The BMW N63 rear cover is a metal plate that covers the rear of the BMW N63 V8 engine. It helps to seal the engine and prevent oil leaks. Over time, the original sealing gasket becomes brittle and does not seal, causing leaks between the engine and transmission bell housing. This repair can be very expensive and is usually misdiagnosed for a rear main seal. The AGA Updated N63 Rear Cover is an inexpensive alternative, made of 6061 billet aluminum. This kit includes the rear cover, viton o-ring, alcohol wipe, scotch-brite pad and o-ring grease. BMW Part # 11142446298 & 11148483799 BMW Service Bulletin (SIB) 11 09 16
