Kevin, Is it a Michigan plane? What is the N number?
The vibration in climb but not in cruise can be cowl flaps. I assume they are open in climb and closed in cruise. I am on my second Skymaster and living with oil leaks is a way of life. Seems only after a few oil free flights after tighten bolts etc, than the leaks start again. I agree with Mark, put 8 quarts of oil in engines and they spit two out quickly. I general keep 6 to 6.5 quarts in all the time.
Regarding the weldments twice on the engine....Beware!!!!
Regards
Jerry
