This is an authentic factory original part — never installed, never used. The oil mist separator (also known as a crankcase ventilation filter) captures oil mist and aerosols from engine blow-by gases before they are recirculated through the engine's intake or vented to atmosphere — protecting the engine from oil contamination buildup and maintaining emissions compliance on CAT industrial and power generation engines.\u003c\/span\u003e\u003c\/p\u003e\u003cp dir=\"ltr\" style=\"line-height:1.38;margin-top:12pt;margin-bottom:12pt;\"\u003e\u003cspan style=\"font-size:11pt;font-family:Arial,sans-serif;color:#000000;background-color:transparent;font-weight:700;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;\"\u003eCondition Details:\u003c\/span\u003e\u003cspan style=\"font-size:11pt;font-family:Arial,sans-serif;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;\"\u003e This is a New Old Stock (NOS) part.
