New Injectors

[Mikes7.3]

I installed new injectors, I pulled all the glow plugs and turned the engine over by hand to make sure the cylinders don't have oil in them. I reinstalled the glow plugs and put everything except the valve covers on, and turned the engine over again by hand 4 times.

My question is if oil is still in the cylinders how hard will it be to turn over by hand. I haven't tried to turn it over with the ignition yet. I want to make sure there isn't any oil left in the cylinders.

I am not sure that arms are strong enough to do that. If you have the new injectors in and the glowplugs out, spin it with the starter motor, be sure that you have the valve covers on with two screws as the oil that is displaced will squirt 30 feet into the air.

STOP!

Take the glow plugs out and you can take the valve covers off.

Turn the motor over with the key between 10-15 times to purge the cylinders of oil. I have a video of this somewhere's...
Then crank on it for a few seconds a few times, reinstall the g/p's and valve covers and start it. It will be hard to start, have a battery charger available. It'll run rough for a few miles then clear up.

Turning it over by hand just doesn't give the oil enough velocity to make it out of the cylinders.

Here is how I did it.

I'm asking if oil is in the cylinders with everything on would I still be able to spin it by hand.

Either use the starter method the the key method with the GP's out.

Funny thing happened, I was so concerned about hydro lock, that I had it all together Sat night.

I've been working on my truck since Wed. I installed new bellowed up pipes,high flow outlet,non ebv pedestal,ITP Regulated fuel system,Air Dog fuel prep,and the injectors.( after pulling glow plugs and turning it over to purge the cylinders)I put it all together, I go to start it up and all I get is a ugh hardly turns over, (I'm hatin life right) so I take it apart again and pull the glow plugs turn it over to clear the cylinders put it all back together again and I get the same thing again.

This is the funny part, if you have a warped sense of humor:

The batteries were dead from testing the new fuel system.

Now that's funny.
