Not necessarily. All plastic rails are white when new installed. However reaction with oil and high temp make both of them orange. Hopefully you have the new one,but I don't know how to identify them. Assembly date is also kind of questionable because multiple assembly plants managing multiple batches of engines don't gives me confidence. So I opted for 2017 B46 engine, and now fingers crossed for my wife's 2014... for sure the TC of concern.
