How to Recover Oil Vapours from the Airbox

Model: (Various brands) Various
Part: Oil vapor hose

Video tutorial

When changing the air filter of a vehicle, when fitting a sports one, a tube is left over: this is used to recover oil vapours, which are then reintroduced into the air circuit. So what should we do with that tube? We have two options: either leave it open and fit a small filter at the end (which will filter the outgoing air to prevent any smells from returning into the cabin).

The second option is to connect the tube to a small oil vapour recovery tank, which will need to be periodically removed and properly disposed of.
