This is my very first post on this site, so please excuse me if something is not clear or the structure is bad.
Anyways, I am making a very detailed model of an engine, and I am having trouble with making this little niche or how to call it (highlighted - red color). As you can see in the picture, it's coming out of "top" part and smoothly joining the rounded tube.
Any ideas on how to make that? Your help would be so much appreciated!
Best regards, -T
