Corsa Uneven idle, PCV valve? Common problem

The PCV (positive Crankcase Ventilation) valve is a common problem across various manufacturers that have these ventilation systems in place.
These valves are common to fail internally and it can be very easy to just replace it and be on your way.
But if you want to know why they fail, stick around and watch the video.

Hope this helps and gives you a better understanding of what goes wrong.
Let me know if you guys would like a video of me going more in depth about these valves

See you in the next one!

That's a purge valve for the Evaporative emissions cannister.

The PCV valve is built into the rocker cover & is also a common failure on these engines. I believe they make a squealing noise when they fail.

Great video, keep it going your time will come 👍🏼. Can I ask you how did you intially diagnose the idle to a bad pcv assuming you didn't just cut Open the part and hoped ?🤣😁

Hie, i have a corsalite which after you rev it stalls or switch off even when driving as soon as you want to change gear it switches off the engine, on the corners if you stops it doesnt idle and stops again . I have changed twice the idle and throttle sensors still no changes. I changed the map sensor too but still have the same problem. The mechanic is also confuses pliz help me diagnost this problem ..

Nice job. Where are you in south Wales? Please😁❤

Incorrect. Not PCV valve, it’s in the rocker cover.

do they make a clicking sound when theyre bad? the idle on mine isnt majorly erratic but when it clicks the idle fluctuates a little, barely noticable. sounds a bit like a slight misfire.

Will the pcv valve being perforated throw a fault code?
