Assembled By ECS Timing Service Kits | BMW S54 Engines

Your BMW has an interference engine, which means if the timing chain were to fail for any reason, you would have catastrophic engine damage due to valve to piston contact. Over time the timing chain will start to wear and stretch, potentially causing it to skip timing or just completely fail. Also, the timing tensioners themselves could fail! Early symptoms of timing chain wear include front end noise not associated with VANOS, or slapping noises coming from the timing cover.

We have created the perfect solution for you. Everything you need to service your timing chain is included.
