If you think there's no oil pressure until the oil hits the bearings you are just so wrong.
The only reason I put a red X on there is because I disagree with you.
fluid pressure. noun. the pressure exerted by a fluid at any point inside it. The difference of pressure between two levels is determined by the product of the difference of height, the density, and the acceleration of free fall.
Every turn of the passage every downsize of the passage causes resistance which builds pressure. If it comes to an open area then the pressure drops.
How about we get back to solving this guy's problem instead of discussing this plug.
