ECI-360 oil pressure problem solved

[Earl Findlay]

Another great flight today. I added 1/2 a quart of oil, and then took her flying. Oil pressure 82 - 87 psi once warmed up. Yahoo!!

Blackstone Labs report came back. "Hi Earl. Very impressive results since the last time we received a sample. Even for a 255 hour motor, these numbers are well below what we usually see. Low aluminum, iron, and lead tells us you're running this engine right. Your sample gives us comfort that extending your oil change intervals from 35 hours to 50 hours should be of no concern. Keep doing what you're doing!"

I was ecstatic to receive such a fantastic report.

I continue trying to monitor for any potential problems with OP since making sure the quantity is always correct, but so far unwavering OP has been the only thing noted.

Engine hiccuped a bit today for just a split second; probably water in the fuel (I did not sample any, however) as its been raining some, and my hangar is not water tight. Still, that'll wake you up!

I?ve been running an ECI IO360 for 8 years and have never seen a change in oil pressure more than a pound or so! Always run 7 quarts but I have cold air eduction so that may be different than what you are running. The point is, steady as a rock since new. What you are describing would make me investigate further than on this forum. Just my .02 worth.
