Aoa, Dear seniors , i have mehran 2003, bought it few months ago, overhauled its engine, after overhauling i have driven it around 3k-4k km, today i get to know about PCV valve and its working ,so checked mine car pcv valve,
its hose pipe is blocked by inserting ball bearing by previous owner
i dont know y he did this
so what should i do now, ?? i have removed the ball bearing, pcv valve is sucking air when i started engine,
Dear seniors plz help me, i am new to such kind of stuff and worried about that i was driving it with blocked pcv hose pipe, might have caused damage to the engine
