Well I just resently started hearing a cracking noise comeing from the bottom of my truck sometimes when I first start it up not all the time but as soon as I start it up you can hear the noise and then it go's away I think it might be the oil pump bcus when my mechanic did the last oil change and he started the engine the truck made the same noise but for a longer period of time..so just wondering if it is the oil pump or if it is something else.. Thanx for the help
