The oil system is pulled from the B and I have take the 3025D to the dealer to find out if the issue I am having is covered under warrenty. The block is back from the machine shop and waiting on the crank and rods. Now I need to get the case and oil system parts cleaned so I can start reassembling the engine on the B. Once I hear back from JD on the D i will update you on what was found and if it will be covered or if I need to take care of it.
