Hey Guys

I have a 1.9tdi 110bhp and at around 2000rpm there is a noise that comes from the engine, it sounds like it is coming from something that is rotating and at around 2000rpm it is rubbing somthing, it is hard to describe the noise, but it is only at around 2000rpm up to and after there is nothing.....

Just curious as to whether people have had something like this before?

Thanks

Adam

PS: Also coming up to service time and was wondering what oil would be recomended for this engine....
