Ford Ikon Check Engine Light and Smoke

Sounds like a blocked or leaking crankcase valve. Is it throwing any codes? And have you checked for any obvious air leaks around the engine?

How do I check for air leaks in the engine? I have some mechanical aptitude but need guidance for a thorough check.

Honestly, without the right tools or experience, chasing air leaks can be a pain. If the check engine light is on and you're seeing smoke, it's probably best to just take it to a workshop. They can diagnose it properly and replace that crankcase valve if that's the issue.

I'll take it to a qualified technician for a diagnostic evaluation and repair of the crankcase ventilation issue. The estimated repair cost is 360€.
