Camelwagon Posted August 25, 2005 Share Posted August 25, 2005 IS there a way to clean the EGR valve? And how? Gotta take it out to do it? Thanks. Link to comment Share on other sites More sharing options...
edrach Posted August 25, 2005 Share Posted August 25, 2005 Yes, you will have to take it out. Link to comment Share on other sites More sharing options...
KStretch55 Posted August 25, 2005 Share Posted August 25, 2005 Book says to rap it with a soft mallet to knock particulate loose from the valve seat area. I've used small wire brushes, wire and compressed air to clean the passages. Link to comment Share on other sites More sharing options...
Camelwagon Posted August 25, 2005 Author Share Posted August 25, 2005 Can you use water and then let it dry off? Link to comment Share on other sites More sharing options...
Subi81 Posted August 25, 2005 Share Posted August 25, 2005 Water will probably not get off the hard carbon deposits. I think some manual cleaning will be needed. Link to comment Share on other sites More sharing options...
Hank Roberts Posted August 25, 2005 Share Posted August 25, 2005 Also look at the ports in the engine from which gas comes to the valve and goes back to the combustion chamber when the valve is open. On my GL when I bought it, turned out that both ports were packed solid with carbon. It took 2 mechanics a good while to clean the engine out with solvent and elbow grease. Apparently this may have happened because the PCV valve tube was crimped shut for a year. From my growing list titled: Things I wish I'd known _before_ buying the first Subaru. 1 Link to comment Share on other sites More sharing options...
