GM 12657323 PCV Oil Separator Pipe 2011-2016 GM 6.6L Duramax LML

Replace your leaking or damaged PCV oil return with this OE pipe from DHD. Unfortunately these components are not available separately. We see lots of these lower nipples broke off during engine removal and installation. 

This pipe connects the oil return on the breather assembly on the drivers side valve cover to the base of the front engine cover on the drivers side. If you'd like to return your oil to a different location or converter this drain to a AN connection, See DHD 007-0298 or 007-0299.
