SID 97-3 is supposed t= o be performed every annual, every 100 hours, and any time the fuel system h= as been opened.

All,

I am experiencing higher than normal oil temps.  It=E2=80=99s not= unusual to see 210=CB=9AF in the climb.  And then the oil temps remain= above 200=CB=9A during cruise.

 

In the last annua= l, there was nothing done to the fuel system. The magnetos were spot on. &nb= sp;We also checked the temp sensor to ensure its accuracy against three diff= erent thermometers and ran it up and down using a deep fryer with water. &nb= sp;We also pulled the Vernatherm out of the bottom of the oil cooler to ensu= re it was working.  I also called Rosta mfg to discuss the vernatherm o= peration.  It cracked open at 150=CB=9A and was full extended by 185=CB= =9A per the manufacturer.

 

In flight, I started pl= aying with the fuel flow to see if I could lower the temps.  What I not= iced was that If I put the fuel flow about 250=CB=9A Rich of Peak I could mo= ve the oil temp down below 180=CB=9A.  I could then hold it using about= 225=CB=9A ROP.  I also cooled the motor by reducing the RPM to 2300.&n= bsp;

 

Anytime I ran the motor below 200=CB=9AROP t= he oil temp would climb again. This is counterintuitive according to the Okl= ahoma guys recommendations on running the EGT temps.

 

As another point of data, I ran the engine LOP and noticed that I could s= tabilize the temp at 184=CB=9A by running about 45-50=CB=9A LOP. <= /o:p>
