what is the purpose of this? i had the harley s/c swap done on my expedition, but the tech left my heated pcv system in place and plugged the hole behind the iac valve where the harley pcv tube would go. i bought an oil separator awhile back, and want to get it installed, but worry about all the excess hoses from the heated system. there was a member of a different ford truck forum who did this swap on his 04 expedition and had the oil separator as well, but i cant get ahold of him.
