    Hey Mr. Buccaneer —- I too have found the same thing in my LT37 — serial 33072 — made in Peterboro , Canada — I too found it peculiar???? And as with you — wondered why??? On the opposite cover is residue of the same gallery — making me realize there was no gasket between and flow did occur on the outside of the ‘tube” ??? Flow speed restrictor — along full side of cover ??? to evenly distribute cooling — a piece in the middle would cause a cool and hot side ???
