LLY Duramax CCV Reroute

The LLY CCV reroute range from EngineGo directs crankcase blowby away from the intake, where it otherwise builds on the turbo inlet and through the charge piping as ring seal wears. The standalone reroute covers 2004.5-2010 Duramax trucks across the LLY, LBZ, and LMM engine codes, and LLY specific packages pair the CCV work with CAT and EGR delete for 2004.5-2005 Silverado and Sierra 2500 and 3500HD.

LLY CCV Reroute Options

Three confirmed fits, depending on how much of the truck you are working through.

CCV Delete Kit Crankcase Vent Reroute, 2004.5-2010 6.6L Duramax LLY LBZ LMM: the standalone reroute, sharing coverage across LLY, LBZ, and LMM trucks.
CAT/EGR/CCV Delete Kit, 2004.5-2005 Silverado/Sierra 2500/3500HD LLY: CCV, CAT, and EGR handled in a single order.
CAT/EGR/CCV Delete Kit with High Flow Intake Elbow, 2004.5-2005 LLY: adds the high flow intake elbow, which pairs well with the EGR work on this engine.

Why LLY Owners Reroute the CCV

The factory system vents blowby back into the intake, and over time that oil vapor builds up on the turbo inlet and through the charge piping. On an LLY with age on it, the volume climbs as ring seal wears. A reroute directs that vapor away from the intake tract instead. The standalone kit covers a broad 2004.5-2010 Duramax range because the routing carries across those engine codes. The two CAT/EGR/CCV packages are LLY specific and cover more ground, which makes sense on this engine since EGR work is common on LLY trucks anyway. The high flow intake elbow version is worth considering if you are addressing intake restriction at the same time.

Why LLY Owners Buy From EngineGo

Finding correct parts for a twenty year old truck is the hard part, and vague listings waste your time. Every item here names the engine codes and year span it supports and states what comes in the box. 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 has aftermarket intake piping, a previous reroute, or other modifications from a prior owner, send photos and your year and model and we will confirm clearance first.

Shop LLY CCV Reroute Kits

For the reroute alone, the standalone kit is the direct answer. If your LLY is due for CAT and EGR attention, the combined packages fold the CCV job in and save a second order. This is a small category by nature, so send your truck details if you need a configuration you do not see here.

Important: Some products in this collection are intended for off-road, race, or non-public-road use where permitted. Confirm federal, state, and local laws before purchase and installation. Customers are responsible for legal compliance.
