I'm having to replace my intake cause of a bolt breaking off trying to replace the thermostat. Question is I noticed there is a part attached to the head, right in the middle of where the intake goes, that wasn't attached to the intake. It looks like a water port for the heater and has a sensor coming out of it. Do I need to remove this and clean all the gasket(was a royal pain on the intake, ended up taking with me on vaca and having my brother do it with 3m disks and a rotary air tool) or can I just cut this part of the intake gasket out and not touch it? Any advice is greatly appreciated. Thank you.
