Can Clogged PCV Valves Lead to Oil Loss in Changan Karvaan?

Mechanics in Pakistan often suspect PCV positive crankcase ventilation valve blockage as a reason for oil loss. Is this a valid reason in the Karvaan’s case?

Yes. A clogged PCV valve increases crankcase pressure, pushing oil into the intake manifold, causing oil loss o r burning. It’s a valid concern and should be checked during servicing.
