I have a 6 with a Lycoming O-360 A1A. I just performed my first leakdown test at 120 hours on my engine. The engine was a new one. I found three cylinders were at 80/77, 80/78, 80/79. The number 1 cylinder was lower though, at about 80/70. It's got me a little nervous as I can hear the leak at the exhaust valve out the exhaust pipe. I know I'm supposed to run it for another 10 or 20 hours or so and then check it again. Problem is I was supposed to fly down to Sun & Fun in April. I'm having second thoughts now. Anyone have any suggestions or ideas? The Sun & Fun trip is 6 hours each way for me from New York. I feel like pulling the cylinder and checking out the valve. I don't mind flying a few hours near my airport but I think a trip is pushing it. Is 80/70 bad? Should I worry?
