White smoke after a few min

Re: White smoke starts to we'll up under engine after running for a few minutes

I got the engine back together and now it's reving slow and not turning over. At first I noticed the fuel injectors were leaking so I tightened them. Still having same issue. Is there something I might have missed putting it back together?

New head gasket?
Valves adjusted to specification? Does That gasket require an o-ring on one tube that sticks out of block?

Battery fully charged ?
That one use a decompressor?
Injectors bled?

You say, "...it's reving slow and not turning over."

Reving refers to revolutions, which is turning over. So how can an engine be reving but not turning over?

Are you meaning to say the engine is turning over but not starting?

Do you have enough battery to turn fast enough? Bleed injectors until no air bubble are visible.

The engine will rev but will not actually start. Sorry I'm not familiar with all the terminology. I thought you bleed the lines if the engine comes on and runs for a few minutes and shuts off?

You have to bleed the lines of all air before the engine will start.

When you removed the head you also removed the fuel lines from the injector pump to the injectors in the head. Those lines now have air in them, which needs to be removed.

Do a search on how to bleed the fuel system on a Kubota diesel engine.

Basically, you need to have a good charge on your battery. Have fuel lines connected. Let air out at your fuel filter, then at the injection pump, then at the injectors.

Don't let the starter run more then 15-20 second intervals and give a 20 second cooling off period after two or three of those 15-20 second intervals.

When you no longer have some bubbles (but fuel only) coming out at the line where you loosened the nut on top of the injectors, you can tighten those nuts and it should start.
