Hi I've just bought a 2012 1.2 500 for my boy, I've been doing some servicing and have just replaced the timing belt, tensioner and pump as it has no history but it's now making a fairly loud whirring noise. I've disconnected the aux belt so it's not the A/C pump, alternator etc and when I put a long screwdriver to my ear the sound seems to be coming from the oil pump not the water pump or timing belt or covers . It's been up on axle stands for over a week so would the oil pump have draind down? Any suggestions?
Thanks.
Thanks.
