PROBLEM
The existing closed crankcase breather can freeze in ambient temperatures below -18 degrees Celsius (0 degrees Fahrenheit) on certain 236D/242D/246D/262D Skid Steer Loaders, 257D/277D/287D Multi Terrain Loaders, and 259D/279D/289D Compact Track Loaders, with the C3.3B Tier 4 Final engine. If the closed crankcase breather freezes, oil can bypass the turbo oil seal sending oil into the DOC and DPF causing premature failure of DOC and DPF systems, or it may cause the injector valve cover seal to get pushed out and purge oil into the engine compartment or may cause the dipstick to get pushed out and purge oil through dipstick tube.
