Hello everyone, I just acquired my first Discovery last thursday. I am new to the site, and although there are a few threads that somewhat address my issues, nothing I have found has been specific. So, please excuse the repetition: I am experiencing a rattling sound. It can be heard best from the left side underneath the front of vehicle. It seems to come from just past the exhaust manifold. The sound is muffled if I take a screw driver and pry the pipe slightly from underneath the vehicle. The rattling ony presents when the vehicle warms up; after about 5-10 minutes of driving. It is engine rev dependent, it seems to speed up with the engine and is louder on take off. Can anyone point me in the right direction? Thanx
