035 103 245G – Breather Valve (PCV)

Description

The 035103245G PCV Valve is an OEM-quality breather component for the positive crankcase ventilation system. It controls crankcase gases and directs them back into the intake system for combustion. Consequently, it helps reduce pressure buildup, oil vapor accumulation, and unnecessary emissions.

This valve supports stable engine operation by allowing the crankcase ventilation system to function as intended. Moreover, its heat- and oil-resistant construction helps provide dependable service in demanding engine-bay conditions.

Why Crankcase Ventilation Matters

During engine operation, combustion gases can pass into the crankcase. Therefore, the PCV system must control and recycle these gases safely. Without proper ventilation, internal pressure can increase and force oil past seals or gaskets.

Furthermore, excessive crankcase pressure may contribute to oil leaks, increased oil consumption, and poor engine operation. Replacing a damaged breather valve helps restore proper ventilation and supports a cleaner engine bay.

Signs of 035103245G PCV Valve Failure

Inspect the crankcase ventilation system if you notice any of these common symptoms:

• Rough or unstable engine idle.

• Increased engine oil consumption.

• Oil seepage around engine seals or gaskets.

• Whistling, hissing, or air-leak noises from the engine bay.

• Check engine light related to air or fuel mixture concerns.

• Reduced fuel efficiency or hesitation during acceleration.

• Excessive oil vapor inside intake components.

Service Notes

Always verify fitment by VIN before ordering. Before replacing the valve, inspect connected breather hoses, fittings, and intake connections for cracks or loose clamps. Additionally, check for oil contamination or hardened rubber components in the surrounding ventilation system.

Compatibility

Always verify fitment by VIN before ordering. Fitment depends on engine code, model year, crankcase ventilation layout, and original installed part number.
