Subaru Jim Maple Ridge Posted September 29, 2009 Share Posted September 29, 2009 99 OBW 2.5 DOHC OBDII called up egr flow. Egr was dirty but not plugged, but tube is. Any simple, easy magic tricks, or just find the time to take it all apart and clean it properly? Thx Jim Link to comment Share on other sites More sharing options...
lmdew Posted September 29, 2009 Share Posted September 29, 2009 PB Blaster the nuts, let it soak. I like to use tubing wrenches to break thing loose. The plug could be at the head as well. Yep, pretty much have to pull it apart to clean it. Link to comment Share on other sites More sharing options...
Fairtax4me Posted September 29, 2009 Share Posted September 29, 2009 You'll need to take the tube off and clean it out. I use a bottle brush for stuff like that. If you have a bucket of parts dip, dunk it in there and let it sit for a night. Link to comment Share on other sites More sharing options...
