Hello All
I am new to this forum and wonder if anyone out there can help me.... I have got a 2001 Disco 2 TD5 GS with 197000km on the clock. When I start it up, it sounds OK at all engine rpm's. However, when its reached operating temperature - which happens with-in 5 kM , with temperature needle sitting at a 3 o'clock position - a rattle can be heard at idle (800rpm). This rattle disappears at 1100rpm. Any ideas? I have changed all filters, and oil (Castrol Edge 5W-40W).

Thanks
Jerry
