BMW 3/5/7/8/X/Z Series E Chassis Engine Gasket Repair Kit – Valve Cover & Cylinder Head Gaskets – Replaces Part Nos. 11129070990, 11121437395, 11421719855

Refresh multiple common sealing points on your BMW engine with this replacement gasket repair kit, designed for compatible E36, E46, E39, and other E chassis applications. This kit combines several important engine gaskets that are commonly serviced as vehicles age, helping address oil seepage, vacuum-related sealing issues, and deterioration caused by years of heat cycles. BMW engines from this generation are known for strong mechanical durability, but the surrounding rubber and sealing components naturally harden and lose elasticity over time. Once the original gaskets begin to shrink, crack, or flatten, oil can start leaking around the valve cover, cylinder head sealing surfaces, or oil housing area. Replacing worn gaskets helps restore a cleaner, more reliable seal while reducing the risk of oil reaching surrounding engine components. The valve cover gasket seals the upper portion of the engine and helps prevent oil from escaping around the cylinder head. A failed valve cover gasket can lead to visible oil seepage, burning oil smells, smoke from oil contacting hot exhaust components, and contamination around ignition components. The included cylinder head-related gasket provides an additional sealing component for compatible engine applications and is designed to replace the corresponding factory gasket where applicable. Manufactured from durable automotive-grade sealing materials, each gasket is designed to withstand engine heat, oil exposure, pressure changes, and repeated thermal cycling. Key Features Multi-Gasket Engine Repair Kit: Includes replacement gaskets for several commonly serviced engine sealing points. Valve Cover Gasket Replacement: Helps prevent oil leaks from the upper engine and restore proper sealing around the cylinder head. Cylinder Head Sealing Component: Includes the corresponding replacement gasket for compatible engine applications. Helps Reduce Oil Leaks: Replacing hardened or flattened seals can help restore proper oil containment and reduce engine-bay contamination. Heat-Resistant Construction: Manufactured from materials designed to tolerate engine temperatures, oil exposure, and repeated heat cycles. Factory-Style Replacement: Designed to replace the corresponding original BMW gasket components without altering the factory sealing layout. Ideal Preventative Maintenance: A practical service item for aging BMW engines with original or deteriorated seals. Restore proper sealing and reduce common oil leaks with a gasket kit designed for older BMW E-Chassis applications. Replacing worn seals can help keep the engine bay cleaner, reduce oil loss, and prevent leaking oil from damaging surrounding components. FITMENT: BMW E-Chassis Models BMW 3 Series E36 - 11/1989-08/2000 E46 - 04/1997-08/2006 BMW 5 Series E34 - 01/1989-06/1996 E39 - 02/1995-12/2003 E60 - 12/2001-04/2013 E61 Touring/Wagon - 10/2002-02/2005 BMW 7 Series E32 - 03/1991-04/1994 E38 - 07/1993-07/2001 E65 - 07/2002-02/2005 E66 Long-Wheelbase - 09/2002-02/2005 BMW 8 Series E31 Coupe - 12/1992-05/1999 BMW X3 E83 - 01/2003-07/2006 BMW X5 E53 - 08/1999-09/2006 BMW Z3 E36 Roadster / Coupe - 04/1996-06/2002 BMW Z4 E85 Roadster - 01/2002-08/2008 E86 Coupe - 10/2005-08/2008 BMW Z8 E52 Roadster - 12/1998-07/2003 Compatibility Notes Fitment has been consolidated from the overlapping application lists provided. Verify chassis, production date, and existing part configuration before ordering. The E60 end date listed as 04/2023 appears abnormal for this chassis and should be verified before publishing. The included gaskets only fit applications using the corresponding factory part numbers and sealing configurations. Compare the original gaskets and mounting surfaces with the replacement parts before installation. Oil leaks can originate from multiple areas, including the valve cover, VANOS lines, timing covers, oil pan, crankshaft seals, and oil filter housing. Professional diagnosis is recommended if the exact source of the leak has not been confirmed. Replaces Part No. 11129070990 Replaces Part No. 11121437395 Replaces Part No. 11120030496 Installation Professional installation is recommended. Allow the engine to cool completely before beginning service. Remove the necessary engine covers, intake components, ignition components, and surrounding hardware required to access the gasket being replaced. Clean all mating surfaces thoroughly before installing the new gasket. Do not use sharp tools that may gouge aluminum sealing surfaces. Inspect the valve cover, oil filter housing, and surrounding components for cracks, warping, or other damage before reassembly. Install all gaskets in their correct orientation and torque fasteners to the proper BMW specifications. Replace any one-time-use seals, washers, or hardware required by the specific engine application. After installation, inspect the engine for leaks once it reaches operating temperature.
