Crankcase Ventilation for Fishing Vessel Engine Retrofit: John Deere 6068 TFM76

The Challenge

The owner of a Pacific Northwest fishing vessel was in need of a crankcase ventilation system for his John Deere 6068 TFM76 engine. The current system was not effectively capturing the crankcase blow by oil mist. This was an issue as it created a hazard in the engine room.

The Solution

Solberg offered its ACV Series Advanced Crankcase Ventilation System as a solution to both regulate engine crankcase pressure and remove harmful oil mist emissions that could damage the turbo or bypass their existing unit and vent into the engine room. Solberg also replaced the original engine intake air filter to complete the crankcase ventilation system upgrade.


With the ACV retrofit, the owner was able to capture the crankcase blow by oil mist. The drain line was routed back to the engine sump, below the low oil level, promoting proper draining. This allows for the reclaiming of what otherwise would be lost oil. The engine room was made much safer as the oil mist is no longer accumulating on the floors and equipment.

The Product

The ACV is designed to protect your engine’s turbo, coolers, and inlet air filters as well as help ensure environmental compliance while keeping engine rooms clean, safe & free of oil mist. The series comes standard with industry leading automated vacuum control technology to regulate crankcase pressure and prevent seal leakage. The replaceable
filter element contains a proprietary media pack offering exceptional efficiency levels with an extremely long life, allowing operators up to one year before an element change is required.
