BMW N63 4.4L Vent Pipe

The BMW N63 4.4L Vent Pipe addresses common issues with oil separators freezing in cold weather conditions. This problem often occurs if the vehicle is driven before it is fully warmed up, leading to a howling noise and multiple oil leaks. The crankcase breather valve in the vent pipe purges oil vapor from the engine block into the valve cover. However, condensation can sometimes cause the valve to freeze, which may result in the oil separator system failing, cracking, or disintegrating. This replacement vent pipe ensures proper function and prevents costly damage by maintaining the integrity of the oil separator system.

Benefits:

  • Prevents Freezing Issues: Reduces the risk of oil separator failure in cold weather conditions.
  • Eliminates Oil Leaks: Helps prevent leaks caused by frozen oil separators.
  • Ensures Proper Ventilation: Maintains effective purging of oil vapor from the engine block.
  • Durable Construction: Built to withstand harsh weather conditions and engine stress.
  • Direct Replacement: Designed to fit seamlessly with BMW N63 4.4L engines.

For Alternator / Water Pump Belt

Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

OEM Schaeffler (INA, LuK, & FAG) is an engineering company that focuses on high-performance, precision manufacturing. With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.

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!


NOTE: These BMW's may have been equipped with either a mechanical or hydraulic tensioner. Only for cars with Hydraulic Belt Tensioners. Please check before ordering.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies.

The roller rocker arms transfer the rotational force of the camshaft to open the intake and exhaust valves. One end is raised and lowered by the rotating lobe of the camshaft, while the other end acts on the associated valve stem. If a roller rocker arm has failed you may experience a constant ticking noise during engine operation, or alternatively if the rocker arm has broken, you will receive multiple misfires and a rough running engine.

This is an OEM INA Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc). OEM replacement for BMW part # 11281720039 and 11281715630.

These King SI-Series bearings are recommended for OE applications. These bearings are designed for aftermarket gasoline or diesel engine rebuilding and performance engines with OE crankshafts. These King SI-Series bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. These King SI-Series bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow.

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).
