Maintaining the peak performance and reliability of your BMW N52 engine is essential for a smooth and enjoyable driving experience. One of the most effective ways to achieve this is by replacing critical components like the valve cover, crankcase vent hose, angle connector with heating element, and cylinder sleeve. In this article, we'll delve into the numerous benefits of upgrading these vital parts, ensuring your BMW N52 operates at its best. Optimized Engine Performance: Replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve enhances your BMW N52's engine performance. The valve cover plays a crucial role in sealing the engine, preventing oil leaks and ensuring optimal valve operation. When you upgrade these components, you reduce the risk of performance-robbing oil leaks and maintain precise valve timing, resulting in improved horsepower and torque. Enhanced Reliability: Reliability is paramount for any BMW owner. These components, when aged or damaged, can lead to severe engine issues. By replacing them, you significantly reduce the likelihood of unexpected breakdowns or costly repairs, ensuring your BMW N52 engine runs smoothly and reliably for years to come. Improved Fuel Efficiency: An efficiently operating engine not only performs better but also consumes less fuel. The replacement of these components leads to better combustion, reduced emissions, and ultimately improved fuel efficiency. This means fewer trips to the gas station and a lighter environmental footprint. Reduced Maintenance Costs: Regular maintenance and repairs can add up over time. By proactively replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve, you mitigate the risk of more extensive engine damage that could lead to expensive repairs down the road. In the long term, this can translate into significant cost savings. Extended Engine Lifespan: The longevity of your BMW N52 engine is directly tied to the quality and condition of its components. When you invest in high-quality replacements, you're effectively extending the lifespan of your engine. This not only preserves the value of your BMW but also allows you to enjoy its performance for years to come. Precise Temperature Control: The angle connector with heating element is vital for maintaining optimal engine temperature, especially in cold weather. A malfunctioning or worn-out connector can disrupt temperature control, affecting engine performance. Replacing this component ensures consistent and precise temperature management. Customized Upgrades: When replacing these components, you have the opportunity to choose high-performance or specialized alternatives, allowing you to customize your BMW N52 to your preferences. Whether you prioritize power, efficiency, or specific driving conditions, there are options available to tailor your engine's performance accordingly. Included in the BMW N52 Valve Cover & PCV Valve Refresh Kit: 6 Cylinder Sleeves 1 Alternator Mounting Screw Set 1 Angle Connector with Heating Element 1 Valve Cover - Gasket Included 1 Crankcase Vent Hose

All-in-one valve cover overhaul Preventative replacement saves time and trouble later on Includes new oil separator system Replace valve cover gaskets before a leak becomes worse Replace valve cover before it cracks For the 2007 model year BMW switched to a plastic valve cover on the N51 and N52 engines. As we have seen over time the plastic can crack which leads to oil leaks, vacuum leaks, poor running, and other issues. Unfortunately, it's not just the gasket that needs periodic replacement but the entire valve cover itself. This kit includes a new valve cover, gaskets, eccentric shaft seal, and hardware. The valve cover also incorporates the oil separator which is not a replaceable item on its own. So a complete valve cover replacement will tackle multiple problem areas at once. The valve cover is the same for N51 SULEV and N52 engines. Cracked Valve Cover. The plastic used for the N52 valve cover is thin and weak in certain spots. This makes it prone to hairline or larger cracks that will leak oil and cause vacuum leaks. You might also notice rough running, especially at idle. Often a technician will go looking for a failed ignition coil, spark plug, or failed vacuum hose on the engine. And without a fault code to assist in diagnosis this can often mean wasted time and money. A cracked valve cover is a new problem area that many techs don't think to check. Oil Separator/Crankcase Vent. BMW integrated the oil separator system into the valve cover on these later engines. An internal manifold creates a cyclone effect and centrifugal force separates vapor from the liquid oil. The liquid oil is supposed to drain through the valve cover and back to the oil pan while the remaining vapor is burned up during combustion. It's a very efficient and environmentally-friendly design with very few moving parts. Unfortunately it's not perfect and eventually the internal passageways will become clogged. This problem is made worse in cars that have short drive cycles, sit for long periods of time, do not have frequent oil changes, do not see regular runs to redline, and cars in freezing climates. If the engine never reaches optimal operating temp the oil remains in liquid form or becomes sludge. This is bad news for the entire engine, leading to fouled spark plugs, rough running and misfires and even premature failure of catalytic converters and oxygen sensors. Since the oil separator system in the valve cover is not available on its own, and cleaning it is nearly impossible, the complete replacement of the valve cover is the only option. Other oil vent tubes and vacuum hoses are also recommended to get replaced at the same time. Valve Cover Gaskets. As with any rubber part, failures occur when the rubber becomes dry and brittle. The pliable rubber no longer forms a seal between the cylinder head and valve cover where it will develop an oil leak. Valve cover gaskets that leak can allow oil to seep into the spark plug holes and contaminate ignition coil boots and plugs. That can lead to rough running and misfires. A new valve cover includes new gaskets. Eccentric Shaft Seal. The seal for the eccentric shaft sensor is a known spot for oil leaks. When the seal to the valve cover fails oil can end up in the sensor itself and ruin the sensor (an unecessary $300 expense). Usually a new seal (o-ring) will stop the leaks but sometimes the valve cover is at fault too. A new eccentric shaft seal is included. All new hardware is included to avoid re-using and over-tightening the original bolts (they have a very low torque rating). Replacement requires accessing the rear of the engine with a lot of the upper plastic shrouding removed. The vent hose on the valve cover should be replaced as it is almost always broken anyway (#11157559528). The metal fuel line must also be removed and disconnected from the fuel injectors. Professional installation is encouraged if you have never done this kind of work before. Serious DIY types should have a Bentley Service Manual to use which greatly explains the process. You may also want to combine this work with the oil filter housing gasket replacement. There is no maintenance or replacement interval for the N52 valve cover. However, we have seen cracks and other failures in the 50,000-90,000 mile range. Our best advice is to plan on a major top end overhaul around the 70-80,000 mile mark. There's no mechanical downside to replacing it as prevention and it will make the engine run better and last longer.
