Description and Purpose:

This Genuine Paccar Crankcase Ventilation Module, Part number: 2159858PE, comes in new condition and is built to meet EPA 2013 standards for emission control. Designed for MX-13 engines, it fits a wide range of Kenworth models like T660, T680, T880, and W900, as well as Peterbilt trucks including 365, 367, 386, 388, 389, 579, and 587. This module actively removes crankcase gases to maintain optimal pressure and reduce oil contamination. Cross reference: 2159858

Why Replacement is Important:

A clogged or degraded module can increase crankcase pressure, leading to oil leaks, sludge buildup, and sensor malfunction. Replacing it prevents these issues and supports long-term engine reliability.

Impact on Vehicle Performance:

With proper ventilation flow, engine operation remains consistent under load, fuel economy is stabilized, and harmful contaminants are reduced before re-entry into the intake.
