how to prime a fresh rebuild/refreshened engine?

[chris142]

I've also packed the oil pump with vaseline to help prime the oil pump.

I prefer the STP in the blue bottle. It's gooey and sticky enough to let the pump pull oil.

You now have seen that there are as many opinions as posters. I would bet that all have a satisfactory experience starting and running a new engine. I crank it with the FSS disconnected for about 10 seconds. Connect the FSS and let 'er rip. If you took care while building and have assembly lube on most everything, there should be plenty of protection until the oil gets there under pressure. The diesel pumps are high volume, not a lot of pressure, so if they work at all you are covered.

Drag it down the street with the glow plugs out. Being in 1st or 2nd gear will spin the engine fast enough to make pressure quickly. Otherwise just start it up but make sure the oil filter has been prefilled with oil. BTW you can't fill the oil filter completely to the top. It will still because the filter attaches on an angle to the block. Its not level. Having issues believing this. Try filling it and find out.

Yeah, there is. Forgetting to fill or not using enough. Been there. I would rather pour a quart or four on the ground than save one and burn up the engine.

the spelling police has arrived!
please dont beat me mr. officer

 

[sjwelds]

Well I guess waist is still a word at least figured I'd be annoying enough that y'all would know it's me

go weld something lol

Imo spinning the engine over just spins the parts and wipes the oil off. The pump pumps much better at running speeds than it does cranking

that's my thought too.
the quicker she lights up,the quicker she can build pressure.cranking is just spinning without oil pressure.

Oh for cripe sakes.
Brian, when its all set to go, just turn the key and dont worry about it lol. This thread is almost as bad as those ridiculous amsoil debates .

That's why they make assembly lube. In general, if you used a good dose of a high quality assembly lube, it will protect engine parts until oil is distributed via oil pump.
