lexus400 Posted November 16, 2005 Share Posted November 16, 2005 I removed what I think is the EGR valve assembly - (5) 10mm nuts but I don't see what I can clean ? The manual says "check valve for sticking and heavy carbon build up". There are two tubes but they look ok... not clogged. I removed the whole thing and I think the valve is the round piece with the single vac line attached. If so, how does that come off ? I don't see any screws or bolts that attach it to the cast iron piece ? It's next to the vac modulator. thanks, Bob P.S. - I was getting an EGR "restricted" code a few months ago and now it says "excessive" so I assume my problem is the EGR valve.
