Hey there, figured that maybe this might be the best place to ask for some advice.

I recently got a whole new engine replacement on my 2024 Kia Forte due to a few grand mistakes on my end and it’s been running great. My only problem is since then, I’ve been smelling some gasoline/diesel odors coming thru my car vents.

Could this be a cause for concern or is that normal after full engine replacements?
