Hi all this is my first post here. I just finnished driving from galveston tx to las vegas nv it took 30 hrs streight through, I let the truck sit overnight and when I started it in the moning it was blowing large amounts of white smoke and running very rough, it cleaned up and began running as it should after 4 blocks. Oil looks good as I changed it and the filter just before the trip, radiator is still full, fluid is clean and no bubbles, so I would rule out the head gasket. I've had the truck about 8 months and put 8000 on it in that time. this is the first time this has happened. Any sugestions as to what might be causing this?? . I'll see if it does it again today after sitting all night and report back.
Thanks
Robert
