The Diagnostic / The Situation
The next generation BMW M3 is expected to feature an inline-six engine, a configuration that has been a staple of the M3 lineup for decades. As a car enthusiast and potential owner, it’s essential to understand the technical background of this engine configuration and how it may impact maintenance and repair. The inline-six engine is known for its smooth operation, high power output, and relatively compact design. However, it also presents some unique challenges, such as a more complex cooling system and potentially higher repair costs.
Symptoms or signs to look for in an inline-six engine include unusual noises, vibrations, or temperature fluctuations. These can be indicative of issues with the engine’s timing chain, water pump, or cooling system. Regular maintenance and inspection can help identify these problems early on, reducing the risk of costly repairs down the line.

Technical Deep Dive
The inline-six engine in the next generation M3 is likely to feature a number of advanced technologies, including direct fuel injection, variable valve timing, and a twin-scroll turbocharger. These systems work together to provide exceptional power and efficiency, but they also add complexity to the engine’s design.
Common failure points in an inline-six engine include the timing chain, water pump, and cooling system. The timing chain is responsible for synchronizing the rotation of the crankshaft and camshafts, and it can wear out over time, causing the engine to misfire or run rough. The water pump is responsible for circulating coolant through the engine, and it can fail due to corrosion, wear, or overheating. The cooling system is also critical, as it helps to regulate the engine’s temperature and prevent overheating.

Step-by-Step Guide
Step 1: Prepare the Garage and Tools
Before starting work on the next generation M3, it’s essential to prepare the garage and tools. This includes clearing a workspace, gathering the necessary tools and equipment, and ensuring the vehicle is properly supported and secured.
Step 1.1: Clear the Workspace
Clear a workspace in the garage, ensuring there is enough room to work comfortably and safely.
Step 1.2: Gather Tools and Equipment
Gather the necessary tools and equipment, including a 10mm socket, 12mm socket, torque wrench, pliers and punch, multimeter, and compression test kit.
Step 1.3: Support and Secure the Vehicle
Ensure the vehicle is properly supported and secured, using jack stands and wheel chocks to prevent it from rolling or falling.
Step 2: Inspect the Engine and Cooling System
Inspect the engine and cooling system, looking for signs of wear or damage. This includes checking the timing chain, water pump, and cooling system for leaks or corrosion.
Step 2.1: Check the Timing Chain
Check the timing chain for wear or damage, looking for signs of stretching or corrosion.
Step 2.2: Inspect the Water Pump
Inspect the water pump for signs of wear or damage, including leaks or corrosion.
Step 2.3: Check the Cooling System
Check the cooling system for leaks or corrosion, ensuring the radiator, hoses, and coolant are in good condition.
Step 3: Perform Routine Maintenance
Perform routine maintenance tasks, including oil changes, tire rotations, and brake pad replacements. This will help to ensure the vehicle is running smoothly and safely.
Step 3.1: Change the Oil
Change the oil, using a high-quality synthetic oil that meets the manufacturer’s specifications.
Step 3.2: Rotate the Tires
Rotate the tires, ensuring they are properly balanced and aligned.
Step 3.3: Replace the Brake Pads
Replace the brake pads, using high-quality pads that meet the manufacturer’s specifications.
Pro Tips & Common Mistakes
When working with an inline-six engine, it’s essential to avoid common mistakes, such as over-tightening the timing chain or failing to properly secure the vehicle. It’s also important to follow proper safety protocols, including wearing protective gear and ensuring the vehicle is properly supported and secured.
Don’t do this:
- Over-tighten the timing chain, as this can cause damage to the engine.
- Fail to properly secure the vehicle, as this can cause injury or damage.
Tricks of the trade:
- Use a torque wrench to ensure the timing chain is properly tightened.
- Use a multimeter to check the engine’s electrical system.
