Every rib, radius, and internal passage was designed, prototyped, and refined in-house before it ever reached production.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eBillet Construction\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCNC-machined from a solid billet blank, replacing the factory’s pressed sheet metal cover with something in a different league entirely for strength and rigidity. No oil canning, no flexing under heat and vibration, no denting from a stray tool — just a cover that seals true and stays that way.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIntegrated Baffle System — Replaces Factory PCV\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe factory TD42 PCV vents crankcase gases to atmosphere, and it does its job — but it’s restrictive by design. At high revs, that restriction lets crankcase pressure build, pushing more oil vapour out with it than you’d like. This cover replaces the factory PCV with a fully integrated internal baffle system that flows significantly more gas, keeping crankcase pressure lower and more consistent right through the rev range.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe baffles themselves are sealed in place by a dedicated baffle plate and face towards the front of the motor, so gravity does the work of guiding separated oil straight back down into the engine rather than letting it pool or get carried back out with the next surge of crankcase gas.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFor engines that breathe particularly heavy, there’s also room built into the design above the oil pickup for steel wool or E85 foam to be added.

A good example: cut-outs positioned specifically to clear the glow plugs, so you’re not fighting the cover every time you need to pull one for service. It’s a small thing on paper, but it’s the kind of detail that only shows up when a product has actually been designed around the engine it sits on, not just modelled off it.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAN Fittings for a Neater Setup\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe -12 ORB outlet is designed around AN fittings, so routing your crankcase gases wherever you need them to go is clean and straightforward — no more improvising with hose clamps and rubber tubing.
