What is a CCV system?
CCV stands for “Crankcase Ventilation” On all diesels and especially the L5P the CCV is connected to a valve cover to extract the combustion gasses that have entered the crankcase via bypassing the piston rings, and other gasses as the result of oil aeration. The CCV system connects to the factory intake or intake manifold, in the case of diesels – the intake air horn. The factory intake air horn draws a vacuum across the CCV system by way of BERNOULLIS PRINCIPAL to pull crankcase gases out of the engine and reburn them in the motor. The problem is often as a diesel wears out they endup with a lot of blow by and oil injection into the inlet of the turbo. The truck consumes this oil as part of emissions standards and best practices of crank case evacuation.

What is the purpose of this upgrade to the existing L5P CCV system?
The purpose of this upgrade is to improve the reliability of the existing L5P CCV system, which is prone to failure due to plastic cracking over time, and to prevent high-temperature charge air from the turbo from entering the intake air horn through the factory CCV system.

How does the CCV upgrade system work once installed?
The CCV upgrade system, once installed, allows for more efficient removal of oil from the CCV supply line using two integrated differential drop devices in the CCV block. This method, commonly used in marine and high-output diesel applications, is passive and has no moving parts. It helps maintain a clean intake track and prevents hot air and oil from entering the system.

Why is the factory CCV system problematic?
The factory CCV system tends to fail over time, and when it does, it allows boost pressure from the CCV to enter the intake track through the intake air horn. Additionally, it is not serviceable, and replacing it requires removing the entire driver's side valve cover, including injectors and fuel lines, which is time-consuming and costly.

What is the advantage of removing the factory CCV component?
Removing the factory CCV component eliminates a potential failure point and provides a more convenient and safe oil fill location at the front of the motor. It also separates the CCV system from the oil fill port for safety reasons.

Kit came exactly as described, install was easy, for my model I did not need the hose supplied, I just connected existing hose to new spelab fitting and clamped. Looks great and no more oil on the bottom of exhaust tip or in the boost pipes.

Thank you for your comment and look forward to receiving feedback on your installation!

Was hoping this would keep oil out of the intake/boost lines but it doesn’t so I’ll still have to install a Catch Can.

Hello, you can contact the customer service mailbox to replenish catch can

Easy to install

Easy to install once you remove the factory parts. Wish I would have gone with the black one. Personal preference but I'm just not one for shiny parts

Thanks for the review!!!Very much looking forward to your feedback pictures.

Fantastic Product

2022 Duramax 6.6 Chevrolet 2500
What an amazing product! Beautifully machined and perfectly Engineered.
Now the stupid OEM tamper proof bolts that I had to design and make an easy out style tool that fit 1/4” deep well socket were a challenge. But installed product absolutely worth doing!
Make sure you have the removal tool in hand before beginning project.
Fast shipping on FedEx. Quality Manufacturing and I will buy more products from SPELAB.
I ran my ent back to OEM turbo intake port. Because today’s Low Sulfur Fuel has so little lubrisity the oil entering should help more than harm. But I will track oil transfer and may install a catch can.
Thank You SPELAB for a great product!
