19-Aug-09 Shop night 4 on this manifold assembly and now we're patching holes in two of the brass tubes. We worked so hard to fabricate and fit them that I'm not going to scrap the whole assembly quite yet. From the looks of things, one hole was caused by a rod strike, and the other had the weld puddle contact it. I spend an evening with the Dremel and some sandpaper cleaning the plate and all around the tubes for a clean fit. Not an easy place to work in, inside the cylinders.
