Detailed Description

Mahle CS54728 is an engine conversion gasket set intended for BMW 318i, 318is, 318ti, and Z3 models from 1996-1999. The set focuses on lower-engine sealing components and related service points, including the oil pan gasket, rear main seal, timing cover gaskets/seal, water outlet gasket, and water pump gasket. It does not include a cylinder head gasket or head fasteners, so it is used with the head set to create a complete sealing package. This part cross-references BMW 11 11 1 743 981 and FEL-PRO CS 26253 for the same application.

What It Helps Address

• Oil seepage from the oil pan sealing surface.
• Rear main seal leakage at the back of the engine.
• Coolant leaks at the water pump or water outlet.
• Timing cover seepage during engine resealing work.
• Incomplete sealing service when lower-engine gaskets are replaced without the matching head set.

Installation Notes and Tips

Use this set with the matching head set as noted in the fitment data. Verify all sealing surfaces are clean, flat, and free of old gasket material before assembly. Confirm the engine application before installation, since this set is specific to BMW 318i, 318is, 318ti, and Z3 fitments.
