James's point is correct, except that for the first time you start it up after a rebuild, you do have to make sure that the oil pump is totally primed (filled with oil). |

Gentlemen, pardon the expression, but this is "...like pissing in the ocean trying to raise the tide." I assume that during assembly all moving parts were oiled. Consequently, starting this new engine is no different than starting an old engine. Within seconds pressure is achieved through the normal oil pump process. Oil used during assembly will stay there for years, and will protect the moving parts for the few seconds until pressure is achieved. At the most, turning the engine over with sparkplugs removed will accomplish everything you desire, and that is what I have done in the past when starting engines that I have built. Much to do about nothing.

1. Lubed the parts during assembly
2. Connect the oil radiator
3. Fill the oil pump from the top with one of the oil radiator connections open
4. Connect starter, battery, and hand starting device
5. Connect a DVM to the oil pressure gauge
6. Crank the starter until the oil pressure shows a voltage
7. Continue for another 30 seconds or so, or more if you like, the motor is now oiled.
That is what I did. |

You can maybe rent a machine from an engine shop.It aint nothing fancy. You need air pressure to push the oil in. when it is complete you will see it come up the cam holes. Never did a fCAR engine but have done it on several US v-8's. on them u will see the oil come up and pour out of the pushrods and back down. I hook up where the sending unit attaches. It is the only way to go.
spinning the engine with starter will cause wear .All u have is assembly lube on most of the parts. |

Hanz, I just did a rebuild on my 308 and what I did was first pour oil down where the oil filter connects. there are two holes, the one that gos to the cooler is most important since it will fill up the passages from the oil pump. Then pull the plugs and crank at 10 sec intervals, mine only took 3 or 4 times before it was primed. Even after you show psi do a few more times because your gauge gets pressure first, you need some time for the oil to hit the cams

I've seen pre-oiler gizmos that basically plumb into where the oil pressure gauge goes. Air pressure forces oil out of an external tank into the gauge fitting. |

-- but take the spark plugs out to ease the load on the starter motor. |

Take the coil wire(s) off, so the engine can't start, and run the starter a minute or so. Any respectable rebuilder would have lubed the critical parts, so it's not much of a worry. |

I couldn't find a thread on this topic when I searched, but I want to pre oil pressurize my new motor before starting it. I'm assuming you need to use air pressure to get oil to the various places in the motor What do I need to do?
I've been told it's a good idea to make sure that all the parts are pre oiled before installation and starting it up.
What is the best way to do this?
