I removed the intake manifold this morning and found this. The pin in the secondary inlet port barrel had worn itself loose and
found its way into the engine. Also both of the machined contour inserts were loose and free to slide around and block the upper
secondary port. They are modified barrels which I got from Pineapple Racing. I thought they looked more robust than the built-up
JBweld contour method. When I build up another engine, I think I will just leave the inserts out and forget about contouring. If
its not there, it cannot fail.

up. I am here to tell you these engines are ROBUST INDEED!!!!!!!!!!!!!
