question any of you know the size of the size of the exhaust pipe on the bottom of the EGR valve? cant seem to get at it with an adjustable wrench. do not think i can adjust the intake manifold without removing this 1st to be able to get to these clips on the back on the fuel rail. to make more room to remove? My idea is to get the pipe off shift the intake just a little to remove the darn fuel lines that they have bolted to the back of it, as if the fuel regulator bracket was not hard enuff to get the heck off. the more i work on these the more i hate the design team. Just because it works in cad does not mean you should do et. So again for clarity what size is the nut that attaches from the exhaust pipe to the egr valve? or if you have any other things i should know or how to go about this when removing the intake manifold. Thank you in advanced.
