we did the water pressure test last night, found the source of the water. it seems that the #6 bore has a crack in it. the water/oil sludge residue in the front must has been driven there by windage from the front of the windage tray. so it looks like its sleeve time for #6. the block had been 1/2 filled to a point nearly 1 1/4" above the crack so we were surprised water could creep down there. now i'm wondering if this had been done to fix this problem in the first place.
