Please ensure your correct model is selected

BMW crankshaft seals are vital components that prevent oil and other fluids from leaking out of the engine while ensuring that the crankshaft remains properly lubricated for optimal performance. Over time, crankshaft seals can wear out, leading to common problems such as oil leaks, decreased engine performance, or even engine damage if left unresolved. Factors like age, heat, and pressure can cause seals to dry out, crack, or become misaligned, allowing oil to escape and potentially contaminating other engine components. Replacing your BMW crankshaft seal with a high-quality, OEM-approved seal ensures a proper, leak-proof fit and prevents further damage. Our selection of premium BMW crankshaft seals is designed for easy installation and long-lasting durability, providing reliable sealing to protect your engine and maintain performance. Whether you're dealing with a BMW engine rebuild or routine maintenance, our seals are the ideal solution for stopping leaks and maintaining your engine's efficiency.

The VAC Motorsports Crank Seal Guard, made of 6061 Billet Aluminum, prevents your serpentine belt from being pulled into your engine, a common problem amongst BMW N54, N55, and S55 Engines. Without a crank seal guard, the serpentine belt on N54, N55, and S55 engines is commonly sucked into the crank hub area past the crank seal, where it enters your engine and disrupts engine timing. When this occurs, the belt is shredded and clogs engine oil pickup, starving the engine and reducing oil pressure, causing catastrophic engine failure and thousands of dollars worth of damage. VAC Motorsports’ Crank Seal Guards are precision machined for perfect fitment and provide rigidity and maximum protection. We designed our guard with self-locating pilots to perfectly seal the crank hub bore and provide even, minimum clearance around the crank hub. Installation Hardware included. Made in the USA.

The BMW N52, N54, N55, & S55 engines are notorious for random serpentine belt failures. Once this belt fails on your engine, there is a strong possibility for it to wrap around your crank shaft past your OEM crank seal, and into your engine internals. Once the belt is inside your engine, it is commonly shredded, causing bits and pieces to clog up the oil pickup and potentially lead to catastrophic engine failure. The 034Motorsport Billet Crank Seal Guard is designed to be installed over the OEM BMW crank seal to prevent a failed serpentine belt from entering your engine. The 034Motorsport Crank Seal Guard is manufactured from 6061-T6 billet aluminum and anodized black to protect it from any corrosion. FEATURES: Prevent the Dreaded and Costly Premature Serpentine Belt Failure From Ending Up in Your Oil Pan, Leading to Oil Starvation and Engine Failure Machined from 6061-T6 Aluminum Anodized Black for Protection from Corrosion & Long Lasting Great Looks WHAT’S INCLUDED: 1x) 034Motorsport Billet Crank Seal Belt Guard 2x) M8x1.25x40mm - 12.9, Zinc Plated Screws
