A method for temporarily sealing a turbocharger compressor outlet and the seal for doing same are disclosed. The seal may include a layer of lubricant, a cover, and a layer of heat-shrink material. The seal creates a temporary water-tight seal around a turbocharger compressor outlet preventing damage to the inside of the turbocharger while the turbocharger is not in use.

A machine includes a threaded fastener connected to, and positioned adjacent, a maintenance feature. A removable cover blocks access to the maintenance feature and includes a captive fastener assembly. The captive fastener assembly includes a barrel with an internal passage separating a tool opening from a fastener opening, and the internal passage is divided into a cage volume and a fastener passage by an internal thrust surface. A retention component that defines a tool passage through a capture surface is mechanically mounted in the barrel adjacent a tool opening. A captured fastener is trapped to move between the capture surface and the internal thrust surface in the cage volume. The captured fastener includes an internal tool engagement surface oriented toward the tool opening and threads oriented toward the fastener opening.
