Just because you have a keyboard
He may be referring to my question about the timing chain. I am not sure if BMW used a chain or a toothed belt in this application. The belt style needed to be replaced every 40k because they normally failed around 50k and took the engine with it if failed at a higher rpm. The original engine in my car died when the timing chain failed at 150k. There must be some normal service requirements for this part. The service requirement for adjusting the balancing chain in my Porsche 944 was 15k and needed special tools. Do it wrong and you can ruin the motor.
I sure hope I can get more than a year out of my serpentine belt. Overall I am happy with the car, cheap to insure and it gets good mileage.
Thanks for everyone's input.
Now I 'm going to check the serpentine belt.
