Exhaust Manifold vs Extractors: Which Is Better?

Exhaust Manifold vs Extractors

The key difference between an exhaust manifold and extractors (headers) lies in performance and design. Exhaust manifolds are typically stock components made of cast iron, prioritizing durability and cost but generating more backpressure. Extractors, or headers, are aftermarket upgrades designed to improve exhaust flow, reduce backpressure, and boost engine performance, making them ideal for enthusiasts … Read more

Why Do Exhaust Manifold Bolts Break?

Why Do Exhaust Manifold Bolts Break

Exhaust manifold bolts break primarily due to extreme temperature fluctuations, which cause thermal expansion and contraction, as well as exposure to rust and corrosion from moisture and road salt. Continuous engine vibration and improper installation or over-tightening also contribute to their failure. Over time, these factors weaken the bolts, making them more susceptible to breaking. … Read more

Valve Cover Torque Spec

Valve Cover Torque Spec

Valve cover torque specs refer to the specific amount of force needed to properly secure the valve cover bolts. Applying the correct torque is crucial to prevent oil leaks, avoid damage to the gasket, and ensure a proper seal. Over-tightening can warp or crack the cover, while under-tightening can lead to leaks. The valve cover … Read more

Why Make a Valve Cover Out of Magnesium?

Why Make a Valve Cover Out of Magnesium

Magnesium valve covers are used primarily for their lightweight nature, which helps reduce overall vehicle weight, improving fuel efficiency and performance. They also offer good thermal conductivity, which aids in heat dissipation, and have vibration-damping properties that reduce engine noise. While magnesium is more expensive and requires special manufacturing processes, its benefits are valuable for … Read more

Crankshaft Lower Gasket Leak

Crankshaft Lower Gasket Leak

A crankshaft lower gasket leak occurs when the gaskets or seals around the crankshaft fail, leading to oil leaking from the bottom of the engine. This can result in oil loss, engine damage, and decreased performance if not addressed promptly. Common symptoms include visible oil leaks, low oil levels, and a burning oil smell. Repair … Read more

Relearning Crankshaft Sensor Without Scanner

Relearning Crankshaft Sensor Without Scanner

Relearning a crankshaft sensor without a scanner involves using manual methods like key cycling, throttle relearn, or a driving cycle. These techniques help the engine control module recalibrate to the new sensor position, ensuring accurate engine timing and performance. While it’s a cost-effective approach, following the specific steps carefully is crucial to avoid engine issues. … Read more

How to Tell if a Crankshaft is Forged or Cast

How to Tell if a Crankshaft is Forged or Cast

To tell if a crankshaft is forged or cast, you can check the parting line, surface texture, and weight. Forged crankshafts have a narrow, sharp parting line, smoother surface, and are generally heavier due to their denser material. In contrast, cast crankshafts have a wider, rounded parting line, a rougher texture, and are lighter. Additionally, … Read more

Radiator Stop Leak Good or Bad?

Radiator Stop Leak Good or Bad

Radiator stop leak products can be both good and bad depending on the situation. They offer a quick, cost-effective fix for small leaks, especially in emergencies or older vehicles. However, they are not a long-term solution and can cause clogs or reduced cooling efficiency, making them potentially harmful if overused or applied to larger leaks … Read more

Radiator Distilled Versus Tap Water

Radiator Distilled Versus Tap Water

When deciding between distilled and tap water for your radiator, distilled water is the better choice due to its purity, which prevents scale buildup and corrosion in the cooling system. Tap water, while convenient, contains minerals and chemicals that can lead to long-term issues like overheating and reduced coolant effectiveness. For optimal radiator health, distilled … Read more
