USS Zumwalt Sidelined in Panama Following New Engineering Casualty

I'm fresh out of lube oil coolers. Anyone have any spares, or are yours made in China, too?
"The latest [propulsion] casualty follows an incident in September following the ship’s transit from shipbuilder General Dynamics Bath Iron Works, Maine to Naval Station Norfolk, Va. in which the crew discovered “a seawater leak in the propulsion motor drive lube oil auxiliary system for one of the ship’s shafts,” the Navy told USNI News at the time. A service official told USNI News the most recent incident is similar. The service has narrowed down the likely problem to lube oil coolers leaking. The service replaced all four lube oil coolers following the September casualty.
