If you want to hear what the MFG say's, here it is:

Lightning / Harley
PCV VALVE KIT
Does your’ Ford Lightning / Harley use oil, smoke on start-up, leak oil from the intake boot or spray oil all over the throttle body?
If you answered YES to any/all of the above then consider this:
The PCV valve that came as OEM equipment in your Ford Lightning’s supercharged motor is supposed to keep the crank case oil from entering the intake manifold under normal driving conditions during which the intake manifold is running in a normally aspirated vacuum mode with un-pressurized cylinders. In this positive vacuum mode any oil coming through the stock PVC valve would drop back into the passenger’s side cam (valve) cover from gravity.
Stock PCV valve shown here

However under an opening throttle especially in a positive boost mode (pressurizing of the cylinders) the airflow in the PVC system of the supercharged motor is being reversed and instead of pulling the crank case vapors out under vacuum it is instead sucking the intake air through the PCV circuit and PCV valve in a reversed direction. As the engines need for air increases the suction at the mouth of the throttle body becomes such that the tube leading from the drivers side cam cover to the intake boot (the crank case PCV air inlet tube) is placed under a reversed vacuum and literally sucks the oil laden air out of the drivers side cam cover and into the intake boot. The PCV valve should stop this airflow reversal but Ford used a PCV valve in their supercharged motors that never closes at anytime no matter which way the air happens to flow. I am sure the Ford Engineers had their reasoning, could it have been so the supercharged motor passed Federal emission standards?
When the boost becomes positive the airflow through the throttle body and into the plenum above the blower increases causing this reversal of the PCV system airflow. The use of a proper PCV valve or as found in our kit two PCV valves would stop this reverse air flow and probably should have been considered as OEM equipment to be installed at the factory. But since the factory PCV valve doesn’t close to seal off the airflow in either direction (no check valve here to stop the air flow) the reversed airflow comes up through the plastic tube that leads into intake air intake boot and disperses oil all over the throttle body even forming puddles in the boot. The oil draw with the stock Ford PCV system is pretty much constant, increasing as the engines RPMs increase.
After installing our PCV Valve kit, you will find that there will be no oil residue in the air intake boot nor being sprayed all over the throttle body and coating the plenum chamber above the blower. Our PCV valve kit allows the pressure to be released out of the passenger’s side cam cover and will prevent the PVC
circuit flowing air in the reverse direction.

What are the benefits of keeping this
oil out of the intake?

What are the drawbacks of allowing this oil in the intake?

The supercharged 5.4 liter Ford motor has an air to water intercooler that cools the intake charge coming from the blower
and going into the cylinders. In order to efficiently cool this intake charge the air passes through cooling fins that transfers the heat built up in the air from compressing the intake charge to the liquid coolant that circulates through the intercooler. How does this oil misting coming from the PCV system affect the intercoolers fins and in turn affect the cooling capacity of the intercooler once the fins are oil soaked and covered with the fine dirt particles that find their way through the best type of air filtration device not to mention the low restriction type that most high performance enthusiasts use on their vehicles.

You will find that after installing our PCV kit that your oil consumption caused by the above described condition will be non-existent

. Other suppliers market a kit or component (oil seperator) that was originally designed for use on stationary air compressors, either as air dryers or oil / water separators. This method employed to eliminate a simple PVC problem can be expensive, messy and time consuming to maintain, hideous under the hood and difficult to install and how long can these devices work as most are designed to be mounted on compressors that have only a one-way high pressured air flow.
Our kit is easy to install (15 minutes or less) with small screwdriver
Nothing to maintain for 1000s of miles.
Nothing unsightly (looks stock)
