Valve Cover

The valve cover is responsible for sealing the internal workings of the engines' top end. Most vehicles require a replacement gasket at some point or another and newer models have plastic valve covers that get brittle and crack with age.

The factory magnesium valve covers on the S65 engine are known for developing micro-porosity, corrosion, and persistent oil leaks over time. This material is highly susceptible to oxidation, leading to unsightly surface imperfections, weakened gasket channels, and sealing issues that a simple gasket replacement won't fix.

Upgrade to this high-strength aluminum valve cover set, engineered as a direct-fit replacement for your aging OEM covers. Unlike magnesium, aircraft-grade aluminum offers superior durability, enhanced heat resistance, and complete immunity to the corrosion issues that plague factory covers. Whether you're refreshing a high-mileage M3 or seeking long-term reliability, this upgrade ensures a leak-free, worry-free solution for your S65.

Features:

Eliminates the common porosity and corrosion issues found in factory magnesium covers.

Helps maintain optimal engine temperatures and enhances long-term reliability.

Designed for an OEM-like installation without modifications.

Reduces the risk of oil leaks, ensuring a proper seal.

Resistant to oxidation and chemical exposure for a long-lasting clean look.

Absolutely — here’s a reworded version of the product description in the ECS Tuning dialect, capturing the same details with a more engaging and enthusiast-focused tone: --- **VTT Billet CNC Valve Cover – S55/N55 EWG** Say goodbye to brittle factory plastics and elevate your engine bay with the Vargas Turbo Technologies Billet CNC Valve Cover – the ultimate solution for BMW S55 and N55 EWG owners chasing reliability, performance, and high-end style. Precision-crafted from 100% CNC-machined 6061-T6 aircraft-grade aluminum, this cover ditches the OEM failure-prone plastic for a rugged, motorsport-ready upgrade that’s built to take the heat – and the boost. ### Why It Belongs in Your Build: * **Bulletproof Construction:** Solid billet aluminum means no cracks, no leaks – just unshakable strength that outlasts stock plastic by miles. * **Performance-Minded Weight:** At only 9.7 lbs, it’s a lightweight beast – just 1.8 lbs heavier than stock, but loaded with benefits. * **Anodized Armor:** Dress your engine bay with anodized color options – choose clear, black, red, blue, or gold to match your vibe. * **Custom PCV Configs:** Kills the fragile OEM PCV setup and gives you flexibility for a clean, powerful crankcase solution – whether you're keeping it stock or running a full catch can. * **Baffled to Perfection:** Integrated baffling keeps oil where it belongs, not in your intake tract. * **All-In Kit:** Comes ready to rock with ORB plugs or banjo fittings, plus -10 silicone hose – install and go. ### Heads Up on Install: Upgrading to this billet beauty wipes out the stock PCV – and that's a good thing. But to keep your engine breathing right, you’ll need an external PCV setup to maintain crankcase vacuum at idle. Want max reliability? Block off those head ports and let this cover handle the pressure without relying on a gasket alone. ### Built for Big Power: If you're running a single turbo conversion, this is your cover. It offers cleaner lines, better heat resistance, and improved fitment where it counts. ### Customize Your Cover: * **Finish Options:** Clear, black, red, blue, or gold anodizing. * **Breather Cap Choices:** Stock-style oil cap or a VTT billet one-way breather. * **Fitting Options:** Dual -10 ORB plugs, or go hybrid with a banjo and plug. * **Titanium Hardware:** Add some flair with black, burnt, or natural finish Ti bolts. * **Catch Can Ready:** Pair with VTT’s catch can for a full crankcase solution. ### Backed by VTT: Includes a 12-month warranty for confidence on and off the track. ### Price: Starting at \$1,499.00 – premium build, race-ready features, and engine bay clout to match. --- Let me know if you want this in shorter format for a product listing, social caption, or email drop.
