German VW Valve Covers w/ -8 AN Breather Bungs | Type 1 Pair | TIG Welded

These are original German-stamped Volkswagen valve covers, restored and modified with TIG-welded -8 AN male breather bungs and finished in semi-gloss black powder coat. Sold as a pair (left and right). They fit all VW Type 1 air-cooled engines — the standard upright flat-four used in Beetle, early Bus, Karmann Ghia, Type 3, and Thing.

Why German-stamped covers matter

The original German covers use thicker, heavier-gauge steel than modern reproductions. They resist warping under heat cycles, which is the primary cause of the persistent oil leaks owners see with cheap aftermarket covers. We start with genuine German cores, inspect each one for dents and structural integrity, and reject any that can't be brought back to spec.

Why add -8 AN breather bungs

High-displacement air-cooled builds (1776cc and up) and high-compression engines produce more crankcase blow-by than the stock breather system can vent. Routing breather lines from the valve covers to a catch can reduces pressure, prevents oil from being pushed past the seals, and keeps your engine bay clean. The -8 AN size is the standard for catch-can plumbing.

FAQ

Will these fit a stock engine, or do I need a high-performance build?
They fit any stock or modified Type 1 engine. The breather bungs are useful on stock engines too, but they're essential on 1776cc+ builds where blow-by exceeds what the stock breather can handle.

Will these fit a Type 4 engine (1972+ Bus, 411, 412, Porsche 914)?
No. Type 4 engines have a different valve cover design. These are Type 1 only.

Do I need to use both bungs?
No. You can use one as a breather and cap the other, or route both to a single catch can. Most builders use both for symmetric flow.

What's the difference between German-stamped and reproduction covers?
German covers use noticeably thicker steel and hold their shape under repeated heat cycles. Reproductions are functional but warp more easily, which is why oil leaks reappear after a few thousand miles even with a new gasket.

Do these come with hardware or gaskets?
No. Stock VW bail clips (the spring-steel hold-downs) and gaskets are sold separately. We recommend our #E22 German cork gaskets.

Are they ready to install?
Yes. Cleaned, fabricated, coated, and ready to bolt on.
