I have not been able to remove the pipe plug on my rear header since I got my new intake and heat kit. The front plug come out no problem, but the kit is designed for the rear one to be used.
I have used different penetrants on it and used all kinds of wrenches. It just gets worse. Aside from drilling it out, does anyone have any suggestions on how to get this plug out? Since winter has come i ahev decided to attack this issue again, since it is more noticable in the colder weather. Thanks for the advice!
