engine breathers

The  1UZFE EGR Delete Kit  is available for sale here.
The purpose of the breather system is to prevent blow by gas (containing hydrocarbons) leaking into the atmosphere.
Hydrocarbons are a major contributor to smog, and long term exposure is known to cause asthma, liver disease, lung disease, and cancer.
Despite the environmental and health impacts, depending on where you live, you can be fined or defected.

Just because you can't see or feel anything coming out, doesn't mean that nothing is coming out
