BMW Valve Guide Exhaust - Genuine BMW 11121250268

Product Information

A valve guide is a cylindrical component in an internal combustion engine that serves to align and support the intake and exhaust valves as they open and close. The valve guide ensures that the valves operate smoothly and maintain proper alignment with the valve seat for optimal engine performance. They are typically made of durable materials like cast iron or bronze to withstand heat and wear.

• Excessive Oil Consumption: Worn valve guides or seals can allow oil to seep into the combustion chamber, leading to noticeable oil loss
• Blue Smoke from Exhaust: Burning oil due to oil leakage into the combustion chamber often produces blue smoke from the exhaust
• Poor Engine Performance: Misalignment of valves caused by worn guides can result in incomplete combustion, loss of power, or rough idling

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
