1-3-2-4 Posted January 29, 2013 Author Share Posted January 29, 2013 yep 17mm and I might need to use heat on it.. used a flare wrench.. used channel locks to turn.. still wont move.. however having said that trying to get the pipe off the head would be a bit odd.

ocei77 Posted January 29, 2013 Share Posted January 29, 2013 Remove the EGR valve and gasket. Use two nuts. The 12's that came off will work. Use a wrench on the inner jam nut and you can turn the stud out. This will give you room to use either vise grips or a small pipe wrench. PB the copper pipe well . This won't strip the nut and gives you the oomph to pop it loose. Heat won't hurt, but I had to resort to the above method to get mine off. Didn't have to remove the bottom one in my sitaution, but I'll cross that bridge when I get to it. O. Link to comment Share on other sites More sharing options...
