I just did a leakdown with 60 hrs on my cylinders, the cylinders were done by Jurnigan, I did the labor, I found one at 30lbs and another on the same bank at 5lbs, I used only the good stuff including only av gas, both cylinders are leaking out the ex valves, I made sure the pushrods were adjusted (I added ajustable ones when I did the swap) Just wondering if there might be something else to check before removing the 2 cylinders and sending the back? As always thanks again, Mike (I also tried to reseat with a few taps and no luck)
