I have be fluctuating my throttle from 2150-2300 in 10-15 minuet intervals. I have an engine analyzer which give me reading on all 6 cylinders. All temps are close in the 1200-1350 range. The engine breather extends from the bottom cowl 1". Maybe this is not enough. Does this really create a suction if too short? The inside of the stacks are black. I also have a pesco wet pump hooked up with an air oil separator. No oil appears to be coming out of the overflow for the separator. I have the oil return line for the vacuum system ported back to the accessory case to the port to the right of the vacuum pump. Thoughts? Yes I have a scavenge pump. Don't know how to check to make sure it is running but I took the hose fitting off the line that comes from the pump to the oil cooler and it was full of oil. Frustrating... JON

Re: Ranger Engine Question
'Hi Jon,
Using that much oil, if your exhaust pipes are not dripping oil, and the
engine is not leaking, it probably is going out the breather pipe.
Excessive pressure in the crankcase caused by compression going past
pistons, and rings will cause oil to exit from the breather.
A check of the cylinder condition would be to let engine sit for day or
two.. Pull the prop in direction of rotation ( be sure mags are off ).. If
this is problem, engine probably will be hydraulic locked, or release a lot
of oil through exhaust valve out the pipe.
Scavenger pump may not be working and engine full of oil. Remove one of the
lower plugs in the scavenger pump and catch the oil.. At most, the amount
should be less than 1 gallon.. A lot more that this quantity, I would pull
the scavenger pump and check to be sure it is working..
I will be very interested in what you find as the problem..

'Years ago I had a similar problem in a radial. This may not be the same at all, but finding the issue drove me nuts. Mostly it turned out to be the stack on top of the engine for the breather. It had a washer type device that would partially close off the breather for inverted flight, stopping from completely closed by a small cotter pin.

Re: Ranger Engine Question
'Jon,
I had a similar situation happen to me last summer. Ferrying a newly acquired PT 19 home (the A/C had not flown much in recent years) we were consuming well over a gallon an hour. There was a lot of oil under the cowl, on the belly etc. We decided to drain all the oil from the system carefully measuring the amount flowing from each drain point. We drained almost two gallons from the engine itself. We found that a garlock seal between the scavenge pump and fuel pump had failed. Placed a spare pump on the engine and things straightened right out.
Hope this helps.

Re: Ranger Engine Question
'A typical problem with engines overhaul by people who are not specialists, may be to assemble the engine with new gaskets....
On the scavenge pump face, if gaskets are not of the right thickness, the oil is by-passing through the face of the pump, so, it doesn't "pump" properly!
And of course tooth play of the scavenge pump have to be checked maybe more accurately, and looking on the working faces to be perfectly smooth, without any notch or scratch!
seems effectively that your are blowing the oil out of the engine...
So, first, run 1900/1950rpm...
When engin is warm, how are the compression setting? 76/80...78/80???
(if engine is cold, figures will be altered by the oil flowing between piston rings)
And a little thing to check (but need removing cylinders): have the piston rings still good orientation 120degres/120degrees/120degrees..etc...and are there no broken rings? (one hydraulic lock one day, may have damage them).
When you come in the morning, several days after your last engine run, do you ever turn the prop by hand (at least 12 turns=6cylinders, and 4 stroke engine), so you will allow oil to drip from the exhaust stacks...
Usually, there should be only oil drips from the one or two "lower" cylinders (close to the firewal)...if you got oil drips from front cylinders (exhaust stack), there is something wrong with the cylinders!

'Rangers have only a cup washer into a small box in order to make the flow slow down at engine outlet! (on top of crankcase nearby the front on right side)!
By the way, are the spark plugs really dark? black? oily?....or looking dry soot as normal?

Jon,
I had a similar situation happen to me last summer. Ferrying a newly acquired PT 19 home (the A/C had not flown much in recent years) we were consuming well over a gallon an hour. There was a lot of oil under the cowl, on the belly etc. We decided to drain all the oil from the system carefully measuring the amount flowing from each drain point. We drained almost two gallons from the engine itself. We found that a garlock seal between the scavenge pump and fuel pump had failed. Placed a spare pump on the engine and things straightened right out.
Hope this helps.
