I just installed a rebuilt turbo. Before I put it on I poured oil in the oil holes and turned the impeller shaft to work the oil into the bearing. A buddy of mine told me he primed the turbo on his kenworth by sticking a pencil in the impeller wheel to keep it from turning for about a minute while he started his truck in order to get oil to the turbo. He was told that if he didn't do that he might burn the bearing on startup. He talked to a ford mechanic down the street and he said I could do this or I could just start it. Well I tried to stick a pencil in there to keep the wheel from turning but it damn near ripped the pencil out of my hand when it started so I wasn't able to do this. I let it run anyway and everything seems fine. Drove it a few miles and there doesn't seem to be any problems. Does anyone have any ideas on this? Could I have caused some damage to my expensive new turbo?
