Intake manifold is junk. I found some deep pitting inside the water port along an intake runner. I knew that area would have to be thin as deep as the pitting was. I used a 90 degree little poker and poked around from inside the intake runner and it poked right through to the water port. I have another one I can use but it is not a great one. I will eventually pick up another one but for now I will make my extra one work.
