FAQs
What is a crankcase breather and why is it important?
A crankcase breather, also known as an oil separator or crankcase ventilation valve, is a component that allows gases to escape the crankcase while preventing oil from escaping with them. It's important for reducing internal engine pressure, preventing oil leaks, and ensuring cleaner emissions by filtering oil mist.
Which BMW models is the Gates EMH938 compatible with?
The Gates EMH938 is compatible with specific BMW 1 (E87) 118i models (07/2004-02/2007 and 10/2006-06/2011) and BMW 3 (E90) 318i models (09/2005-08/2007), particularly those with the 2.0L N46B20B engine. Always verify fitment with your vehicle's specific details.
How do I know if my crankcase breather needs replacing?
Symptoms of a failing crankcase breather can include rough idling, increased oil consumption, oil leaks from seals, or illuminated check engine lights related to emission system faults. You may also hear whistling or hissing sounds from the engine bay.
Can I use this part if my vehicle is from a 'cold climate zone'?
The product information indicates that some compatible BMW 1 (E87) models are not for cold climate zones. It is essential to check your specific vehicle's requirements and consult product details or a specialist if you are unsure.
What is the difference between this and an OEM part?
The Gates EMH938 is designed to meet or exceed the specifications of the original equipment (OEM) part it replaces (BMW 11617526654). It offers comparable performance and fitment as an aftermarket alternative.
What material is the Gates EMH938 made from?
The Gates EMH938 Crank Case Breather is made from durable plastic.
Troubleshooting
Engine running rough or misfiring.
Check for vacuum leaks around the crankcase breather and associated hoses. Ensure the breather is correctly installed and all connections are secure. A clogged or faulty breather can cause these symptoms.
Oil leaks from engine seals or gaskets.
Excessive crankcase pressure can cause oil leaks. A faulty breather may not be relieving pressure correctly. Inspect the breather and replace if necessary. Also, check for blockages in the system.
Increased oil consumption.
A damaged or malfunctioning breather might allow excessive oil to be drawn into the intake system. Inspect the breather and its connected components for damage or leaks.
Part does not fit the vehicle.
Re-verify vehicle compatibility using the make/model tool or by contacting customer support with your vehicle's specific details (year, make, model, engine size). Ensure the correct part number is being referenced.
