L5P PCV Upgrade system – keep your Turbo and intake air system clean!
What is a PCV system ?
PCV stands for “Positive Crankcase Ventilation” On all diesels and especially the L5P the PCV 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 PCV 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 PCV 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 end up 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 this ?
This is an upgrade to the existing L5P PCV system that is failure prone due to cracking of the factory plastic over time. It also stops the high temperature charge air temp from the turbo from being drove through the factory PCV system and into the intake air horn into the turbo inlet.
The PCV upgrade system once installed will allow more oil to be removed from the PCV supply line by usage of 2 differential drop devices that are integrated into the PCV block. This highly effective method, used for years in marine applications and other high output diesel applications is passive (no moving parts) and will keep the intake track of your L5P as clean as possible and avoid hot air combined with oil from entering the system.
Why did we make this?
- The factory PCV tends to fail and break over time. As it is failing it allows the boost pressure from the PCV to be applied through the PCV system and be introduced into the intake track via the intake air horn.The factory PCV system is NOT SERVICEABLE as a part does not exist until now to replace it. To fix a failed PCV system on the L5P the entire drivers side valve cover needs to be removed including the injectors and fuel lines to gain access to it. This is a 6 hour job and an un-necessary expense!
- By removing the factory PCV component you remove the failure prone oil fill location. The factory oil fill location is in a bad spot for anyone using gallon fill jugs. Our kit locates the oil fill connection to the front of the motor with a billet standpipe tall enough to clear engine accessories and provides a great place to fill the motor with engine oil. It also separates the PCV system from the oil fill port for safety purposes.
- This product has the capability to reroute the PCV system to the atmosphere for race purposes only. This removes the possibility of a run away motor if PCV oil ingestion were to occur during high cylinder pressure or high blow by scenarios.
The factory has 4 safety lock screws attaching the factory PCV to the engine. Installation time is 30-45 min.
