Why Your Factory CCV System Is Holding You Back

The stock Crankcase Ventilation (CCV) system in Duramax engines routes oily blow-by gases back into the intake tract. Over time, these vapors form carbon deposits in the turbocharger, intercooler, and intake valves—leading to performance loss, increased EGTs, and premature wear of high-value components. For truck owners who tow heavy, operate in hot climates, or push for more horsepower, this system becomes a liability.

Frequently asked questions
What does a PCV reroute do?
The stock PCV system allows LOT of oil to get sucked into the intake, which ends up spewing smoke out the exhaust. The PCV Reroute will allow you to retain the function of the PCV system while helping to reduce the amount of oil consumption caused by high lateral G-forces in cornering.
What is the difference between a PCV and a CCV?
PCV stands for positive crankcase ventilation . CCV stands for Crank Case Ventilation Valve , They do the same job suck fumes from the crankcase into the inlet manifold where they are burnt in the cylinders combustion stroke.
Does PCV affect engine performance?
When your PCV valve is malfunctioning, it throws the air to fuel mixture out of balance and can lead to poor performance and rough idle, as well as misfires. In the very short term, these issues should not damage your car, but if you don't fix the issue, you can do lasting damage, so it's best to get it fixed promptly.
Does a PCV system help increase crankcase pressure?
The PCV valve regulates how much vacuum can pull through the crankcase. It's hooked into the intake - when the vacuum is high at idle, the PCV valve stops most of that vacuum. As vacuum drops with an increase in RPM, The PCV valve opens, to allow a higher volume of gasses and pressure to be pulled into the intake.
