trying to remove the heads on an 04 D2. Can’t get the damn secondary air injectors off. If I try to loosen the metal lines, the whole connector just turns. I’ve tried everything I can think of. Anyone have this issue before?
Once you unbolt the exhaust manifolds (both sides) and let them drop out of the way...you can easily get a 18mm wrench in there to hold the head fitting. Sometimes, a small amount of heat helps too.
