CHAMP / LUBER-FINER LUBPC74

CHAMP / LUBER-FINER LUBPC74 is a positive crankcase ventilation valve. It meters crankcase vapor and blow-by flow into the intake system so the engine ventilation system can work correctly.

Application / fitment

PC74 is identified as a PCV valve and cross-references to Standard V173 and FRAM FV178. V173 reference data lists push-in attachment, one hose connector, straight nipple orientation and a 1.5 x 1.1 x 2.9" / 38.10 x 27.94 x 73.66 mm dimensional envelope.

• part type: PCV valve / positive crankcase ventilation valve
• function: crankcase vapor flow control
• working area: valve cover, intake connection or breather hose depending on application
• V173 reference dimensions: 1.5 x 1.1 x 2.9" / 38.10 x 27.94 x 73.66 mm
• attachment method: push-in
• hose connector quantity: 1
• nipple orientation: straight
• selection basis: PC74 / LUBPC74 number, flow direction, hose nipple and seating style
• flow calibration matters; visual similarity alone is not sufficient
• cross references: Standard V173, FRAM FV178, PCV1124, PCV220

Before service, compare the removed valve with the new one for length, seating diameter and hose nipple size. Also inspect the grommet and vacuum hoses; a hard or cracked grommet can cause intake leakage and incorrect PCV operation.
