I have yet to delve into the W-1 leakage issue , mostly just because I am scared of the toxic reaction I know I will have , so as an interum test I fiddled with the manifold heat some more;
OK , so this is interesting ..........
I changed the 3/8" steel line for 1/2" copper . Thought the 1/2" would supply a larger quantity of hot gas .
But no! ....... The copper seems to be such a great conductor that the air from the engine fan is cooling it enough for the hot box effect to be less, yep , truck runs a little worse now.
Gonna find something to wrap the copper with next
Then if that doesn't work , water heat , then bite the bullet and go for the W-1 fix .
Updates as they happen
