I have a small oil leak from the standard Lycoming IO540 D4A5 in my RV-10. I have about 425 hours on the engine and it probably started about 100 hours ago. I add 1 quart of oil about every 15 hours so not a safety concern but the leak is annoying and gets on all the stuff under the engine. I tightened the oil drain back hoses but it still continues. No evidence from rocker covers. Any thoughts on those with similar issues and were able to find the location? Difficult to find source since the air movement just moves the oil around and on all the stuff on the bottom of the engine. All thought appreciated
