What Is an Oil Catch Can?

An oil catch can diesel is a reservoir installed in the PCV/CCV system to trap oil mist, vapors, and moisture from blow-by gases. 

For engines like the Duramax, Powerstroke, Hemi, BMW, or the Cummins oil catch can prevents re-entry into the intake, reducing carbon buildup. 

Our oil catch can kits, including 5.9 Cummins catch cans and 6.0 Powerstroke catch cans, ensure clean operation without modifying emissions.

Why Every Performance Engine Benefits from an Oil Catch Can

Installing a 6.7 Cummins or a 7.3 Powerstroke catch can cuts soot accumulation, boosts combustion efficiency, and extends turbo life.

For heavy-duty use, like in a 12V Cummins catch can setup, it saves $300–$600 yearly on maintenance.

Benefits include 20-30% better performance, lower fuel costs, and enhanced durability—ideal for 3.0 Duramax catch cans or Hemi oil catch cans.

How an Oil Catch Can Works: The Science Behind It

Blow-by gases escape pistons, carrying oil vapors. Our dual-chamber diesel oil catch cans use baffles to separate contaminants, venting clean air. 

For the best oil catch can for 6.4/5.7 Hemi, or other engines, this prevents intake sludge, maintaining throttle response. Rigorously tested, our designs excel in high-heat diesel environments.

Types of Oil Catch Cans: Choosing the Right Design

Select a single-chamber for basics or a dual-chamber like our 6.7 Cummins CCV delete catch cans for superior filtration. 

Materials include aluminum for durability in Cummins catch can kits.

Universal vs. specific: BMW oil catch cans or N54 oil catch cans fit precisely. Compare the best oil catch can for 5.7 and 6.4 Hemi options for your needs.
