In the tightly cowled engine compartment of an E/A-B aircraft, exhaust systems can do unseen damage over time unless care is taken to protect various components. In this case, the intake tube hose on a Lycoming engine shows severe signs of overheating due to its proximity to the exhaust system. When touched, it was very brittle and started flaking apart. Left unchecked, it will eventually cause an intake leak and the cylinder will run lean.
