It gets burned. Probably has something to do with cylinder pressure and the piston rings.  

Within the catacombs under Jerusalem, they have found jars containing oils over 2,000 years old...
Imagine that...

I forgot the question...

I am not entirely sure where the oil goes - but as the engine load and rpm increase....so does the blow by and oil consumption.  (Ever watch the breather hoses on those pulling tractors?  Nothing much is coming out of the breather when they are idling around and hooking up - but once they get under full throttle there is all kinds of smoke belching out of the breathers).

I think the same thing happens on the Savage.  At low rpm and low throttle setting the pressure in the cylinder is not all that high and there is very little that blows past the rings.....there is very little pressure in the crankcase and very little flow out the breather tube.  When you are cruising down the interstate at 70-80 mph you likely have to use a fair amount of throttle, the cylinder pressure goes up, the pressure in the crankcase goes up from the blow-by in the cylinder, and more oil/air mix is pushed out the breather tube.

And the oil pump is putting out max flow, and the wrist pin is getting a flood, and all that oil is trying to drip back into the sump, and is being smashed into by the piston and I Suspect that the air in the crankcase is a mist of oil at that point and the crankcase vent hose has just a wadded up scrubby like thing that is supposed to give the oil something to smash into and make droplets and drip back down, but, I never gave it a place to vent into and allow the oil to condense out and see how much is escaping and at what RPMs. That would make a good experiment. Maybe mount a liter cola ,plastic bottle, and vent it up high, and see what accumulates and what RPMS and loads cause it.

Or just pour it back in the crankcase whenever you stop to take a leak.

I'm old enough to remember when cars had "road draft tubes" instead of PCV valves and the associated plumbing. Just a metal pipe that ran from the valve cover down the side of the motor to just below the bottom of the oil pan. When the car was idling you could see the oil mist coming out the end of the tube, and when the car was shut off after being driven for a while oil dripped out of the pipe onto the street.

It wasn't considered unusual to have to add a quart of oil every 500 or 1000 miles. Most folks checked the oil every time they stopped for gas.

The good old days

It's the big piston and low air-cooling tolerances...

They have fixed them... with water cooling and multi-cylinders...

Thank God they missed our Savage... ...

Wow!... neat!...
