Description
Replace the crankcase breather on your Dodge Ram 5.9 diesel with a Cummins 3957987 Genuine Crankcase Breather Filter. The crank case breather sits on top of the valve cover assembly and allows the crankcase gas to vent. Over time the filter can become clogged leading to excessive crankcase pressure. This can lead to severe blowby, blown seals, and oil leaks along with oil passing through the turbo.
Features:
- Genuine OE Part
- Direct-Fit Replacement

So far so good
Tabitha (Idaho) | February 23rd, 2025
I just had my mechanic do a complete rebuild on my 05 Cummins (engine threw a rod). This was one of the parts he sent me that he needed. I just picked up my truck a few days ago and everything is so far so good :) Only have 100 miles on the new engine but will try to update if anything major happens down the road. Thank you for stocking everything I needed to complete this rebuild!

A small but vital component in the life of the 5.9 L Cummings Engine. This is a good product backed by the great brand.
