Hi there, Unregistered! Looking to maximize your MPGs or become a Hypermiler?
Take a look at the ScanGauge II, a product that will help you achieve higher MPGs. It, along with other great Prius accessories, is available through the PriusChat Shop!

1st: This will work, If you would rather collect your blow-by in a jar instead of burning it as the engineers that designed the emissions control devices for your engine designed.
2nd: As others have mentioned, this IS illegal. It is illegal to modify the emissions control equipment on your vehicles unless you are:
A: installing parts that are EPA approved
B: pay for EPA testing to prove that the modification does not increase pollution.
3rd: This will not increase fuel economy. Eliminating plumbing that delivers blow-by to the manifold to be burned was quite common on motorcycles. Lots of bikes from the 70's and 80's eliminated the airbox and switched to individual K&N filters on the carbs. The crankcase vent also got a filter to keep the crankcase from pressurizing. I've done this to two motorcycles and sorry, no 25 % improvement in fuel economy.
I think the author is confusing PCV with EGR. I also see the author advocated washing this crap that collects in the jar down the drain or into the groundwater. NICE
