## What Cars Have N63 Engine?
The N63 engine is a 4.4-liter twin-turbocharged V8 engine produced by BMW since 2008. It is a direct-injection engine with Valvetronic variable valve timing and Double-VANOS variable camshaft timing. The N63 engine is available in two versions: the N63B44O0 and the N63B44A. The N63B44O0 produces 402 horsepower and 443 lb-ft of torque, while the N63B44A produces 445 horsepower and 487 lb-ft of torque.
The N63 engine is used in a variety of BMW models, including:
– BMW 5 Series (F10, F11, F07)
– BMW 6 Series (F12, F13, F06)
– BMW 7 Series (F01, F02, F03, F04)
– BMW X5 (F15, F85)
– BMW X6 (F16, F86)
## BMW N63 Engine Problems
The N63 engine has been plagued by a number of problems, including:
– **Timing chain failure:** The timing chain is a critical component of the N63 engine, and its failure can cause catastrophic engine damage. The timing chain is made of a lightweight aluminum alloy, which is prone to stretching and breaking.
– **Valve stem seal failure:** The valve stem seals are designed to prevent oil from leaking into the combustion chamber. However, the valve stem seals on the N63 engine can fail, allowing oil to leak into the combustion chamber and cause smoking and engine damage.
– **Turbocharger failure:** The N63 engine uses two turbochargers to boost engine performance. However, the turbochargers on the N63 engine can fail, causing a loss of power and engine damage.
– **High-pressure fuel pump failure:** The high-pressure fuel pump is responsible for delivering fuel to the injectors. However, the high-pressure fuel pump on the N63 engine can fail, causing a loss of power and engine damage.
## BMW N63 Engine Recall
In 2019, BMW issued a recall for all N63 engines produced between 2010 and 2016. The recall was issued due to a potential timing chain failure. BMW has since updated the timing chain on the N63 engine, but it is important to note that the timing chain on older N63 engines may still be at risk of failure.
## Conclusion
The N63 engine is a powerful and efficient engine, but it has been plagued by a number of problems. If you are considering purchasing a BMW with an N63 engine, it is important to be aware of the potential problems and to factor in the cost of potential repairs.
