Description

Picture this: your engine, a finely tuned machine, humming along smoothly until disaster strikes. That's where the Crank Seal Guard from MaLo Industries steps in. Crafted with precision, this shield is like armor for your engine's vulnerable crank seal, tucked away behind the harmonic balancer.

Now, in the wild world of automotive upkeep, you can't afford to leave anything to chance. The N5x models, in particular, face a unique risk with their accessory belt lurking beneath common leak spots in the oil and coolant systems. Imagine this: a leak springs, and your accessory belt starts to wander from its cozy spot on the crank pulley. Next thing you know, bits of rubber from that belt are making their way into places they shouldn't be—like the timing chain, valve cover, or even clogging up the oil pickup. 

But fear not, because the Founder of MaLo Industries saw these nightmares coming and decided to do something about it. Enter the Crank Seal Guard, meticulously tested on a range of engines from N51 to S55, ensuring a snug fit every time. It's not just a protective measure—it's an investment in the long-term health of your BMW's beating heart.

So don't wait for disaster to strike—be proactive and arm your car with the Crank Seal Guard. With stainless steel bolts, washers, and a dab of Loctite included, this kit has everything you need to keep your engine safe and sound. Because when it comes to engine protection, prevention is always the best solution.

Why bother getting the Crank Seal Guard?

Due to the placement of their accessory belt beneath common leak areas in the N5x oil and coolant system. If a leak occurs, the accessory belt may begin to displace from the crank pulley. The engine's design allows small rubber fragments from the deteriorating belt to pass through the crank seal easily. These belt shards can then enter the timing chain, valve cover, or oil pickup, causing damage or engine oil starvation.

Most common reasons for the serpentine belt to come off:

  • Oil dripping from a leak of the Oil Filter housing
  • Worn out engine mounts causing power steering pulley to get in contact with subframe
  • Oil dripping from the oil cooler connection
