As far as I know, the pan has never been off.
The truck did not have this problem whae I first bought it. I first noticed it after I changed to 10w40 oil. I will be sitting in traffic and the gauge will strrt to go down, and the enging will start rattleing and just when I think I thougd shut it off, the pressure will come back up and it will be fine. It was a little bit worse the last time it happened though. So do you thing oil pump problem, or is it time to re build the engine
