can you increase the oil pressure on q 1925 dodge brothers touring by stretching the spring which is with the steel ball in the oil tube where you prime the engine if need be.
and making sure the ball goes down first then the spring?

Yes, but why. If it has pressure it has enough. It's not like a modern car that needs 30 lbs.

Guys, NO you cannot 'Up the oil Pressure' by fiddling with that spring and ball. That spring loaded ball valve is there simply to prevent the oil in the dispersal tube in the block from draining back to the pump and creating air in the line so when starting the next time there will NOT be fresh oil to that dispersal tube to fill those recesses in the plate on top of the oil pan for the rods to dip into and get their lube. The Dodge Brothers oil system is NOT a pressurized system. The oil pump simply gets the oil up from the pan to that oil dispersal tube inside the engine to spray into recessed channels for each rod cap projection to dip into to lube the rod bearings. The main bearings are lubed by the 'Splashing' oil around inside the engine when running and keeps title reservoirs on the main crank bearing supports filled. This is referred to as a "Dip - splash" oil system.

Just an additional observation. If fiddling with that spring does happen to resist oil from the pump getting up to the engine dispersal tube, please observe that 'Y' below that fitting where the oil pressure gauge pipe heads rear of that fitting. The ONLY thing you will observe on the pressure gauge is the result of diverting the oil from where it needs to go and the result will be an 'Artificial' reading of increased pressure!

Miles;
Do yourself a favor and buy the DB Mechanics' Instruction Manual.
It contains the answer to most every question you've ever asked and those you will be asking in the future.
However simple these contraptions seem to be there are details that even the most experienced mechanic or engineer could not know without referring to the original manual.
