Oil Return Tube Cover With Silicone Membrane For Nissan Trafic Vivaro

Fuel pressure stability and clean valve operation rely heavily on an intact oil return system in modern common-rail diesels. This Oil Return Tube Cover with Silicone Membrane bridges that gap, featuring a durable PA66+GF30 polymer housing paired with a resilient silicone diaphragm to keep the crankcase ventilation circuit leak-proof under constant thermal stress.

Designed specifically for the 1.5 dCi and 2.0 dCi/CDTI engines used across Nissan and Renault platforms, the unit restores proper backpressure without restricting airflow. The hermetically sealed construction prevents external contaminants from entering the intake tract while efficiently routing blow-by gases back into the combustion cycle. Compact dimensions allow quick installation behind the inlet manifold, eliminating persistent oil mist leaks that often trigger false sensor readings and reduce fuel efficiency.

Benefits & Practical Tips

• Always cross-check the stamped identification code on your existing unit against the provided OE numbers before ordering, as platform revisions frequently change sealing profiles.
• Clean carbon deposits from the cylinder head mating surface with a non-abrasive plastic scraper to guarantee the silicone membrane seats evenly and maintains consistent actuation pressure.
• Avoid overtightening the retaining bolts during reassembly, which can distort the diaphragm and prematurely compromise the vacuum seal.

Installation Warning

This assembly serves as a direct hardware replacement for diesel emissions management circuits. Because production batches vary across manufacturer lines, confirming an exact part-number match with your original component is required for safe operation. Follow factory torque specifications and inspect surrounding hoses for degradation before final reassembly.
