ok heres the deal....i have an 06 duramax.....in the morning when i start her up she puts out a little white smoke and then eventually not too much after that it goes away......next....also when i start the truck up in the morning the oil pressure goes to 60psi and then when the truck warms up when i let it idle the oil pressure goes back down to 30psi....but when i drive its back at 60psi is that bad? lastly....my front end has a little bit of a clank in it when the tires are articulating and what not i can hear a little noise and feel it in the steering wheel....any help would be great thanks so much guys :help
