If there is a large amount of oil on the sides of the engine or if you can smell burning oil, chances are it's a bad valve cover gasket.

This replacement gasket from Elring is perfect to prevent any further oil leaks.

Includes the following Seals:

  • Valve cover gasket
  • Spark plug seals

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

After the introduction of the M52TU/M54 engines, BMW observed an uptick in CCV-related issues, especially in cold regions. Vehicles operating in extremely low temperatures often encountered a blockage in the CCV dipstick hose, leading to elevated crankcase pressure and visible blue smoke from the exhaust. To address this issue, BMW introduced cold climate-specific hoses with foam insulation, preventing condensation and facilitating quicker oil warm-up. This kit incorporates top-notch reproduction cold climate hoses to ensure optimal CCV performance across all weather conditions.

The crankcase ventilation valve, known as the oil separator, PCV, CCV, or crankcase pressure regulator valve, plays a vital role in redirecting oil from your vehicle's intake system back into the engine oil pan. This system comprises numerous plastic and rubber hoses, prone to damage due to prolonged exposure to chemicals and heat.

Designed to tackle or prevent impending CCV system failures, this kit includes four foam-insulated hoses made from durable plastic capable of withstanding heat fluctuations and chemical exposure. Additionally, a new ventilation valve is included for a comprehensive and long-lasting repair solution.

Signs indicating the need for crankcase ventilation system replacement include:

Whistling sounds from the intake manifold, caused by crankcase pressure venting through holes in the CCV hoses. Blue smoke emitting from the tailpipe, indicating oil consumption. Excessive oil usage. Milky or yellowish buildup under the oil cap, suggesting condensation due to ventilation valve malfunction. If you're experiencing misfires, lean fuel codes, decreased fuel efficiency, or noticeable oil consumption, it's advisable to overhaul your crankcase ventilation system. Opt for this reliable system from Febi-Bilstein for a repair that meets factory standards and ensures consistent performance.

Oil leak on the E46 M3? The constant pressure valve, or oil pressure relief valve, is the most likely reason. This screw valve, located on the rear of the engine block behind the #2 header, has an o-ring that becomes flat over time, allowing oil to leak around it and down the back of your engine, transmission, undertray, and eventually to your driveway. If you see an oil leak around your transmission and think it's the rear main seal or from the oil pan, try replacing this first. Replacement is the only remedy as the o-ring is not available separately from BMW. This is an Original BMW part. One required.

Applications:
1993-1999 Euro E36 M3 (S50 Euro, S52 Euro engine)
2001-2002 MZ3 M Roadster, M Coupe (S54 engine)
2001-2006 E46 M3, E46 M3 CSL
2006-newer E85 Z4 M Roadster, E86 Z4 M Coupe

Upgrade your BMW engine's performance with the Athena Cut Ring Head Gasket. This gasket replaces BMW part # 11121726619 and 11121726617 and is specifically designed for M50 & M52 iron block inline 6-cylinder engines found in E34/E36 chassis. Standard OEM & MLS gaskets can only handle a certain amount of cylinder pressure before they start to leak, making the Athena Cut Ring Head Gasket the recommended choice for applications making 16+ psi. A compression leak passing the head gasket can cause a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure. Athena's gasket is crafted with premium quality reinforced M0115, an asbestos-free material that's original equipment approved and renowned for its superior quality. The AISI 304 stainless steel Cooper Rings bite into the aluminum head, providing maximum sealing capabilities around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2-bar boost. Before installation, it is crucial to have the mating surfaces of the cylinder head and block professionally cleaned and resurfaced to ensure they are completely flat. Please be aware that the gasket should have a size that is 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm. Installation instructions: Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant. Install the Cut Ring gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed. It is recommended to not use any additional sealant on the MLS gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.
