Hi guys!
I`m discussing the oil lubrication system on the Nytro in a Norwegian forum and I need to know a few things.
I recently rebuilt dimebags engine so I should know how it works but I don`t feel 100% sure.
My understanding is that the oilpump gets its oil from the oil tank through the hose/channel in the block. The pump also sucks oil from the oilpan but this is to get the excess oil back into the oiltank-system because the oil will flow down from the head and the pistons. Am I right?
But, does all the oil that returns to the tank come from the two oil intakes in the bottom of the oilpump? Or does the oil that lubrcates bearings etc. return to the tank combined with the "return" oil from the pump?
So in other words you can say that the pump has two functions?
I feel like an idiot since I don`t know this but you learn as long as you live
Would be awesome if someone could say a few words on this.

A. Yes this correct. Once the oil has completed its lubrication and cooling functions, All of the oil gets savaged and returned to the oil tank.
But, does all the oil that returns to the tank come from the two oil intakes in the bottom of the oilpump? Or does the oil that lubrcates bearings etc. return to the tank combined with the "return" oil from the pump?

A. Yes oil pump serves two functions. Pressure or supply and return or savage. Normally the savage rate is slightly higher then the supply rate. This helps ensure that the oil supply will stay in the oil tank (to supply the oil pump), instead of in the bottom of the crankcase. Once the oil has drained to the bottom of the crankcase, it no longer serves a purpose (other than some heat transfer/cooling). So the oil needs to been returned/savaged and pumped back to the oil tank as quickly as possible.
All oil used for lubrication is drawn from the oil tank.
When the oil is savaged/returned to the tank, air can be mixed with the oil due to various reasons such as blow by gases, suction ports exposed to air during rough riding, rapid RPM changes, high savage rates, etc. When the oil/air is returned to the oil tank, the air and oil are seperated by either using an air/oil seperator (Apex, Vectors) or placement and shape of the return port in the oil tank (Nytro/Phazers). This insures that there is no air mixed with the oil after the savaging process.
Once the air/oil have seperated with in the oil tank, the whole process starts over again.

Great guys! Thanks! Awesome!
When is the oil filtered? Before it lubricates?
And it runs through the oilcooler when it is on its way back into the oiltank? Or?

Yes indeed, the oil gets filtered before flowing to the lube galleys.
Not 100% sure about at which point it passes through the cooler though. Typically the oil will pass through the cooler before flowing to the lubrication points. This helps the oil cool the internial componets.
One of the main purposes of the oil that most guys don't think about, is that oil also cools the engine by transfering heat away from moving parts.
