Have a 2002 4.6 (110K+) - The hose fitting on the back of the back of the intake broke when a tune up was being done. The guy advised you have to move the hose to access the coil pack, and when he moved the hose the intake broke where the hose attached. The guy doing the tune up showed me the parts, oIt looked real brittle & broke into several parts inside the hose, and the guy said this happens due to heat and coolant after time & he did nothing wrong, but I will have to replace the intake. Does this sound like he is on the up & up? The shop comes recommended
