My 04 Disco II with a 4.6 is throwing this code, P0455. It indicates that its an Evaporative Emissions System Leak (large leak).
I have hosed the engine with carb cleaner and there are no indications of any leaks. Does anyone have anything idea as to where this leak may be or what else to check.

Over time crap will build up on it and it won’t fully seal though it’ll sound and appear like it. Lightly scuff it up a bit and it should seal
