What it Oil Catch Tank?

What is Oil Catch Tank?

Blow-by gasses are one of the gasses that influence engine performance as miles are added to the vehicle. Theses gasses are re-circulated through Engine intake or Air cleaner for re-burn in order to prevent polluted air to escape. Although gasses are re-circulated for re-burn, not 100% of the re-circulated blow-by gasses and other particles are burned off. Portion of the gasses condensed to sludge or oil with carbon residues. Theses sludge build-up in intake pipes and intake manifold decrease efficiency of the air-intake and reduce power output. This may increase white smoke from exhaust.

Oil Catch Tank is installed in re-circulating pipe to collect unwanted sludge and carbon rich oil residues from re-entering intake.
Not only for motor sports applications, but also applications for diesel engine vehicles that is high in blow-by gas is recommended.
Moreover, if you find lots of oils in catch tank, it indicates problem in Engine.
This oil catch tank help detect the problems early stage.
