Protect Your Engine: The Ultimate Guide to Oil Catch Cans
On modern direct injection (GDI) engines, oil vapor from the crankcase (a mixture called blow-by) is recirculated directly into your intake. This vapor bakes onto the back of your hot intake valves, forming hard carbon deposits that restrict airflow and rob your engine of power. An oil catch can is an essential component that intercepts this oil before it can cause harm.
Why is a Baffled Catch Can Non-Negotiable?
Not all catch cans are effective. The magic is in the engineering:
| Catch Can Type | Function | Effectiveness |
|---|---|---|
| Non-Baffled (Empty Can) | Acts as a simple expansion chamber. Catches very little oil. | Low. Mostly for looks, offers minimal engine protection. |
| Baffled / Chambered | Internal baffles force the air to change direction, separating the heavier oil and fuel droplets. | High. The only type that effectively protects your engine. All our recommended kits are baffled. |
Choosing Your Solution
Use our "Product type" filter to find the right product for your needs:
- Vehicle Specific Kits: This is the recommended choice for most cars. These are complete, engineered kits from brands like Mishimoto and Forge that include the baffled catch can, model-specific bracket, and pre-cut hoses for a simple, bolt-on installation.
- Universal Catch Tanks: These are just the baffled cans themselves. They are intended for custom projects where a direct-fit kit is not available. Installation will require you to fabricate your own mounting bracket and hoses.
