Mann Filter C 105 Engine Blocks

Mann Filter C 105 Engine Block Crankcase Breather

The Mann Filter C 105 is a high‑performance crankcase breather filter designed to protect the engine block of select Volvo models, particularly the 850 series. It replaces the original factory unit with an upgraded filtration system that ensures cleaner oil, reduced emissions, and extended engine life.

Key Features

• Premium Filtration Media: Utilises a multi‑layered filter core that captures fine particulates while maintaining optimal airflow.
• Durable Construction: Made from reinforced polypropylene housing, the filter resists abrasion and temperature extremes typical of crankcase environments.
• Seamless Fitment: Engineered to match the exact dimensions of the Volvo 850 crankcase breather opening, guaranteeing a snug seal without modification.
• Low Pressure Drop: Maintains engine breathing efficiency by allowing unrestricted venting of blow‑by gases.
• Long‑Lasting Performance: Designed for extended service intervals, reducing the need for frequent maintenance.

Compatibility Overview

The C 105 filter is specifically tailored for the following Volvo models and engine configurations:

These models share a common crankcase breather design that the C 105 filter precisely matches.

Installation Guide

1. Preparation: Ensure the engine is cool and disconnect the battery to avoid accidental electrical contact.
2. Locate the Crankcase Breather: On the Volvo 850, this is a small vent located near the rear of the engine block, typically covered by a plastic cap.
3. Remove Old Filter: Unscrew or unclip the existing breather cover. Carefully remove any debris or old filter material.
4. Insert C 105 Filter: Place the new filter into the vent opening, aligning it with the mounting tabs. The filter should sit flush against the engine block.
5. Reattach Cover: Secure the breather cover back onto the filter. Tighten any screws or clips to ensure a leak‑free seal.
6. Check for Leaks: Start the engine and observe the vent area for any signs of oil seepage or air leaks. Adjust if necessary.

Performance Benefits

• Improved Oil Quality: By filtering blow‑by gases before they re-enter the crankcase, the filter reduces contamination of engine oil, preserving its lubricating properties.
• Reduced Emissions: Cleaner venting lowers hydrocarbon emissions, helping vehicles meet stricter environmental regulations.
• Enhanced Engine Longevity: Consistent filtration mitigates wear on internal components such as pistons and bearings.
• Maintenance Convenience: The filter’s robust design allows for longer intervals between replacements compared to standard breather filters.

Material & Build Quality

The C 105 features a polypropylene housing that offers excellent resistance to oil, heat, and mechanical stress. The filtration media is composed of a layered blend of synthetic fibers engineered for high capture efficiency while maintaining low pressure drop.
