Just one more thing that seem to be our manufacturing team quite confident that there is no any issue from their assembly process because the birth history of this engine is insist with really green.
Therefore, my proposal is need Conti AMC to allowed us to visit you plant in this Thursday afternoon. Hope this visit could helpful and make our manufacturing team to get more understanding on your process. If every things fine, they will not call you anymore in further once the similar issue pop up again.
Please give me reply.
