ok heres the problem...when i start my car theres no noise when just idleing but when i start to drive theres a weird knocking type noise that goes away after only about a minute of driving if that. But it only makes the noise when i first start driving.
If anybody has any clue what this is, please help me out....Thanx.

Out of size bearing? Like rod knock? When the car heats up the beaing expands and the noise goes away. My opinion.
