Page 2 | Peugeot PCV System Repair Kits

This category includes valve cover diaphragms, oil separator membranes, PCV repair kits, throttle valve repair kits, and actuator diaphragms for Peugeot and related PSA-platform engines. The assortment is especially relevant for 1.0L, 1.2L, 1.6 HDi, 2.0 HDi, and 2.2 HDi-type applications. It is built around component-level repair, not blind replacement of complete valve covers or intake assemblies.

Because many Peugeot engines share architecture and components with Citroen and, in diesel families, with Ford, Fiat, Volvo, Land Rover, and other platforms. That overlap is useful for sourcing, but it does not make parts universal. The correct part still needs to be matched by engine family, OEM reference, diaphragm size, and the installed component design. Shared platform does not mean “close enough.”

Common symptoms include rising oil consumption, oil residue near intake hoses, idle fluctuation during warm-up, slight hesitation under light throttle, oil in the intake path, and separator bypass. Klifex’s page specifically highlights these early signs and notes that many issues are straightforward to find and fix when caught early. In other words, do not wait until a small membrane failure becomes a full diagnostic circus.

Start with the OEM number and engine application, then check the component type: valve cover diaphragm, oil separator membrane, throttle valve diaphragm, or actuator-related repair kit. Peugeot categories often contain visually similar parts for different HDi and THP engines, so photo-matching alone is weak process control. Use the listing data and original part reference before ordering.

A repair kit makes sense when the failed element is the membrane, diaphragm, or separator component and the surrounding housing is still usable. This can reduce cost substantially while restoring proper crankcase ventilation and intake cleanliness. For service teams, it supports a more accurate repair scope. For owners, it means you fix the failed part instead of financing a perfectly healthy plastic assembly.
