Crown engine smoke and power loss

Hey, got a weird one with my 2018 Toyota Crown gasoline engine. Check engine light's on, power's way down, and it's puffing out smoke when I try to accelerate. It's got 110709 km on the clock. Could this be a defective crankcase ventilation valve? Anyone seen this before?

Sounds familiar! I had similar symptoms – check engine light, rough idle, and smoke – with my old 2012 Audi A4. Turned out to be the PCV valve. Did you check the valve itself? Is it clogged or sticking?

Sticking PCV valve, huh? Where exactly is that located? Is it something I can check myself, or am I better off taking it to a workshop?

Yes, that's right! It's often located on the valve cover. Given the symptoms, it's likely a defective crankcase ventilation. I would suggest taking it to a workshop.

Thanks for the insight! Ended up being exactly that – the crankcase ventilation valve was busted. Cost me 360€ to get it sorted, but now it runs like new again!
