Description
Protect your BMW engine from potential serpentine belt failures with the VTT Billet Crank Seal Guard. Known for its reliability, this essential upgrade prevents catastrophic engine damage by blocking the serpentine belt from being sucked into the crank seal and oil pan—a common issue in the BMW N54, N55, and S55 platforms.
Serpentine belt failure can lead to severe engine damage when the belt is drawn behind the front damper and pushed past the crank seal into the oil pan. This can result in oil pick-up blockage, causing engine failure and requiring costly repairs involving sub-frame removal and oil pan access.
The VTT Crank Seal Guard offers a straightforward, cost-effective solution to prevent such incidents. It installs over the front crank seal to protect the belt, ensuring your engine remains safe from oil starvation and other belt-related damage.
Key Features:
- Durable Construction: Made from 100% billet 6061-T6 aluminum, anodized black for corrosion resistance.
- Reliable Design: Unlike other options, it features no welds on tabs or bent thin steel pieces, ensuring long-lasting durability.
- Affordable Protection: Cost-effective solution compared to engine repair or replacement.
- Complete Kit: Includes the crank seal guard, two extended 12.9 grade bolts, and two stainless washers.
Installation Recommendation:
- We highly recommend installing the crank seal guard alongside a crank bolt capture (CBC) since the damper needs removal. This combination helps eliminate the risk of a spun crank hub and enhances overall engine protection.
- Purchase the crank seal guard and CBC together to receive a bundled discount.
