Drain oil from top of motor?
Need to fill in my knowledgebase.
If I put the Patrol on it's side or upside down, could oil run into the top of the motor?
If so, does it help if I remove the glow plugs and turn it over to remove the oil?
If so, how do I go about that and do I need any special tools?????
Thanks.

Geez, you're going to need some special tools if you want to turn your Patrol upsidedown! If you want to do it in a controlled fashion that is...

I was born with those tools, feet, arms, hands and deranged mind.

If it is upside down for a long enough period, oil will drain past the rings, into the combustion chamber, past an open valve, into the inlet plumbing. It will also rapidly fill the tappet cover. Once back on its feet, it will drain from the tappet cover, but due to lack of pressure, (oil level) it will mostly stay in the combustion chamber.
Removing the glowplugs; then cranking the engine should clear the top of the pistons. If you don't do that, you risk bending a rod from hydrolock.
You would also have to clear the inlet plumbing. I don't know long it would take to affect the turbo from oil getting past an open inlet valve, though.

Maybe treat it like a fridge? If its been on its side for 2 hours stand it up for 4 before you restart it? .

Thanks Craig. How/why would it affect the turbo? I know the turbo needs oil, wouldn't it just suck oil up as it would normally??

I suspect that if the geometry allowed oil to get to the turbo it would coat the inlet blades, most likely unevenly. I don't know where your EGR is plumbed into the system, but sticky turbo blades and EGR soot aren't a good combo.

And possibly uneven oil coverage on the blades could unbalance the turbo and blade could end up meeting casing???
