If you own a BMW equipped with a newer V8 engine you may have heard of BMW valve stem seals leak. BMW has been known for award-winning engine designs for the last 20 years however certain repair and maintenance flaws have been revealed with real-world testing by owners like yourself. This article aims to help you understand valve stem seal leaks and if you need BMW valve stem seal repair.

What Are The Symptoms?

BMW v8 engines made after around 2004 have been plagued with a problem where the valve stem seals will leak over time. These engines can be identified by their designation and the “N” in the beginning of them such as the N62, N63 and N63TU engines that are equipped in BMW 5 series, 7 series, X5, and X6 models.

There are several symptoms and consequential problems that arise from stem seal leaks. One of the most common is higher oil consumption from the engine. You may find yourself needing to add oil to your engine. Much newer BMW’s will have an onboard indicator every time the vehicle detects low engine oil. Another common symptom is blue-white smoke out of your tailpipe. This indicates that oil is getting past your valve stem seals and leaking into the combustion chamber and burning up. When the leak is very bad, your vehicle may produce billowing smoke at idle or in traffic. You may also smell burning oil from your tailpipe and the smoke coming from the exhaust may smell.

Leaking BMW valve stem seals can have a snowball effect and cause consequential damage. One expensive repair may be your catalytic converters. As oil is being burned it must pass through the catalytic converters and eventually over time may clog them to the point of needing a replacement. This will cause the check engine light to illuminate. Due to the strict emissions standards, only quality BMW part replacements are recommended.
