2005 F350 DO I HAVE TO PRIME THE TURBO

[Anson]

I rebuilt the Turbo last nite and cleaned it up, the vanes were stuck. So now im curious if I have to prime the Turbo before I crank it over. or if just running the motor will be good enough. Thanks

the Diesel will actually throw enough oil into the turbo when started, Said thing is I asked a guy from Ford Service and he told me I should dump in to quarts of Oil into the turbo, I found that very odd so went to a very well known diesel company and they laughed and said no way, just the let truck do its thing.

OK, so tell us why not.

I use a socket on a breaker that fits the turbine nut on the intake side. While using the socket on the nut, I have someone else start the truck, I keep the turbo from spinning for about 30 seconds. This allows oil pressure to build and fill the galleys on the turbo without spinning, then let it go.

If you do this I recommend shutting the engine down after the 30 seconds and not removing the socket until the turbine quits trying to spin. I wouldn't want to take a chance on the socket slipping off the breaker and bouncing around in there.

Pre-lubing during assembly should suffice.

Done it many times on bigger engines when I worked in the truck shops. At idle, there is not enough exhaust flow to really spool it up, plus you would not believe how little effort that is needed to hold it.

Same as ehoefler. I make SURE it's oiled

When changing turbo's you should add oil to the supply line hole and spin it by hand so the bearings are fully lubricated.

I've done it both ways.

Both work so I stopped priming them a long time ago. Essentially any time you start an engine with a turbo, it is started dry anyway. Connect the oil line up and light it off.

No, it's not common to do so. The turbo will fill and pressurize with oil in about a second.

[K_Charles]

Did you "rebuild" it or clean it up? If you truly rebuilt it then you know it needs oil before it starts spinning.

[ChooChooMan74]

I think he means turn it over without firing it up to pump oil into it..

[edbehnke]

prime it

No idea how yow you would "prime" the turbo. It just spins on it's own as the gasses flow over the vanes. JMHO
