I'm sure those who do will jump in here. Link to comment Share on other sites More sharing options...
Legacy777 Posted August 2, 2010 Share Posted August 2, 2010 Welcome. Can you describe the "honk" a little more. I think you're probably on target for it being the bypass valve. You can remove it and blow through it and see if it leaks. I'd recommend staying with a full recirculating bypass valve over a vent to atmosphere valve.
