ABSTRACT:
An oil filter cover has a housing with a cylindrical sidewall, an open end, and an opposing closed end. A cavity in the housing extends through the open end and is adapted to receive an oil filter canister. An annular flange circumscribes the open end of the housing and extends inward from the sidewall to partially close around and seal against the oil filter canister. A piercing member extends into the cavity from the closed end to puncture the canister. The piercing member is mounted to a plate which is located in the cavity and abuts the closed end. Further, a series of longitudinal ridges extend into the cavity from the housing sidewall and are spaced circumferentially about the cavity. Each ridge extends at least partially between the open end and the closed end of the housing with some of the ridges extending to abut and hold the piercer mounting plate against the closed end. A protective sleeve is slip-fit over the housing to minimize damage to the cylindrical sidewall from a protruding structure adjacent the oil filter.
