VTT BMW N54 N55 Crank Seal Guard Front Main Seal/Crankshaft Seal Protector, Belt Ingestion Prevention Billet 6061‑T6 Aluminium, Black Anodised Vargas Turbocharger Technologies

BMW N54 N55 Front Crank Oil Seal Shield - CNC Aluminium Seal Plate - Black Anodised - Made by Vargas Turbocharger Technologies

Protect your straight-six from a shredded auxiliary belt being dragged past the crank pulley and into the sump. This precision CNC aluminium shield creates a solid barrier at the front crank oil seal, stopping drive belt debris from being sucked through the seal area and causing oil pickup blockage, oil starvation and costly engine damage. A small, smart reliability upgrade for N54 and N55 engines that can save a rebuild.

Why you need this on your N54 or N55

An ageing or contaminated serpentine belt can fail without warning. When it lets go, fragments can get pulled behind the damper and past the front seal into the timing case and sump. That can clog the pickup, drop oil pressure and ruin bearings. This front seal plate is designed to stop that belt pull-through before it happens on both tuned and stock cars used on the road, fast road and track days.

Key features

• CNC machined 6061-T6 aluminium for strength and accuracy
• Durable black anodised finish for long term corrosion resistance and an OE-style look
• Direct fit at the crank pulley and damper interface on BMW N54 and N55 platforms
• Prevents aux belt material from entering the engine, helping to avoid oil starvation
• Lightweight, robust and proven on daily drivers and high boost builds

We use this part on our own builds and customer cars. Feedback has been consistently positive for reliability and peace of mind, especially on vehicles running upgraded pulleys, higher power levels or frequent track use.

What you receive

• 1 x VTT billet front seal shield for N54 or N55
• 2 x extended high tensile bolts and 2 x stainless washers

Pair it with

Install alongside a crank bolt capture unit while the damper is off to add extra protection at the crank interface. This combo gives you both belt suck-in prevention and added security for the crank bolt on these engines.
