The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy. When malfunctioning, your MPG and performance can suffer. Replaced fairly easily, you can restore your performance and mileage quickly. Be sure to add anti-seize on the threads to prevent it from becoming a permanent part of the exhaust. Regularly scheduled maintenance as these tend to fail slowly.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. This is a Meyle oxygen sensor for BMW's with the N52, N54, and N55 3.0L engines. This 560mm bank 1 oxygen sensor is mounted after the catalytic converter. As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

90x110x12mm - usually replaced when servicing the timing chains The front seal or crankshaft seal is one of the most difficult to replace. However, they often fail, and when they do, your car will be marking it's territory with little oil drops wherever you park. Apart from making a mess, it can also cause oil to come in contact with the pulley surfaces. Replace yours and keep your oil in your engine. The perfect time to replace this seal is when you are doing a timing replacement. You already have everything apart, so you might as well add this piece even if it hasn't failed yet as a bit of preventative maintenance.

The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create an oil sludge condition that is impossible to clear. The plastic hoses can become brittle and crack which leads to vacuum leaks and oil leaks. Thankfully, the CCV is replaceable on the early N52 engines (2006 and some 2007 models) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

This is a kit containing the oil separator, the vent hoses, and the intake manifold gaskets that are done during a typical oil separator replacement. Complete kit includes:

11617531423, Genuine BMW oil separator

11617559530, vent hose

11157522931, oil separator hose

11157567801, return hose

11157537701, extraction hose

11617547242, intake manifold gaskets (set of 6)
The intake manifold must be removed to access the oil separator so new profile gaskets are included. We also recommend (but not required) a new oil separator fitting on the intake manifold because it's one of the heated elements that vaporizes the oil as it enters the intake.

The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

This kit fits the following BMWs:
2006-2011 E90 BMW 325i 325xi 330i 330xi - Sedan
2006-2012 E91 BMW 325xi - Wagon

Keeping the oil inside your engine is extremely important to performance. Between oil change intervals, your oil can dip to dangerous levels if there is a leak you may not be aware of. The valve cover is an extremely common place for this to happen. Years of exposure to extreme temperature change degrades the gaskets and causes failure. Replace yours to keep your engine oil in your vehicle.
