Basic Engine Health: Vital to Your Vehicle's Performance

Your engine is one of the most important components of your vehicle.

At B & M Automotive & Diesel Service in Knoxville, we offer the expertise and parts needed to maintain your engine's performance and ensure its continued reliability.

Cylinder Head Repair
The cylinder head, located at the top of the engine block, seals the cylinder and forms the combustion chamber, playing a crucial role in managing airflow and maintaining proper cylinder sealing. Inadequate compression from a faulty cylinder head can lead to driving challenges.

Engine Coolant Check
Maintaining the correct operating temperature with engine coolant fluid is critical to preventing engine distress. Your engine operates within specific temperature limits, and exceeding these can cause issues like radiator failure. Overheating may pressurize the radiator, leading to dangerous scalding water sprays. Using the proper engine coolants can help avoid these hazardous situations.

Engine Replacement
Engines convert energy into essential mechanical motion, propelling your vehicle forward. Despite their general reliability, car engines can succumb to damage and breakdowns. In such instances, don't fret; take prompt action. Deliver your vehicle to a trusted mechanic for a reliable engine replacement.

Ignition Wires & Cables
Ignition cables, or spark plug wires, are vital for transmitting the spark from the ignition coil to the spark plugs, ensuring your car's engine starts and runs smoothly. Faulty ignition cables can lead to engine misfires, poor gas mileage, illuminated engine warning lights, and vibrations.

Oil Changes
During an oil change, examining the engine oil provides crucial insights into your engine's health. Ideally, the oil should be darker than when new, maintain consistent viscosity, and contain no solid particles. Solid particles in the oil suggest deterioration of internal components like seals, which can cause rapid and extensive damage due to the engine's finely balanced mechanisms and tight clearances.

Spark Plugs
Spark plugs are essential for delivering electric current from the ignition system to the combustion chamber, and aged or neglected ones can cause ignition problems. Our automotive experts can inspect and replace your spark plugs to ensure optimal engine performance. Whether you need basic oil service or extensive engine repairs, contact us at (919) 883-4873 to get your engine running at full capacity.

Engine Repair FAQs


Is It Okay to Drive With the Engine Light On?

The short answer is "No." The longer explanation is that the light may indicate a serious engine failure, and continuing to use your car as if nothing is wrong could result in a very expensive engine repair bill. The check engine light means you should stop driving and have your vehicle looked at as soon as possible by a professional at B & M Automotive & Diesel Service in Knoxville.

What Could Cause a Check Engine Light to Come On?

Come by B & M Automotive & Diesel Service and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a routine 50K or 100K mile manufacturer maintenance service.

How Long Should an Engine Repair Take?

The time it takes to rebuild or repair an engine varies greatly, ranging from a few days for straightforward jobs to several weeks for more complex work. Regardless of the timeframe, a thorough understanding of the engine's components and strict adherence to manufacturer specifications are essential for a successful and long-lasting repair.

What Does an Intermittent Flashing Check Engine Light Mean?

Flashing check engine lights warn of severe situations requiring immediate attention. Get your vehicle to an auto repair shop as quickly as possible, or safely park it and arrange for a tow truck to take it to your preferred repair facility.

What Does Engine Repair Include?

Engine repair can include addressing issues such as head gasket leaks, worn belts, oil pan seal leaks, ignition problems, cooling system failures, and other components affecting engine performance. Repairing these problems early can help prevent extensive damage and avoid the need for a complete engine replacement. Timely repairs are key to minimizing the severity and cost of engine problems.
