Diaphragm Replacement Disaster: When the crankcase ventilation (PCV) diaphragm tears in N47 engines, breaking that part of the cover with a screwdriver in the industry and placing a makeshift rubber diaphragm inside, then sealing it with Japanese glue, is the biggest sabotage you can do to the engine. That cover will never hold vacuum again; the engine will draw air from outside, idle will be disrupted, and it can pump liters of oil into the intake manifold, causing the engine to run uncontrolled on its own oil and potentially explode. The only solution is to replace it with a brand new BMW F10 520d N47 Valve Cover.
Liquid Gasket Error: Applying red or black liquid silicone under this cover, which should be installed with its original gasket, can cause broken silicone pieces to clog the oil filter, leading to engine bearing failure.
The most vital upper body component of BMW's 5 Series F10 models, legendary for performance and fuel economy, is the 2.0 diesel (N47) engine; the symbol of German quality, the FEBI Bilstein brand BMW F10 520d N47 Valve Cover is now available! This system protects the camshafts and also regulates the high crankcase pressure inside the engine, which is a chronic weak point of N47 engines. Over time, due to excessive heat from the engine, an old BMW F10 520d N47 Valve Cover that has been warped or has a torn crankcase ventilation (PCV) diaphragm can lead to sudden excessive oil consumption, thick white/blue smoke from the exhaust, and completely oil-filled turbo airways. This dangerous situation, often mistakenly thought to be a "turbo failure," can be resolved by replacing it with this brand new BMW F10 520d N47 Valve Cover, made from high-temperature resistant special polymer to OEM standards, ensuring the safety of your engine block. This FEBI brand BMW F10 520d N47 Valve Cover, which comes in a plug-and-play form with its original lower rubber gasket and integrated PCV valve, cleans your F10's engine compartment of oil leaks and prevents DPF (Diesel Particulate Filter) clogging.
