The crankcase ventilation cap, also known as a breather valve or diaphragm valve, regulates pressure within the engine's crankcase. It allows harmful blow-by gases to escape while preventing contaminants from entering the engine.
This cap is compatible with specific BMW models including the 3 Series (E91, E90, E92, E93), 5 Series (E60, E61), 1 Series (E81, E82, E87, E88), X1 (E84), and X3 (E83), provided they are equipped with the N47 engine.
RIDEX recommends replacing this crankcase ventilation cap every 60,000 kilometers or every 3 years to ensure optimal performance.
The cap measures 80mm in length, 15mm in height, and 80mm in width.
The associated part numbers are 11127797613, 11128508570, 7797613, and 8508570.
While possible for experienced DIY mechanics, installation often requires specific tools and knowledge of engine components. It is generally recommended to have a qualified technician perform the replacement.
A faulty crankcase ventilation cap can cause excessive pressure. Inspect the cap for damage or blockage and replace if necessary, following the recommended interval or if symptoms appear.
Excessive crankcase pressure can affect engine performance. Ensure the ventilation cap is functioning correctly and is not clogged. If the issue persists after replacement, further engine diagnostics may be required.
While not the sole cause, a malfunctioning crankcase ventilation system can contribute to increased oil consumption. Verify the cap's integrity and replace if it's beyond its service life or shows signs of wear.
Compatibility Verification: Before purchasing, confirm that your vehicle is listed among the compatible BMW models (3 Series E91, E90, E92, E93; 5 Series E60, E61; 1 Series E81, E82, E87, E88; X1 E84; X3 E83) and that your engine is an N47. Cross-reference the part number (11127797613, 11128508570) with your vehicle's existing component or consult a BMW specialist.
Installation: Installation involves accessing the crankcase ventilation system, typically located on the cylinder head. This process may require removing other engine components. It is recommended that installation be performed by a qualified mechanic to ensure correct fitting and avoid damage to the surrounding parts.
Care: This is a replacement part and does not require routine maintenance. However, it is designed for a specific service life and should be replaced according to the manufacturer's recommendation (every 60,000 km or 3 years) or if signs of failure are detected.
