Helpful Notes

Replace the CCV filter at the service interval or when restriction increases to keep crankcase pressures in check.
Catch cans and breathers help reduce oil mist ingestion; always route hoses away from heat and moving parts.
Verify year/engine (2013–2018, 6.7L) before ordering; some parts span multiple model years.

Frequently Asked Questions

What does a catch can do on a 6.7L Cummins?

It intercepts oil vapor from crankcase ventilation so less oil reaches the intake, helping maintain cleaner charge air and EGR passages.

When should I replace the CCV filter?

Follow the manufacturer interval or replace sooner if crankcase pressure rises or there’s oil weeping around gaskets/hoses.

Will an oil cap breather trigger a check engine light?

Most cap breathers are simple, non-electronic add-ons. Install as directed and inspect for leaks; no tuning is typically required.

Can these kits be used in cold climates?

Yes, but ensure drains don’t freeze and perform more frequent inspections in sub-freezing temps.

Do these parts fit both 2500 and 3500 models?

Yes—fitment is based on the 6.7L Cummins engine family for 2013–2018 Ram 2500/3500.
