When you buy a truck powered by a 6.7L Cummins, you are investing in one of the most reliable diesel engines ever built. If you have spent any time poking around your engine bay or removing intake components, you have likely run into a frustrating issue: a thick, oily film coating your turbo compressor, intake tract, and intercooler boots. This isn't a sign of an imminent engine failure, it's actually caused by the stock crank case Ventilation (CCV) system.

The Problem with the Factory CCV Setup

As your engine runs, combustion gases inevitably slip past the piston rings into the crank case (known as blow-by). This gas mixes with oil mist generated by spinning engine components, creating positive crank case pressure. To relieve this pressure, the factory setup sends those oily vapors right back into your turbocharger's fresh air intake.

While this design met the basic requirements for a new truck straight off the production line, it introduces significant long term issues for diesel engines:

• Turbo Impeller Degradation: Continuous exposure to heavy oil mist can coat your turbo compressor wheel, attracting dirt and degrading aerodynamic efficiency.

• Intercooler Boot Failure: Over time, engine oil breaks down the rubber and silicone compounds found in your intercooler boots, leading to unexpected boost leaks and costly replacements.

• Intercooler Heat Transfer Loss: Oil pooling inside the bottom of your intercooler creates an insulating blanket that heavily reduces the efficiency of your air to air cooling system, which results in higher exhaust gas temperatures (EGTs).

The $37.49 Solution

Our team of experts designed the 6.7 Cummins Crank Case Ventilation Relocation Kit to address this exact flaw. Instead of dumping heavy, dirty oil vapors straight into your turbocharger inlet, this clean reroute safely directs the crank case pressure away from your critical intake components.

Easy Installation, Long Term Protection

You don't need a professional shop or thousands of dollars in tools to solve this problem. Our kit comes complete with a custom engineered, heavy duty ventilation hose and premium grade clamping hardware designed to perfectly mate with your 6.7 Cummins engine architecture.

By bypassing the intake track completely, your turbo compressor wheel breathes entirely fresh, clean atmospheric air. Your intercooler stays dry, your boots retain their structural integrity, and your engine bay stays clean. 

For less than forty dollars, it's one of the most effective preventive maintenance upgrades you can do for your 6.7L Cummins.
