BCBC V3322S Engine Exhaust Valve

Engine Exhaust Valve Overview

The Melling V3322S is a standard replacement engine exhaust valve built for precise fit and consistent valve-train operation. It is made from steel with a coated finish and is engineered for applications that demand heat resistance and fatigue strength.

Compatible with Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman applications, this exhaust valve is a fitment-based replacement for select engines across the listed model years. The V3322S part number is also useful when matching an exact replacement during engine service.

Key Features

• Steel construction for strength in exhaust-valve service.
• Coated finish for added surface protection.
• Standard replacement design for OE-style service work.
• 45-degree seat angle for proper valve seating.
• 0.195 in stem diameter and 0.988 in valve head diameter.
• 3-groove stem design for compatible retainer and lock engagement.

Detailed Description

Melling V3322S exhaust valves are manufactured with controlled materials and processes to meet the dimensional and durability demands of engine rebuilds. The steel body, heat-resistant construction, and coated surface support dependable exhaust-valve performance where consistent sealing and long service life matter. The V3322S is a practical choice for technicians replacing a worn or damaged exhaust valve in select Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman engines.

This part cross-references DNJ (e.g., EV827) for the same application.

What It Is Used For

• Replacing a worn exhaust valve during engine repair.
• Restoring proper valve sealing after valve-train wear.
• Addressing compression loss related to valve damage.
• Correcting exhaust-valve issues caused by heat and fatigue.

Installation Notes and Tips

Verify stem diameter, valve head diameter, seat angle, and overall length before installation. Confirm compatibility with the cylinder head and related valve-train components for the specific engine application. Professional machine-shop inspection and valve-seat service are recommended during engine rebuild work.

Quality Assurance

Melling designs exhaust valves with high-fatigue-strength materials, heat resistance, and manufacturing controls intended to meet demanding engine specifications.
