Hello.
2009 RV7A, 250hrs on Mattituck IO360, 250hrs TTSN.
Recently my oil pressure has been running too high, as indicated by my EIS4000 engine monitor.
The norm was 85-90 psi on takeoff, then as oil warmed up it would settle in the upper 70's at cruise.
Now it reads 97-98 on takeoff, even if i let the oil get warm before i take off. and even if i pull back at low MP, it stays 94-95.
I run Aeroshell 15W50 (but, again, this high pressure seems unrelated to oil temp), current oil/filter set has 15 hrs on it.
Before I go through with oil, filter change and transducer replacement, I want to show a picture of the oil pressure relief valve I took last night.
(Please note that I have never touched it so far).
If I put a wrench to the locknut I can easily turn it clockwise (without taking the locking pin out), so easily that I can almost do it by hand. It does not turn counterclockwise (it seems bottomed-out).
Is this normal? Do you have any suggestions?
Thanks.
