I am flying a 1969 Debonair with a continental I520. We are chasing an oil leak on the number 5 cylinder. We have replaced the seals twice and the pushrod tubes and springs once. The last flight was for 3 hours and we lost 1/4 quart of oil. We have dye in the oil.
Let me know if anyone has any ideas on how to fix my oil leak?
Thank you in advance for the help!
