High oil pressure!
in 912 / 914 Technical Questions
8 years ago
Hello everyone! I have an early 80hp 912 with just over 600 hours on it! I was having oil pressure swings at high rpm so I figured I would upgrade to the bullet style pressure bypass. At 5000 rpm it would run between 50 psi to 60 psi and spike close to 70 psi. I installed the new bullet with a new spring and new plug. I did not add the washer! I also run 20w 50 oil in this engine. Today I ran my first test in the air and I will say that the pressure swing is less! Only problem is it raised my oil pressure to a constant 60 to 70 psi! I am under the impression that 70psi is max psi limit? Any thoughts on how to lower my oil pressure? Or is this fine and should not worry about it? My only thought is to possibly change oil viscosity to lower my pressures? One last bit of info is that todays oil temps were about 220 degrees when it was running at 60-70 psi.
Thanks
