Well my EGR tube is rusted and has a hole in it. Its driving me nuts so i'm going to replace it. Is it hard to get off, looks like its kind of in a painful place to remove it. Just the tube is screwed up so do i need to get additional parts or can i just replace that? Anything i can do, like spray bolts or anything that will make this easier? Thanks in advance

 

I replaced mine this past summer, It's easy, just a pain trying to get to the mounting bolts,, if your egr is that bad you may want to look at getting a new sensor as well.

 

spray some rust penetrant/penetratin oil on it and let it soak in for a few min and it will come off

 

how much does the sensor cost?
