N63 Engine Problems and How to Fix Them

Nissan released a support package for the N63 engine which addressed the majority of the issues associated with the vehicle. In particular, the package addressed issues related to the timing chain, head gasket, seals, and fuel injectors. However, some of the most common issues remain unresolved. Here we look at a few common N63 engine issues and how to fix them. Hopefully, this article will help you resolve these problems and make your car better than it was before.

High oil consumption

The N63’s high oil consumption is one of the main engine problems that can cause a BMW owner to be concerned. It is linked to the fact that the piston rings are becoming gummed and degrading. High oil consumption can appear in the N63’s engine after a few thousand miles or even 50,000 miles. If it does not resolve itself, it may require an overhaul with new piston rings. Another possible problem is a hydrolock which occurs after a prolonged period of downtime in the engine. If the problem is caused by a failing piezo injector, it can be solved by changing the injectors in the engine.

The N63 engine series was first manufactured in 2008 and is currently installed in almost all new BMW large models. There are also sports versions of the N63 with up to 600 hp. But the N63 has had many problems since its launch. Despite the performance of these cars, the N63 engine continues to be plagued with high oil consumption. While BMW has released several service packs that address this problem, it’s unclear how many problems it has fixed yet.

BMW has responded to the oil consumption issue by introducing a larger battery and changing the recommended interval for oil services from 15,000 miles to 10,000 miles. They have also incorporated a new battery with the oil service as a preventative measure. High oil consumption in an N63 isn’t considered normal. Many factors contribute to this increased oil consumption. There are two reasons for this problem. One is that the turbocharged engine requires more oil than a conventional engine. The other is that turbocharged engines are designed to use more oil.


There are several reasons why the BMW N63 engine experiences frequent hydrolock. The high pressure fuel injector units are a common culprit. These were replaced as part of the Customer Care Package, but the updated versions do not mix with the outgoing ones. If one injector breaks, the engine may become unresponsive and begin to hydrolock. If this occurs, the vehicle may eventually fail due to a chain reaction. It is extremely difficult to diagnose and repair this problem.

The best way to prevent a hydrolock is to identify the source of the fluid intrusion. The most obvious cause is a flooded vehicle. It is self-explanatory. If the engine is not running, it can cause a flooded vehicle to hydrolock. This can be fixed by pulling the spark plugs. However, in more severe cases, removing the spark plugs may be necessary. Even though it is simple to remedy a hydrolock, determining the source of the fluid intrusion is critical to preventing further episodes.

There are other problems with the timing chain. This engine’s first version had timing chain issues causing additional wear and tear on the valve-train. These issues could lead to decreased performance and a high repair bill. BMW acknowledged the issue and replaced affected vehicles with new timing chain guides and tensioners. But this problem still persists, so it is important to schedule an appointment with a mechanic right away. If you can’t wait until the engine stops, consider renting a professional service to check the timing chain guide and tensioner.

Fortunately, BMW has a solution to the problem: the N63 has a Customer Care Package that addresses the most common N63 issues. It includes service for the crankcase vent lines, low-pressure fuel sensors, and more. While this may not be the most effective way to fix a problem, it will certainly ensure that your car continues to function properly. In the meantime, if the hydrolock N63 battery charger stops working, you may need to purchase a new battery.

Ignition misfires

BMW N63 engine problems include several issues related to the ignition system. The first issue was a battery draining issue. BMW quickly responded to the issue with their Customer Care Package. BMW also made changes to the running system during production. The engine’s performance was impacted, but the car’s owner did not have to worry about the battery draining issue. The following are some tips to fix the problem.

Check for leaky injectors. You should replace your old injector if your car is experiencing ignition misfires. Old ignition wires are also a possible cause of the problem. The rotor and cap may need replacing as well. Replace these components immediately, if possible. A new ignition coil pack is a relatively inexpensive solution. But if you’re still experiencing misfires, you can contact your car’s dealership to receive a free diagnosis and repair.

If you’ve noticed an increase in fuel mileage after replacing your old spark plugs, it’s most likely related to the exhaust gas. This engine uses more gas and increases emissions. BMW may have been guilty of false advertising if it didn’t stop replacing batteries after every oil change. In an effort to address this problem, BMW replaced the batteries at every oil change, instead of the recommended 15,000-mile interval. If you’ve had your car serviced at the dealership, they may have changed this to every 1,000 miles.

The cylinders on the BMW N55 engine are prone to sticking open. The N20 was the replacement for the naturally aspirated 335i engine. The BMW Car Club of America is one of the largest automotive clubs in the world, and this association promotes the use of natural aspirated engines. It is also important to check for the ignition coil. The misfired fuel injectors can cause check engine lights to come on, as well as bad fuel consumption.

Misaligned connecting rod bearings

If you own a BMW N63 or N52, you’re probably familiar with these common problems. But before you get started, let’s discuss what misaligned connecting rod bearings really are and how you can fix this common problem. Here are five ways to fix misaligned connecting rod bearings:

The first step is to change the oil. BMW has a special Customer Care package that addresses the most common problems with the N63 engine. However, this does require extensive labor and repair costs. And you’ll be out of luck if you try to fix it yourself. Then you’ll have to spend a ton of money. That’s why misaligned connecting rod bearings are so expensive.

Another problem that affects BMW N63s is their oil consumption. Many owners report that the new N63 does not lean on oil in the first hundred kilometers, but after that point the oil consumption is a quart per thousand miles. It’s caused by problems with valve stem seals, clogged oil draining nozzles, and shrunken compression rings. All of these factors increase oil consumption, which deteriorates the seals in the engine.

The next step is replacing the connecting rod bearings. You must be mechanically inclined and have the right tools. To replace these bearings, first remove the front subframe. Remove the steering column, and disconnect the control arms and steering rack. Next, remove the oil pan, which will allow you to access the connecting rods. Ensure you don’t damage the engine by over-torqueing the bearings.

Batteries that do not last long

One of the most frustrating things about the BMW N63 engine is that its batteries don’t last as long as they should. That’s because the twin-turbo V8 chews up batteries. The car’s manufacturer should have fixed the problem long ago, but they didn’t. So why is it happening now? And how can I solve the problem? Read on to learn more.

One of the biggest problems is that the BMW CCP covers up the problem by recommending that owners change their batteries every time they get their cars’ oil changed. The problem is that BMW can’t fix the underlying problem, so they’re merely recommending you change your battery every time you get your oil changed. So the only solution to the problem is to replace the engine’s battery. This way, you’ll get your money’s worth out of your car.

The BMW N63 engine is notorious for its excessive oil consumption and battery life. In addition, the battery’s power drain is so rapid that replacement is required every year or 10,000 miles. BMW issued a technical service bulletin SIB-11-01-13 to dealers to address the problems with this engine. The bulletin recommends adding about 20 quarts of oil between oil changes. The problem has been so widespread that BMW has created a customer care package to compensate its customers.

The problem has been a long time coming for BMW fans. Battery chargers are a crucial component of BMW’s N63 engine. BMW’s Efficient Dynamics pushes fuel saving components and other ways to boost fuel economy, but one of the most crucial components of the engine is the battery charger. The BMW N63 battery charger relies on coasting to recharge the batteries. But the problem is that the BMW N63 engine requires more energy to recharge batteries than its European counterpart.
