Manifold Help
I am in the process of completing a total rebuild of my Atomic 4 engine and have used your on line discussions as my guiding light in the rebuild process along with my trusty Moyer rebuild book. Believe me you guys are great, I could never have gotten this far if it wisent for all the articles, thank you all. Uniformity I am almost at the end of the process and I think I might have ruined my manifold, can anyone offer some advice
I have kept the manifold for last, all I had to do was to recondition the inlet and exit ports. The tap required was a half inch pipe thread. The threads came out perfect my problems started when I wanted to clean the dirt and old paint off of the manifold
I remembered hearing about people using muriatic acid deluded to clean the inside of the engine. I placed the manifold in a bucket of muriatic acid used for pool use and deluded the acid by five times, water to acid. The result after fifteen minutes in this solution was a slow bubble action. I removed the manifold out of the acid and placed into a bucket of water to soak and then power washed it clean. It came out clean but it had had a metallic odor and the exhaust ports still had black suit. I wire brushed the outside in preparation for painting. Then I noticed a clear orange looking fluid forming a quarter inch line along the cylinder firing order numbers. I cleaned it off with break cleaner and continued to wire brush.
I Took Sunday off, and when I returned Monday, the clear orange fluid had returned, the remander of manifold looked great except for this strange fluid. The Manifold was completely dry when I finished the first day. I am totally baffled and worried, what happened, I will pressure test this week.
1. Does anyone know what that clear orange fluid is?
2. Was the muriatic acid the wrong thing to use on cast manifold?
3. Did I do long term harm the manifold.
