MST Billet Valve Covers, Bluelue

OVERVIEW

Elevate your air-cooled engine''s reliability and aesthetic appeal with the MST Billet Valve Covers in a striking blue anodized finish. Engineered for the serious VW enthusiast, these valve covers are a massive upgrade over the flimsy factory stamped-steel versions and standard bale-wire clips that are notorious for leaking and warping under heat. CNC-machined right here in the USA from high-grade billet aluminum, these covers provide a rigid, flat sealing surface that ensures your oil stays inside the engine where it belongs. The standout feature is the ingenious "no-slip" gasket lip, which prevents the valve cover gasket from sliding out of place during installation or under high crankcase pressurea common headache for engine builders. Whether you are running a stock 1600cc or a high-performance stroker engine, these covers offer the structural integrity needed to maintain a perfect seal for years to come.

Beyond their leak-proof construction, MST has designed these covers with high-performance breathing in mind. Each cover comes pre-drilled and threaded to accept a 3/8'' NPT fitting, making it easier than ever to integrate a custom breather system or oil catch can setup. The internal walls are specifically reinforced at the port locations to provide maximum thread engagement, ensuring your fittings stay secure even in high-vibration environments. To further guarantee a dry engine bay, the mounting bolts include dedicated o-rings that seal the bolt holes perfectly. Finished in a brilliant blue anodizing, these covers don''t just perform betterthey transform your engine bay into a show-quality masterpiece. Designed specifically for stock-style cylinder heads, they offer a bolt-on solution that combines American-made precision with the rugged durability required for daily drivers, off-road sand rails, and drag strips alike.

PRO TIPS

1. Perfecting the Gasket Seal

Even with the superior no-slip lip design of the MST covers, gasket preparation is key to a lifetime of leak-free operation. I always recommend using a high-quality cork or rubber-steel core gasket. Apply a very thin, even layer of Gasgacinch or a similar weatherstrip adhesive only to the side of the gasket that mates with the billet cover. Let it get tacky before pressing it into the cover. This "bonds" the gasket to the cover so that when you perform valve adjustments in the future, the gasket stays perfectly seated on the cover rather than sticking to the cylinder head and tearing. Never use RTV silicone on these gaskets, as it can act as a lubricant and cause the gasket to "squish" out of place when tightened.

2. Torque and O-ring Maintenance

One of the most common mistakes when switching from bale-style to bolt-on covers is over-tightening the mounting bolts. Because these are billet, they won''t flex like tin covers, so you don''t need to crank them down to get a seal. Snug them down evenly until the o-ring on the bolt is compressed. Over-torquing can lead to stripping the threads in your rocker shafts or damaging the o-rings. Speaking of o-rings, always inspect the small rubber seals under the bolt heads during every oil change. If they look flattened or cracked, replace them immediately to prevent "weeping" from the bolt holes. A tiny dab of clean engine oil on the o-ring before installation helps it seat without binding.

3. Optimizing Your Breather System

The 3/8'' NPT ports on these covers are a game changer for high-performance engines. If you are running a displacement larger than 1776cc or high-lift rockers, your engine generates significant internal crankcase pressure. I highly recommend utilizing these ports by installing 3/8'' NPT to AN-8 or AN-10 fittings and routing them to a vented breather box. This reduces pressure on your main seals and prevents oil from being pushed past the rings. If you are running a stock engine and don''t require external venting, be sure to use high-quality NPT pipe plugs with a touch of Teflon tape or thread sealant to ensure a vacuum-tight seal on the unused ports.
