Hi RVators,
I am new to lyco's so I'll ask here for some unbiased opinions.
Coming back from a 3H40 long X-country flight last week my oil pressure jumped from the usual 80PSI in the fast cruise to 90PSI which I understand is the bottom of the yellow arc. (red is 100PSI?). It happened during the descent during the last 30 minutes of the flight and remained there 89 to 91 PSI for 30 minutes.
It has never before reached that high...Cause for concern? Where to start looking.
Some other info: Engine XP-IO-360, 200 HOURS since new, oil consumption +/- 1 quart every 4 hours, 3 month old blow by's 77,78,76,78. Fixed Pitch prop, cruises at 2600 RPM LOP at altitudes ussualy 7,500 to 11,500 ft (our airfield is at 5,500 ft). It is time for a 25 hour engine oil change in 40 minutes time, so the oil is close to being replaced...
Thanks in advance,
Rudi
