Has anyone had any trouble with IGSO 540 Oil Pressure, I bought a New
Rebuilt Engine by Performance Engines and it came with (7) Seven Washers
under the Pressure Regulator but still cant get but 53 psi after

Fellow Commander Drivers:
Does anyone have a suggestion as to where one should go to have an
outflow valve for the pressurization system rebuilt for a 680F(p)?
Thanks!
Moe

Jerry,
Thanks for the tip, I will contact Gary.
Regarding the oil pressure problem. It is generally accepted that the oil
pumps on the IGSO 540 series are too small. I can$B!G(Bt remember the GPM
(gallons per minute), however, this has been, as I understand it, a long
standing problem. Once the pump has in-adequate volume, no amount of spring
shimming will raise the oil pressure. Some suggestions:
1. Have you checked the accuracy of your oil pressure gage? (Laugh,
but I have heard some real horror stories)
2. Screw an oil pressure gage into the oil galley at the front of the
engine and compare the oil pressure on the two gages. Lycoming has a
maximum differential that is acceptable, again, I can$B!G(Bt remember what it
is, but will look it up for you if necessary.
3. Will the oil pressure stay in the green while in flight?
4. Will the engine maintain a minimum of 35 PSI at hot idle and about
1,500 RPM (minimum for the fuel pump computer to work)?
Regards,
Moe
