FITMENT
- 2006–2007 5.9L Dodge Ram Cummins 2500 3500 Turbo Diesel.
- 2007.5–2024 6.7L Ram Cummins 2500 3500 Turbo Diesel.
DESCRIPTION
Product Overview
- Heat-cycling and mechanical stress degrade stock 5.9L and 6.7L Cummins valve covers over time, leading to warpage, stubborn oil leaks, and poor crankcase sealing. Compounding these mechanical issues, the factory crankcase ventilation system continuously pumps aerosolized oil mist back into the fresh-air intake—coating intercooler cores, sludging air passages, and degrading charge-pipe boots.
- Built as an all-in-one overhaul, this Billet Valve Cover & Oil Catch Can System pairs a rigid, CNC-machined aluminum valve cover with an integrated 300mL multi-baffle fluid separator. It eliminates cover flexing and sealing failures at the cylinder head, isolates oil blow-by before it can foul the air-charge tract, and ensures your Cummins receives clean, un-contaminated airflow.
Key Features
- Replace the warp-prone OEM plastic valve cover with a CNC-machined 6061-T6 billet aluminum piece that won’t crack, strip, or leak under heat stress
- Separate blow-by oil and moisture through an integrated internal baffle before vapors even leave the valve cover
- Capture fine airborne oil mist with a secondary 300mL dual-chamber external catch can featuring a built-in dipstick for instant level checks
- Drain the catch can in seconds via the removable bottom reservoir — no tools, no disassembly, no mess
- Upgrade engine bay aesthetics with a polished billet oil fill cap and anodized surface finish that looks as tough as it performs
FAQ
Q: What does this billet valve cover and catch can system actually do?
A: It replaces the aging factory plastic valve cover with a durable CNC-machined aluminum piece while adding an external catch can that separates oil vapor and moisture from crankcase blow-by before they reach your intake system or engine bay.
Q: How does the integrated CCV baffle inside the valve cover work?
A: The internal baffle system forces crankcase vapors to change direction multiple times as they exit the cover. This causes heavier oil droplets and moisture to condense and separate, reducing the amount of contamination carried downstream.
Q: If the valve cover already has a built-in baffle, why add the external catch can?
A: The internal baffle catches large droplets, but high-output Cummins engines — especially deleted or tuned ones — produce fine aerosol mist that slips through. The external dual-chamber catch can acts as a second line of defense, trapping those microscopic particles before they foul your intake or coat your engine bay.
Q: How frequently should I empty the catch can?
A: Check it every 1,000–3,000 miles as a baseline and drain whenever fluid accumulates. Trucks that tow heavy, run high boost, or see extended idle time may fill the can faster and warrant more frequent attention.
Q: Will this system pair with other CCV modifications?
A: Yes. For complete blow-by management, consider combining it with Seguler’s CCV crankcase ventilation filter kit to keep oil vapor completely out of the turbocharger inlet as well.
