Trafic engine smoke reduced power

When you mention 'gunked up,' is that a visual build-up, or is there a specific test I can perform to confirm the malfunction? I want to pinpoint the issue precisely before replacing parts or misdiagnosing it.

Definitely a visual build-up, like thick, oily sludge. Try disconnecting the PCV valve and see if it's blocked. Honestly, with those symptoms, and knowing the age of these engines, I'd just replace it. It's a cheap part and might save you a bigger headache later. If the problem persists after you've cleaned or changed the valve, going to a decent mechanic is a good call.

I'll inspect and likely replace the crankcase ventilation valve. The projected repair cost of 360€ seems reasonable, considering the potential for more extensive damage if I don't fix it. Thanks for the guidance!

Hey, I had similar symptoms on my Trafic! Reduced power, smoke – the whole shebang. Check your PCV valve and the hoses connected to it. Mine were gunked up pretty bad. I'd start there before digging too deep.
