It fails when oil pressure drops, clearances go out of spec or debris passes through the bearings. Typical symptoms are a deep knock under load, low oil pressure at idle, metallic debris in the oil and visibly scored or blued journals once the sump is off.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine code\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eB38A15A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eListed applications\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOE \/ cross-reference numbers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e764093005, 11217640930\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSupplier part number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eB38A15A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCrankshaft length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e48*21*25.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWarranty (as stated)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12 Months Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMinimum order\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 piece\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eFitment checks before ordering\u003c\/h3\u003e\u003cp\u003eFitment must be confirmed against the engine code (B38A15A) and the OE number on the part being replaced.

New bearing shells matched to the measured journal size are required, and the oil ways should be cleaned and the rear seal replaced while access is open.
