Why would that need replacing. Does the new oil separator and additional pieces not match up with the existing guide tube. I am having a shop do the work, and they too were surprised. I am going to have them compare the existing one to the new one before installing it. Any thoughts?
The "old" dipstick tube has a thin crescent shaped chamber inside where the oil separator line connects that tends to plug up. However I've never had a problem and I replaced everything other than the dipstick tube when I saw the $350 price tag! If you want you can modify the original tube by cutting out the crescent or drilling a new hole, I didnt bother.
