It is a well-known issue on the BMW N54/55 platforms that your serpentine belt can fail for various reasons. When this happens, there is a high chance of the belt getting sucked behind the front damper pulley and then being pushed past the crank seal into your oil pan. From there it can get sucked into the oil pick up causing total engine failure. Even if you do not lose the engine, it is a COSTLY repair to remove the sub-frame and drop the oil pan to remove the belt. The best way to combat this is to watch for oil leaks and keep up on your maintenance. BUT, even with those preventative measures, pre-mature belt failure can occur. This crank seal guard installs over your front crank seal and will keep the belt from being sucked in if a belt failure does occur. This is a cheap way to ensure you do not end up having to replace your motor from oil starvation due to an ingested belt. Vargas' seal is different from those already on market in two major ways. Firstly, it is not offensively priced. Secondly, it is 100% billet with no welds on the tabs to break, no cheap bent thin steel pieces. 100% Billet 6061-T6 aluminum, anodized black for long-term corrosion resistance. Crank Seal Guard includes: One VTT Billet N54/55 Crank Seal Guard Two extended 12.9 Grade bolts, and two stainless washers We highly recommend you install WITH a crank bolt capture at the same time, as you have to remove the damper anyway. Then you will get the benefit of helping eliminate the dreaded spun crank hub and the crank seal issue

BMW has a seemingly endless number of fans of the N54/N55/S55 engines, three straight-six turbo engines that are each capable of 750+ horsepower, but that doesn't mean they were without their faults! BMW's N54 had a notoriously rocky start with reliability due to multiple issues such as fuel injectors failing, turbos failing, serpentine belt failure, crank hubs coming loose, and more... BMW made multiple attempts to fix the issues plaguing the N54, but they could only do so much and the fixes rolled out seemed temporary at best. Following the N54, BMW released their updated N55 and S55 engines, giving many people hope that these engines would address the previous issues. Unfortunately, this was only some-what the case. Crank hubs and crank bolts continued to loosen over time and serpentine belts continued to shred themselves and get pulled into the oil pan through the front main seal. For all three engines, this meant a single failure could effectively turn your engine into an oversized paperweight. Luckily for us, the BMW community is full of skilled enthusiasts who have gladly taken up the task to offer solutions! The first headache to be addressed was the Crank Hub and Bolt. Using a simple plate that fits perfectly over your crank hub's hex-head bolt and mounts up against the damper, the crank bolt is effectively locked in place, preventing it from being able to back out until the plate is fully removed. Next up was the serpentine belt failures. It's not known what exactly causes the serpentine belt to split, but once it does, the pieces hanging off of the belt wrap around and behind the damper. This leads to the belt breaking up into smaller pieces and eventually getting pushed between the crank hub and rear main seal into the oil pan. These small pieces of debris get caught in and block the oil pickup, preventing oil flow and leading to engine failure. To prevent this, multiple aftermarket companies came up with their own versions of Crank Seal Plates. This plate is installed behind the front damper, blocking the opening that allows the serpentine belt to pass between the crank hub and seal, keeping debris out of your oil pan! Also included in this kit are the components to service your front Oil Cooler/Filter Housing gaskets, refresh your drive belt system, and install the aftermarket upgrades. Kit Features and Contents: Vargas Turbo Crank Bolt Capture Vargas Turbo Crank Seal Plate OEM Accessory Belt OEM Belt Tensioner & Idler Pullies Liqui-Moly Longtime High Tech Engine Oil (5w-30) - 7 Liters OEM Hengst Oil Filter OEM Oil Filter/Cooler Housing Gaskets TMS Oil Change Sticker Genuine BMW Full-Strength Coolant - 1 Liter Looking to go even further and upgrade your Crank Hub as well?

Every time the cylinders fire, torque is transferred into the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torque imparted by the cylinders are in synch with the vibrations in the crankshaft, which results in a phenomenon called resonance This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure. The accessory pulley acts as a balancer and prevents these vibrations from destroying your crankshaft.

If you are breaking crankshafts and oil pumps, the cause may be a mystery to you as it has been to many of our customers. We know that controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive. ATI Performance Products has partnered with VAC Motorsports to develop new dampers for BMW 2.5L, 2.8L, 3.0L and 3.2L straight-6 engines found in the E36 and E46 M3, E9X and E6X, as well as newer Z3s and Z4s. These dampers eliminate crankshaft harmonic vibration, which allows the engine to produce more horsepower and torque, while also reducing internal engine wear at the same time. Broken oil pumps and timing chains will be a thing of the past! When used with a VAC accessory pulley, these dampers are a direct replacement over the OEM balancer. They have a 7” outer diameter and include OEM style timing alignment tabs. BMW enthusiasts should know that all ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition. The advantages of the ATI SuperDamper include eliminating vibration issues with inline 6 engines equipped with lightweight clutch and flywheel assemblies, reduced bearing, engine accessories, oil pump wear, and compatibility with underdrive pulleys. Includes lightweight VAC Billet Crankshaft Pulley.
