Confusing Oil Pressure / Temp issue

[amexbmorgan]

Ok- I know the oil pressure issue is not the gauge. Swapping the gauge confirmed same low readings.

I also was able to get the cold oil pressure adjusted to the top of green, however, it took almost all of the adjustment screw to get there. That is not right, I'm thinking to myself.

Is there anyone out there who is willing to have a call to talk things through with me about my issue.

I know I have an oil pressure issue. However, I can't determine, if it is the pump not producing or there is an internal leak somewhere downstream.

I think I understand how the governor sends oil to the prop (Full Feather governor), but want to clarify what I know before I start taking parts off the engine.

PM me if you have time for a call.

Thanks,

Bryan

There is a spring, you can put washers in the shim/adjust the pressure. Best have someone thats done before with you. Not something you want to screw up….

I just went through this on my annual inspection yesterday. I was running 30 psi in cruise and wanted it around 40.

I purchased the replacement springs though Spruce, looking up the numbers in the IO360 IPC. The new springs were slightly shorter than the old ones, but made of larger guage coil.

My rear engine originally had the pressure adjustment just about all the way in, and changing the spring, which is stiffer, allowed us to adjust the pressure in the midrange.

The front engine adjustment was about 1/2 of the way in--changing the spring made the pressure too high, even at the lowest setting. So we replaced the front spring with the original one and turned it in somewhat to dial that pressure in.

Kbecker - Do you have a part number? I replaced my spring with one listed in the IPC, but didn't notice any difference other than color. New one was blue.

Thanks,

Bryan

PS. My new one was part number: 637083

Kbecker -

Interesting! Thanks!
