On the 2010-2023 BMW X6 M S63, the 4.4L twin-turbo S63 V8 in the X6 M (E71, F86 and F96) can wear its connecting rod bearings early. Owners and enthusiast publications report it, but they disagree on how often it happens. One S63 buying guide calls rod bearing wear the most discussed S63 issue. It explains the cause this way: under high heat and long high-rpm running, the oil film on the rod bearings can break down, and long oil-change intervals or the wrong oil viscosity make wear worse. That guide gives typical mileage as 60,000-100,000 miles. Another S63 guide says the problem is "blown way out of proportion" and likely affects a very small percentage of engines, and it also points to poor oiling or poor oil quality as the usual start. Early signs are hard to spot. Copper-colored shavings in the oil are often the only warning before a knock appears. Left unchecked, a worn bearing can lead to rod knock and serious engine damage. We found no BMW recall or service bulletin for this issue.

This issue also affects: BMW M5, BMW M6, BMW X5

Common Symptoms

Knocking or ticking from the bottom of the engine, most audible at idle when warm
Copper-colored metal shavings in the oil or oil filter at an oil change
Oil analysis showing raised bearing wear metals
Rod knock that worsens over time, which can end in serious engine damage if ignored

How to Fix

Check first: at each oil change, look for metal (copper-colored) shavings in the drained oil and filter, and listen for a knock or tick from the bottom of the engine, which is usually easiest to hear at idle with the engine warm. A cheap oil analysis every couple of oil changes can show bearing wear before it becomes audible. Prevention: change the oil every 5,000 miles at most, using a full-synthetic 0W-40 or 5W-40 that meets BMW Longlife-01. Do not use LL-04 oils. Many in the M enthusiast community recommend replacing the rod bearings preventively at about 60,000 miles, especially on the early E70/E71 engines, and before raising power with a tune. The job is optional, since some sources consider it costly for bearings that may be fine. It is labor-intensive, and one guide puts replacing all 16 rod bearings at $2,000 or more. Replacement bearings are OEM, or aftermarket sets such as ACL Race Series 8B1578H-STD, which retailers list for S63B44 engines. Confirm the part number for your engine before ordering. If the engine already knocks, stop driving it and have an S63-experienced shop inspect it, because a failed bearing can damage the crankshaft and engine. When buying a used X6 M, ask for oil-change records and any bearing-replacement history, or get an oil analysis.
