058 103 213 – Crankcase Breather Tube

Description

The 058 103 213 crankcase breather tube is a rigid plastic pipe that forms a central part of the engine’s ventilation circuit. This tube carries oil vapors and blow-by gases from the crankcase to the PCV system, allowing the engine to relieve internal pressure efficiently.

Hard plastic pipes are common in modern engine bays, but they are inherently susceptible to aging. Years of exposure to intense engine heat and varying weather cycles eventually make the material brittle. Consequently, the tubing can develop hairline fractures or snap entirely, leading to significant system leaks.

Why the 058 103 213 Crankcase Breather Tube Matters

A sealed ventilation path is essential for maintaining correct engine vacuum and emission standards. When the 058 103 213 crankcase breather tube cracks, it introduces unmetered air into the intake tract. This disruption causes the engine management system to struggle with air-fuel calculations, often resulting in poor performance and idling issues.

Replacing a compromised breather tube with an OEM-quality unit restores the airtight integrity of the crankcase. By ensuring gases are routed correctly, you protect engine seals from pressure-related failure and keep the intake system free from excessive contamination.

Signs Your Crankcase Breather Tube Needs Replacing

Monitor your vehicle for these indicators that the ventilation tube has failed:

• Rough or unstable engine idle.

• Check engine light (CEL) indicating lean-run or vacuum-system codes.

• Visible oil seepage or “sweating” on the exterior of the plastic pipe.

• Brittle texture that breaks easily when touched during other repairs.

• Hissing or whistling noises coming from the lower intake area.

• Notable decrease in fuel economy and throttle response.

When one part of the breather system fails, other plastic and rubber connectors are often in similar condition. Therefore, it is recommended to inspect the entire PCV assembly whenever you identify a crack in the main tube.
