You’ll want to pre‑lube the center section and then crank the truck to build oil pressure before you ever let it light off.
Priming procedure for this turbo-
With the turbo on the bench, pour a little clean engine oil (same oil you’re running in the truck) into the oil feed port while slowly spinning the compressor by hand so the bearings are coated.
-
Install the turbo, oil feed and drain, and all lines, but leave the intake tube off so you can verify the wheel spins freely.
-
Change the engine oil and filter if you haven’t already, and make sure the oil feed and drain lines are clean and not restricted.
-
Disable the engine so it cannot start (unplug the appropriate connectors or disable fuel) and crank the engine in 10–15 second bursts until you’re confident it has built oil pressure and fed the turbo.
-
Reconnect everything, start the truck, and let it idle only for a few minutes while you check for oil, exhaust, or boost leaks—no revving or loading it right away.
That’s all it needs—pre‑lube through the feed, then crank to get oil to it before first fire so the new charger doesn’t see a dry start.
