The Difference



The En-Valve is completely different from the outdated system that is still in use today. Even though the present PCV system cannot handle the excess blowby that develops after the engine wears, no one has improved this flawed device used for the last 50 years.

 

When blowby is present in the crankcase, a lot of bad things happen...blowby is a mixture of unburned fuel, water, carbon, soot, and acids. Blowby dirties the splashing oil and dirty oil causes engine wear. For every gallon of gas that the engine burns, one gallon of water is produced. Most is expelled via the exhaust, but some enters the crank case with the blowby through leaking piston rings. Water in the oil causes sludge. Acids cause a coating of varnish to coat all internal parts, clogging oil channels and harming metal parts. Unburned fuel causes oil dilution and loss of lubrication. While carbon and soot help turn the oil into liquid sandpaper compounding engine wear.

The En-Valve, through its design, is able to remove much more blowby. It produces a preset vacuum in the crankcase. Blowby does not exist in a vacuum. The oil and engine stay cleaner and engine wear is greatly reduced. Oil changes are prolonged.

 

As the upper right picture shows, there is only one moving part in our device. There is no maintenance, the valve will not clog or wear. It will outlast your vehicle's life. Take it off and put it on your next car.

You can safely change oil at 9K mile intervals, save money as well as precious oil...pay-back is short term if you currently change oil every 3K miles. Every 9K miles you save 2 oil changes or at least $40.00, and the savings goes on. I change oil on my test vehicle, a '72 Ford pickup, every 4 years, if it needs it or not.
