Dorman 996-1011 oil separator for the 2011-2013 Kenworth T660 and other vehicles replaces the crankcase breather element as a repair kit. Only the separator is replaced, so the lower aluminum housing stays on the engine block.
- Part of the Dorman HD Solutions line
- Designed to filter blow-by gases and reduce contaminants in the crankcase breather system
- Replaces a separator that has clogged, cracked or lost its bearing to age and wear
- Intended to restore proper breather function when the separator is the failed part
Quick facts
