Restore proper crankcase ventilation with this OEM-spec vent pipe (part 7438487 / 16137438487) — a critical breather hose used in BMW 3 Series and 4 Series models. Equipped with a built-in dust filter, this pipe ensures that crankcase gases are safely routed while preventing contamination. Over time, the original plastic pipe can degrade and become brittle, causing whistling sounds or vacuum leaks. Installing this replacement helps eliminate those common issues and improves reliability in your PCV (positive crankcase ventilation) system.

🔧 FAQs — BMW Vent Pipe 7438487 / 16137438487

1. What is the purpose of this vent pipe?
This is a crankcase breather pipe: it vents gases from the engine’s crankcase back into the intake system or other ventilation paths, helping to regulate internal pressure and reduce emissions.

2. Which BMW models is this part compatible with?
This specific vent pipe (7438487 / 16137438487) is used in various BMW models — for example, some 3 Series Gran Turismo (F34) variants.
Because part compatibility can be tricky, we always recommend checking with your VIN, engine code, or current part to double-check fitment.

3. What are common symptoms of a failing vent pipe?

• A high-pitched whistling or hissing noise from under the bonnet, especially on acceleration.

• Visible cracks or brittleness in the plastic hose.

• Oil mist or residue around the pipe or at connection points.

• Poor engine idle or vacuum leaks (crankcase pressure imbalance).

4. Why is there a dust filter in the pipe?
The dust filter helps prevent dust and other contaminants from entering the crankcase ventilation system, protecting engine internals and maintaining system efficiency over time.

5. Is this difficult to install?
Not particularly:

• The old pipe can be unclipped or unclamped from the valve cover and intake.

• Simply attach the new pipe in the same orientation and secure all fittings.

• After installation, it's smart to visually inspect for any leaks or misalignment.
  Many users note that these hoses are relatively easy to replace but become brittle over time, so be gentle when removing.

6. Will replacing this fix a “whistling” noise I hear from the engine bay?
Yes — a common cause of whistling is a cracked or leaking breather pipe. By installing a new, intact vent pipe, you often eliminate that sound.

7. Are there any known recalls or issues related to this system?
There have been recalls around BMW’s PCV system, particularly relating to certain crankcase ventilation components. While this doesn’t necessarily apply to every model/year, it’s worth checking if your vehicle is affected.

8. Should I replace any additional parts when I change this pipe?
Yes — consider:

• Replacing o-rings or seals where the pipe connects to the engine or intake

• Inspecting other ventilation hoses and PCV components for wear

• Doing a smoke test (or visual check) after fitting to ensure no leaks remain
