Hi, first of all 1998 Expedition 5.4L Eddie Bauer 4 X 2, I have the 90 Deg Elbow that goes in the intake part # KM 4528 broke inside the manifold , my problem is: I notice theres a remaining part of the pipe like welded inside the intake manifold where's the new pipe goes, i try a lot of times to take out without results, theres no space to work, the only choice is dismount the intake manifold? I just want to know if someone have this problem before any advice going to be apreciate. TX.
