Narrative:

Crew chief was reviewing the logbook for [the] aircraft. He pointed out to me that this aircraft has the same issue I discovered on [another] aircraft; the hptacc (high pressure turbine active clearance control) seal housing broken and the valve on MEL from station ZZZ. I am not assigned to this aircraft; nor did I open the engine cowling to inspect the hptacc ducts. I am concerned; however; this is a problem because the MEL does not address the manifold; only the valve. Flying the engine with the manifold taped/safety wired together without engineering authorization and using an MEL that does not clearly state the manifold can be damaged is a problem.
