If you’re looking for a used N55 engine for sale, there are a number of options available. First, you need to know which engine type you have. Next, you’ll want to learn about the compression ratio of the N55 engine. Finally, you should know how to replace the oil in your N55 engine. This will ensure that you get the most out of your vehicle’s engine.
N55 engine oil change kit
When it comes to the maintenance of your BMW, a proper oil change is critical. This prevents sludge buildup and ensures the lubrication of the engine at all times. Changing the oil is recommended every 5k miles or so to prevent wear and tear on your engine. Using the correct motor oil can also improve your vehicle’s performance and service life.
A common problem with the N54 and N55 engine is a leaky valve cover. These leaks are caused by a faulty valve cover gasket. This gasket degrades over time, and if not repaired in a timely manner, oil will leak out onto the drive belt and tensioner belt. This causes the belt to slip and can cause engine internal damage.
The Genuine BMW N55 Engine Oil Change Kit contains a set of oil filters and gaskets. This kit is suitable for use with the N55 engine on MY2016 and later vehicles. It also fits F22/23 M235 and F3x 335. This oil change kit contains everything needed to change the oil in turbo models.
The N55 engine is relatively reliable, but it can still be tuned for maximum performance. This engine produces impressive horsepower and torque.
N55 engine oil leaks
When a N55 engine develops an oil leak, it can be a very serious problem. The oil dripping onto the belts can damage them, and the leak may also damage the internal components of the engine. In the case of severe oil leakage, it may lead to an engine overheating or breakdown.
Typically, this problem is due to a malfunction of the high-pressure fuel pump (HPFP). HPFPs spout fuel into the cylinders through a direct injection system. Usually, this is an issue with 2010-mid 2011 N55 models. Fortunately, BMW solved this issue in late 2011 by installing an effective HPFP.
Another common cause of N55 engine oil leaks is a faulty valve cover gasket. This gasket mates to the motor and the heat exchange unit. But this gasket can fail over time due to wear and age. As a result, the gasket becomes cracked and oil leaks and oil buildup will occur.
Fortunately, the N55 engine is relatively reliable, albeit with a few hiccups. In most cases, the engine is relatively simple to repair. The most common parts to replace are the valve cover and gasket, the oil filter housing gasket, and the VANOS solenoids. Though most of these parts are not expensive, they add up. And the cost of service is higher if you take the car to a BMW dealership or independent repair shop.
N55 engine vs N54 engine
The N55 engine uses one large turbocharger in place of two smaller ones. The turbocharger has a twin-scroll compressor housing, and is fed by three exhaust primaries on the exhaust side. The single turbo helps the engine operate more efficiently and with less lag. It also helps reduce emissions and improve fuel economy. The engine also features Valvetronic variable valve lift.
While the N54 was launched in 2006, the N55 used a single turbo instead of two, making it more powerful. The power of the N54 was 306bhp, but this increased to 326bhp in the F01 740i and 340bhp in the F01 Z4 from 2010 onwards. The N54 was replaced by the N55 in 2009, and uses a single turbocharger.
Despite the differences in performance, both engines are generally reliable. The N54 has more power, but is unreliable and expensive to repair. The N55 has improved reliability, which helps it compete with its rival. This makes it a better choice for performance-minded drivers. If you’re looking for a more reliable and fun engine, the N55 is the way to go.
If you’re thinking of buying an N54, it is better to invest in a PS185 or PS220 piggyback ECU. These boost controllers will increase the car’s boost by up to 400hp. Moreover, a PS185-PS520 piggyback ECU will help you tune the engine and increase its performance. But you should also note that the N54’s diverter valves are not designed to handle this amount of boost. But there are some bolt-on modifications that will allow you to get up to 450hp.
N55 engine internals
If you are in the market for replacement BMW N55 engine internals, there are several reasons to consider them. This engine was introduced with some of the same problems as the N54, but it was a big improvement. The waste-gate rattle, water pump, valve cover, and oil filter housing are still common problems, but the overall reliability of the N55 is far better than that of the N54.
BMW has made the N55 engine in-house. It has a DOHC valve train and a redline of 7000 RPM. There are many enthusiasts who claim that this engine can last for more than 150,000 miles. Some have even claimed to have run it for as many as 200,000 miles.
The N55 engine has been modified to produce over 400hp, and an aftermarket turbocharger can increase this power. The N55 is a weaker engine than the N54, but it can still be tuned to produce more power. If you are considering upgrading the N55 engine to a higher-power model, you should consider buying an aftermarket turbocharger and an uprated charge pipe.
The valve cover is also prone to cracking and leaking, and you may want to consider replacing it. While this isn’t the most common problem, it can lead to significant engine damage. The gasket sits underneath the plastic valve cover, which is often difficult to remove and replace.
N55 engine warranty
The BMW N54 and N55 engines share common engine issues, including leaking valve covers and PCV valves. Despite being made of durable plastic, these components are susceptible to damage from high temperatures, which can cause cracks and leaks. While this issue may not cause an immediate problem, it can result in excessive oil buildup and can result in engine failure.
Although the N55 engine is fairly reliable, it can still experience problems. The four most common parts that can fail are the valve cover and gasket, the oil filter housing gasket, and the VANOS solenoids. Fortunately, most of these components aren’t expensive to replace. However, the bill can be substantial, particularly if you take the vehicle to a BMW dealership or independent repair shop.
