11 15 1 705 237 : Engine oil separator for BMW X5 E53

This engine oil separator is intended to replace a worn, clogged or faulty part on the BMW X5 E53 equipped with 4.4i M62 and 4.6is M62 engines. The oil separator, also called a crankcase breather, plays an essential role in the crankcase ventilation circuit by retaining oil particles before they reach the intake circuit. Its replacement is a natural part of a careful restoration or maintenance approach for a classic vehicle. Opting for a new part guarantees proper operation of the vacuum system and preserves the overall condition of the engine.
