VW MK3 Golf, Jetta, Passat & Vento 1.9L AAZ Turbo Diesel Valve Cover

OEM valve cover for the Volkswagen 1.9L AAZ Turbo Diesel engine — the pre-TDI indirect injection diesel that powered MK3 Golf, Jetta, Passat, and Vento models through the 1990s. Includes the used gasket, liner, and cap as shown in the photos.

The valve cover protects the valvetrain components, ensures proper lubrication, and prevents oil leaks. On 30-year-old AAZ engines, covers crack or warp over time — a donor OEM unit is the correct fix.

⚠️ Important Notes

• AAZ engine only. Do not confuse with the 1.9L TDI valve covers (AHU, ALH engine codes) introduced in late 1996–1997 — those have different mounting points and are not interchangeable.
• Verify your engine code before ordering.
