Fits 2003-2007 Dodge 5.9L Commonrail Cummins
By: Hellmann Performance

Running lots of boost? Oil leaks from the crankcase breather system on your Common Rail Cummins engine? Tired of your engine bay looking plain? Enter the Hellmann Performance Billet Valve Cover – solve all of these problems at once. This valve cover was originally introduced to solve issues stemming from high boost applications and a very restrictive crankcase breather system. The OEM crankcase breather seals are prone to failure, and spread oil all over the engine bay. The Hellmann Performance Valve Cover System uses dual ¾ inch crankcase pressure outlet lines (rear of valve cover) to flow into a custom fabricated oil catch can. The bottom of the catch can is designed to return all oil back into the oil pan by utilizing the factory oil return location. 

The Hellmann Performance Billet Valve Cover System includes the Valve Cover, constructed of aircraft grade T6 billet aluminum, the custom fabricated catch can, crankcase breather lines, hose extension (to tie into factory oil return line), clamps, fittings and all mounting hardware. The Hellmann Performance Billet Valve Cover Systems are designed for 2003-Present Dodge 5.9L / 6.7L Cummins Turbo Diesel engines. 

03-04.5 Trucks Have the "Wavy" valve cover like pictured.
If your 04.5-07 Truck has the straight edge valve cover, select the 05+ option below please.

Includes billet oil fill cap!

Substantially more crankcase ventilation for high horsepower applications.

Please allow 5-7 business days before shipment!
