Description

The Genuine PACCAR Crankcase Ventilation Breather is an oil separation module for PACCAR MX-13 12.9L diesel engines. It removes oil mist from crankcase gases, returns separated oil to the engine, and manages crankcase ventilation flow. This helps reduce oil contamination in the intake system, maintain proper crankcase pressure, and support emissions-system operation.

Purpose of the Part

The 2419493 separates oil droplets from blow-by gases produced during engine operation. The recovered oil returns to the engine, while filtered crankcase gases pass through the ventilation system. Proper operation helps control crankcase pressure, reduce oil carryover, and protect intake components from excessive oil contamination.

Issue Symptoms / When to Replace

A failing crankcase breather may cause:

- Excessive crankcase pressure.
- Engine oil leaks or increased oil consumption.
- Oil accumulation in intake piping.
- Check Engine light or crankcase ventilation faults.
- Excessive oil mist from the breather outlet.
- Unusual noise or vibration from the breather assembly.

Similar symptoms can result from excessive engine blow-by, restricted ventilation lines, or a clogged serviceable filter.

Brand Information

PACCAR manufactures MX-series diesel engines for Kenworth and Peterbilt trucks. Its crankcase ventilation systems include Hengst-manufactured modules and later Cummins-supplied configurations. Both designs separate oil from crankcase gases, but their filter service requirements differ.

Installation Notes

Before installing the crankcase breather, inspect the ventilation hoses, oil return passage, and electrical connections. Replace required seals and confirm the correct mounting and filter configuration. Check for oil leaks and proper crankcase ventilation after installation.

How to Identify an OEM Part

The Genuine PACCAR Crankcase Ventilation Breather can be identified by the factory label displaying the PACCAR logo, part number, and 12V rating. The label also features EnviroGuard branding, a maintenance-free designation, manufacturing information, and a 2D Data Matrix code for traceability.
