LLY LBZ LMM CCV PCV Reroute/Delete Kit FAQs
Q: What is CCV delete on Duramax?
A: A Closed Crankcase Ventilation (CCV) delete—often called a CCV reroute—on a Duramax diesel engine disconnects the factory system that routes oily crankcase vapors back into the air intake. Instead of feeding hot oil mist into the turbo and intake manifold, the system vents or filters the blow-by gases externally.
Q: Do you need a catch can for CCV delete?
A: You do not strictly need a catch can for a crankcase ventilation (CCV) delete. You can route a simple hose from the valve cover down past the engine bay to vent blow-by gases straight to the atmosphere. However, using a catch can or a properly sized breather filter setup provides major practical benefits.
Q: Is a CCV reroute worth it?
A: A Crankcase Ventilation (CCV) reroute can be worth it for high-mileage or hard-working diesel trucks (like the Ford Powerstroke) to keep oil mist and gunk out of the turbo and intercooler. However, it is not a required performance upgrade, and it can introduce issues with oil smells, winter freezing, or emissions compliance.
Q: What are the downsides of deleting the CCV?
A: Deleting a crankcase ventilation (CCV) system stops oil vapors from cycling back into your engine intake. However, the main downsides include breaking street-legal emissions laws, risking warranty denials, creating noticeable oil smells or drips under the vehicle, and potential crankcase pressure issues if not vented correctly.
Q: What are the benefits of installing an LMM PCV reroute kit?
A: Installing a PCV (Positive Crankcase Ventilation) reroute kit on a 6.6L Duramax LMM engine redirects oily crankcase vapors away from the factory intake tract. This prevents greasy residue and carbon sludge from accumulating in the turbocharger, intercooler, and charge pipes, preserving cooling efficiency and long-term engine reliability.
Q: What does PCV reroute do in Duramax?
A: A Positive Crankcase Ventilation (PCV) reroute on a Duramax diesel engine redirects oily crankcase blow-by vapors away from the turbocharger intake, sending them either to a catch can or venting them underneath the truck instead of letting them gunk up the intercooler and intake system.
