Use the search engine on this site . You will find lots of Intel. Well hammered subject. Yes get a filter. Goes on the output line before the oil cooler. Lots of ways to do it. I use a Hamburger adapter from Jegs or Summitt Racing supply width -12an fittings or Metric adapters which ever way to choose to do it. I have set several up. Pros - cleans oil, Cons - cost money like everything else.

A 10 micron filter on the out put side of the engine, hot oil is cleaned before it enters the oil cooler. First it keeps the oil cooler cleaner and thus more efficient. Once the oil is cooled it goes right to the oil tank as almost clean oil. It keeps the oil tank cleaner. Most clearances in an engine are 25 microns or more (I've been told.) A 10 micron filter is taking all contaminates over 10 microns out of the oil, meaning that contaminates 10 and under, will not have an abrasive wear effect on engine parts. That's the theory and seem to work. We have fine oil filters on the B24's PW1830s, I fly for the Collings Foundation. These regularly go to 1,400 to 1,500 hundred out before we pull them for overhaul. That does not happen with original metal screens. Before this screw up I did, my M-14p had 1,600 hours on it before I did a top overhaul. When Barrett inspected the lower end, he found it still almost as tight as new. It was very clean too. I had put a 10 micron filter on it when I installed it on the airplane.
The other gadget that really makes big difference in engine life is a pre-oiler. Its been said a number of times, that 70% of engine ware happens during engine start. Again on the B24's PW1830s, we've installed pre-oilers and religiously pre-oil before engine start. That and the filters make an engine last much longer. I have a pre-oiler on my CJ and until this valve failure, my engine was doing just fine at 1,805 hours of operation.

Anyone tried the Airwolf for the M-14P? Is there room in the cowl of a Yak 50?

Who makes the pre-oiler? I have asked around out here but no one knows of one.

Airwolf Adapter $500+ and the hoses and fittings they send are useless.
Hamburger Adapter is $100 with no hoses .
Both use standard aircraft filters that use internal bypass valves.
I feel a pre oiler on the M-14 is not needed as would be the case on a large Curtis 1820 in a T-28 where the clearances are larger along with the huge HP on the rotating components and where "they" scavenge the engine down to nothing including the valve covers which is not done on the m-14. Also you do some pre-oil/charge (short path to engine) when you hand prop the engine which is not done on the larger radial engines with clutch starters.
This shows filter location on Yak mounted under the oil vent tube connected to the engine mount . This is a Hamburger . You can mount is somewhere else. One is on the YakTW the other is on a Radial Rocket.
