The Cummins 3999820 Genuine Crankcase Ventilation (CCV) Filter Gasket replaces a blown-out CCV filter gasket on 2007.5-2024 Dodge Ram and Ram 2500/3500 trucks with the 6.7L Cummins. This gasket should be replaced every time you install a crankcase ventilation filter, so it belongs in the same order as the filter.
Fitment
Listed for the 6.7L Cummins from 2007.5 through 2024 in Dodge Ram and Ram 2500/3500 heavy-duty trucks. A 2007 can have either the 5.9L or the 6.7L, and the 5.9L is not listed for this gasket, so check which engine you have. 2025 and newer trucks are outside this listing. Chassis-cab owners, and anyone unsure, should verify fitment by VIN or call us before ordering.
Why this part
The CCV filter gets replaced, and this gasket is what seals it. The rule is simple: every time a new crankcase ventilation filter goes in, a new gasket goes with it. A fresh filter on top of a blown-out gasket is a job you end up doing twice. Ordering the gasket with the filter means you are not halfway through the job with the old gasket as your only option.
It is a Genuine Cummins part and a direct-fit replacement for the gasket your engine came with, so it goes on the way the original did.
What you get
- One Cummins 3999820 Genuine Crankcase Ventilation (CCV) Filter Gasket
Features:
- Direct-Fit Replacement
- Genuine OE Component
About Cummins
Cummins was founded in 1919 in Columbus, Indiana, and has been building diesel engines for more than a hundred years. The 6.7L inline-six has powered heavy-duty Dodge and Ram trucks since 2007.5, taking over from the 5.9L that ran from 1989. Everything in our Cummins line is a Genuine Cummins OEM part: the factory piece, not an aftermarket copy. Shop Genuine Cummins parts.
Frequently asked questions
Do I need a new gasket every time I change the CCV filter?
Yes. This gasket should be replaced whenever you install a crankcase ventilation filter. Putting a new filter on a blown-out gasket leaves the job half done.
Does this include the CCV filter?
No. This listing is the gasket only. Order the filter separately and install both at the same time.
Will it fit a 2025 or 2026 Ram?
It is listed for 2007.5-2024 6.7L Cummins trucks only. For a 2025 or newer truck, call the shop with your VIN and we will check what your engine takes.
