Egr

[slick]

Is there any pictures of the egr passages out there, I want to clean the passage out and was wondering how difficult it is and could any beepbeepbeepbeep fall into a bad spot and do damage. I heard of the passages becoming so clogged the manifold needed to be replaced. also where does the passages start and end

this is a very good question....Marc?

Usually while I have the faulty egr out I take a round wire brush and clean the hole. If it was as bad as you said which I've never seen you could just pull the intake off and clean it.

I agree with Jon....If you have majorly plugged EGR ports, it needs the intake removed to clean to prevent stuff from getting to the cylenders. If its just right at the EGR valve area, you can probably get by with a shopvac, but if its thicker than lets say 1/8 inch of crud, you really should take the intake out to clean it. I actually have had two, one customer pay and one warranty with approx 90k on it that i had to replace the intake because the carbon build up in the EGR ports was so think it couldnt be cleaned....
