Hello escobar. The first thing you should be doing is buy the Ford Transit Connect workshop manual. Next, the cylinder pressure did not go up enough during your wet test to convince me it is a worn ring or cylinder problem. Here is a test to check your valves. Remove the sparkplug and pump air into the cylinder. You will need to have a tight seal around the sparkplug hole, a cone shaped rubber adaptor around the air chuck is what is needed. You will need to make sure the valves are closed so taking off the valve cover might be the best way to make sure. Pump in the air and have someone listen for air coming out the exhaust pipe. If you hear or feel any air coming out, it is a bad exhaust valve.
