Renault Master Crankcase Ventilation Issue

Hi, I have a 2014 Renault Master diesel with 50975 km. The check engine light is on, engine power is reduced, and there's smoke when I accelerate. I suspect it's a crankcase ventilation valve problem. Anyone had this?

Hey, I had something similar on my Renault Trafic. Is it leaking oil or idling rough? Could be the PCV valve. I remember a weird smell too. Check that ventilation.

Rough idling sometimes, yeah. Where exactly was the leak on your Trafic?

Can't recall the exact spot, but it was definitely around the valve cover area. To be honest, I just took it to a workshop. Probably best to do the same. Cost me around 360€, I'm afraid.

Thanks for the help! I'll take it to a mechanic then. Seems like the crankcase ventilation is indeed defective.
