LBZ CCV Reroute Options
Three fitment-confirmed choices, depending on whether the reroute is the whole job or part of a larger cleanup.
What the Reroute Does on an LBZ
Factory routing sends crankcase blowby back through the intake tract. On a truck with miles on it, that oil vapor coats the turbo inlet, the charge piping, and the intercooler over time. A reroute sends it outside that path instead, and owners typically find a noticeably cleaner intake side at the next service. On the LBZ the job is straightforward compared to exhaust work. The standalone kit covers a wide 2004.5-2010 Duramax span because the routing is shared across those engine codes, while the CAT/EGR/CCV packages are LBZ specific and address more of the truck at once. If you are already planning EGR or CAT work, the combined kits save you a second round of shipping and labor.
Why LBZ Owners Order From EngineGo
The LBZ has a following because owners keep them a long time, and parts availability matters more on an engine this age. Every listing here names the engine codes and years it covers and lists what hardware arrives. Orders ship from U.S. warehouses, most process the same or next business day excluding Sundays, and free shipping applies within the continental United States. Authorized returns are accepted within 45 calendar days on qualifying items. If your truck already has intake piping changes or a previous reroute, send photos of your current setup and we will check clearance before you order.
Shop LBZ CCV Reroute Kits
If the reroute is all you need, the standalone kit is the direct pick and covers a wide Duramax year span. If your LBZ is due for CAT and EGR work anyway, the combined kits handle everything together. This is a small category, so if you do not see the exact configuration you want, send your year and model and we will tell you what fits.
