Stock egr stuck!
So i purchased a header and flex. the header has had the flange cut so i talked to a exhaust buddy and he said if i put the header on he would welt an ORP in theory from the header to the new flex....my problem is i can get every bolt off except the one from the egr to the cat....i tried wd-40 and pb blaster still stuck on there...any other tips to get it off without pulling it off the intake? my new headers have an egr bung thus i dont want to remove it for tune purposes. thanks :)
