Help identifying component on v10 intake

[Syoungs]

Was changing an egr on my dads new to him rv. Its a 99 f53 chassis. (Forgot the brand of coach).

Looked down an happened to notice this odd setup. Doesnt look right, but im not sure what the correct fix is. almost looks like a newer set of heads or intake plenum has been swapped at some point, causing whatever this is to not align right.

Coach runs good. Has a intermittent issue with overheating on grades were working through, and had a engine code for egr, which is what led me to discover this.
Its on the rear of the engine, passenger side. Has a ~3\4" rubber hose headed off to the front of the coach.
Almost seems to be part of the heater system, but that system works great.

Any help on identifying what this is, and whats going on here would be great! Thanks

All V 10s look like that. Normal.

Never noticed on my 3v v10 in a f250. Seems odd to have something open like that!

Thanks for the reply, figured it couodnt have been anything to serious with the ckach running so well!
