Ok I had an issue with the EGR leaking anti freeze
or too read a code on my engine
tried dealer and multiple shops .
So I made one using gasket material and a grey Permatex that is for water pump seals .

Now when I took it off it was stuck cleaned it out with throttle body cleaner and it was fine but I was leaking anti freeze not much a dribble onto the manifold and quickly vaporized.
So what I did was put a small vacuum line plug forced into the hose and shoved it back onto the idle air control valve .

So far no leak but I was thinking of jb weld in valve were the anti freeze circulates

Now the only reason is too keep the valve from freezing I guess but not really needed ?
Has anyone ran into this and if so how to fix it cause been an ongoing issue .
And do I really need the fluid through my valve ?
Unplugged no codes clamp anti freeze no code
Any thoughts
