1995 454XL fresh water cooled (full system) I pulled engine in May for rebuild. Newer riser failed ( I think). Have to pull engine again for V-drive replacement. Today I pulled manifolds and risers on new rebuild with less than 5 hrs. Manifold on inboard side center two cylinders had evidence of water. What am I doing wrong?? I used paper gaskets (green ones) and block off plate CRU-98124. I applied thin coat of perfect seal to both sides of gaskets. tourge to 30 psi ( cant tourge inside nuts, just outside bolt heads) ran to operating temp 3 times, then re-tourged. installed block off plate with 'fins' up in riser. Ideas???
