Thank you to everyone for responding to my problem. One thing it really helped out a lot was the graph that showed. The temp is filters bursting at a lower pressure than the champion which I use now and I was able to actually get a little larger capacity one to fit perfect. And by the way, the STC by Airwolf requires that you run the champion. Filter with the firewall mounted remote filter position. One person in the thread mentioned that he had bought a plane and I don’t know how long he flew it for but the hoses he found out later we’re backwards.. well guess what we did a test to find out where the flow was coming from by removing the filter and just turning over the engine and those lines were reversed still seems the filter is a little weak in that the oil pump only puts out 76 psi cold, but with the lines reversed, the spring loaded relief valve will not work Thanks again Mooney space great info helping out the community.

Geez, @N201MKTurbo nailed that one from long range!

Great follow-up woody!!!

 

Something to know about our oil pumps…

1) they are gear type oil pumps…

2) gear pumps have the ability to supply incredibly high pressure when the outflow gets blocked….

3) pressure, is essentially resistance to flow…. The oil pump supplies the flow…

4) Cold oil is a pretty good source of resistance…

5) Where the OilP gets measured… may not actually be the highest pressure the engine sees….

6) the usual spot the pressure gets regulated… is at the far end of the oil gallery. 
 

7) spin on Oil filters typically don’t see high pressures… or their seals tend to leak or extrude out…
 

One two questions…

Did the plumbing error cause any other issues related to oil flow?

was that reversed hoses… or a hose attached improperly to a high pressure source?

 

PP thinking out loud only, not a mechanic…

Best regards,
