Today at Zia Autohaus, we're tackling a major repair on a BMW X5 50i. The vehicle came in with excessive oil consumption and smoke coming from the exhaust, and after diagnosis, we determined the culprit was worn valve stem seals.
We're replacing the valve stem seals to stop oil from entering the combustion chambers and restore proper engine operation. This is a labor-intensive repair, but it's essential for correcting oil-burning issues and keeping these V8 engines running strong.
Whether it's routine maintenance or complex engine repairs, our team is committed to finding the root cause and getting the job done right.
