I own a 1999 BMW 740IL. It’s been a long time dream to own this classic luxury automobile. In the process of searching for it, I learned many, many technical details about this series of BMW, including the common issues and their complexities. While purchasing my vehicle, I was aware right up front that the engine is emitting a noise which suggesting the timing chain guides are broken. Although this is not any catastrohic failure, the timing is looser than spec and does present a risk. I planned right from the beginning to replace the timing chain guides, and any other issues which are present during the rebuild.
This page will serve as my write-up on the entire rebuild process. If you don’t see any pages linked below, I haven’t started yet.
