Carbon buildup is a common issue in many car engines over long-term use. The formation of carbon deposits can affect engine performance, fuel efficiency, and emissions. To effectively address this problem, various combination solutions have emerged. This article compares several common solutions to help users choose the most suitable one.
1. Dual Catch Can System
Combination: Two oil catch cans, one for the Positive Crankcase Ventilation (PCV) system and one for the Crankcase Ventilation (CCV) system.
Effect: The dual catch can system comprehensively captures and isolates oil vapors and contaminants from both the PCV and CCV systems, preventing them from entering the intake system.
Advantages:
- Comprehensive capture rate: Up to 90% compared to non-use.
- Carbon deposit reduction rate: Over 50%
Disadvantages:
- High cost.
- Complex installation requiring more space. Requires an additional 20% of space compared to other solutions.
Estimated Budget:

Principle:
The dual catch can system employs two separate oil catch cans—one for the Positive Crankcase Ventilation (PCV) system and one for the Crankcase Ventilation (CCV) system—to comprehensively capture and isolate oil vapors and contaminants. This prevents them from entering the intake system, thus reducing carbon buildup.
Function:
By capturing oil vapors and contaminants from both the PCV and CCV systems, this system effectively prevents them from circulating back into the engine, maintaining cleaner engine internals and reducing the formation of carbon deposits.

- CCV reroute kit: $50 - $150
- One oil catch can: $75 - $150
- Installation cost: $75 - $150
- Total budget: $200 - $450
Principle:
The CCV reroute kit redirects exhaust gases and oil vapors outside the engine, while the oil catch can captures the oil vapors and contaminants, preventing them from re-entering the intake system.
Function:
By rerouting exhaust gases and oil vapors away from the intake system, this combination reduces the amount of oil and contaminants entering the engine, effectively decreasing carbon buildup and promoting cleaner engine operation.
CCV Delete Kit + Internal Catch Can + Oil catch can
Combination: CCV delete kit, internal catch can, and oil catch can.
Effect: By rerouting and capturing oil vapors, this combination significantly reduces oil and contaminants entering the intake system, thus reducing carbon buildup. The oil reservoir collects oil from the catch can, further maintaining system cleanliness.
Advantages:
- Reduction rate of oil vapor emissions: Over 100%.
- Reduction rate of oil entering the intake system: Approximately 100%.
- Maintenance of system cleanliness rate: Up to 98%.
- Engine performance improvement rate: Expected to exceed 3%.
