Mercedes-Benz Crankcase Breather Cap

This URO engine crankcase breather cap is a direct-fit replacement for Mercedes-Benz applications that use part number 2780100431. It is built to restore crankcase ventilation performance on models such as the Mercedes-Benz S550, E550, and GL550.

  • Direct replacement for the original crankcase breather cap
  • Helps replace plugged or sticking crankcase vent valves
  • Supports proper air/fuel ratio by routing vapors from the crankcase into the intake
  • Helps reduce oil buildup in the intake tract
  • Manufactured to OE dimensions for fit and original appearance
  • Heat- and vapor-resistant valve materials

Detailed Product Overview

URO 2780100431 is an emission control hardware component designed for Mercedes-Benz crankcase ventilation service. By replacing a worn or restricted breather cap, it helps maintain normal engine breathing and supports smoother operation when the original valve is no longer sealing or flowing correctly. This part number 2780100431 is listed for a wide range of Mercedes-Benz V8 applications, including the S550, E550, CLS550, GL550, and SL550.

This part cross-references URO-016043 for the same application.

What It Helps Address

  • Crankcase vent valve sticking or plugging
  • Excess oil residue in the intake system
  • Improper crankcase vapor evacuation
  • Rough engine performance related to ventilation restriction
  • Air/fuel ratio issues caused by a failing breather cap

Installation Notes

Verify the OE part number and vehicle application before installation. This breather cap is manufactured to OE dimensions for straightforward replacement and original-style fitment. Confirm the existing crankcase ventilation component matches the original design on your Mercedes-Benz before service.
