Hi all, so after changing the timing chain and coolant pump, the engines lovely and quiet now so quiet I've noticed another noise ! So when the car is in nutural, it's like a tapping noise/bearing, but I can only hear it in nutural, push the clutch in and this noise disappears, it had a new clutch kit fitted last year , done a bit of googling and think it's a input Shaft bearing, so i figured this first and easiest thing I could do would be to change the transmission oil, because it might not of been changed for 120k miles, I'm not sure if A1 clutches use the same stuff they drain when doing the clutch hell I'm not even sure if you have to drain it to do the clutch, but I'd imagine they would reuse to save money as it's 15 quid a litre, is this something that may help anyone else think it's worth a try? Thanks again all.
Just pulled this from Google
A worn or defective input shaft bearing can cause noisy operation in neutral with the engine running. The pitch or tone of the noise changes with engine speed and a slight vibration might be felt through the shifter. This symptom can also be caused by deficient gear oil levels or quality.
Thanks
Mike
