Typical symptoms of worn connecting rod bearings
Listen for knocking or metallic noises from the engine, especially when cold, as well as sudden drops or insufficient oil pressure. Other warning signs include metal shavings in the engine oil or oil filter, loss of power, rough running, and in extreme cases, even engine stalling while driving.
Welche BMW Modelle sind besonders betroffen?
BMW M3, M5, and M6 models with high-revving V8 or V10 engines are particularly prone to this issue. For these vehicles, Friedrich AMS recommends preventative connecting rod bearing replacement after a certain mileage to avoid costly engine damage.
Our connecting rod bearing service at Friedrich AMS
● Professional diagnosis in case of suspicious noises or oil pressure warnings
● Disassembly, inspection and replacement of connecting rod bearings and bearing shells
● Cleaning of the oil circuit, oil change with high-quality engine oil
● Optional combination with other engine work (for example, timing chain, oil pump)
If your BMW is rattling, the oil pressure is too low, or you drive a known problematic model, we will give you honest advice on whether a preventive connecting rod bearing service makes sense before wear and tear leads to engine damage.
