My Lycoming IO-360 Has 500hrs since a top end overhaul. The last 2 weeks I have been getting a lot of leaking in random places. After spending a bunch of cash on gaskets. A prop seal oil return lines ect, it was STILL leaking.I even cleaned my crankcase breather line. When I got home yesterday from my flight from FL I figured what the heck let me compression check my engine... #3 cylinder 10/80! After sweeping up my tears i opened her up and found this! Had 3 holes in my piston and it melted a ring completely ! Man I am so thankful nothing bad happened in flight. I still had all my horsepower,fuel flow, my CHT and EGT's were all normal indicating.i had not even a HINT That something was wrong. (Minus some oil on my engine cowling) That goes to show you the abuse these Lycoming can take and still fly. As for me, I pulled the whole engine and will be doing an overhaul. You can't put a price on safety. i sure hope santa can help me out this Christmas.
