So yesterday I pulled out my ICV to clean it because I had an idle surge on cold starts. Started the car today and everything seemed to work as expected, but I noticed fuel leaking out of the cold start valve, looks like the plastic is cracked. I'm not sure if there's a specific reason the later m20b25 doesn't have fuel lines hanging over the hot exhaust manifold other than not having a CSV, but it seems safer. Has anyone heard of deleting the CSV and relocating the ICV to make it more like the b25? Just a thought.
325e Cold start valve delete?
