6BT Dual Valve Cover Breather For 89 -98 Cummins 5.9L Diesel
We have prepared a full kit that includes Genuine Case IH Parts.
Includes: Dual Valve Cover Breather for the 89-98 5.9L 12 Valve & 4BT 3.9L Cummins Diesels.
This kit allows you to attach a hose to the valve cover to relieve crankcase pressure and reduce oil loss due to blow-by.
Great for high mileage engines with lots of blow-by, this cover vents from the highest point on the engine to reduce oil loss.
Kit Includes:
- 1 x Dual Valve Cover
- 1 x Breather
- 1 x Seal
- 3 x Breather mount bolts
- 2 x Valve Cover Gaskets
- 2 x Isolators
- 2 x Valve Cover Bolts
Works well with our Billet tappet cover – eliminates messy oil down side of truck due to standard blow by hose exiting from side tappet cover breather
