I just got a pretty good deal on a Ford FE 3 deuce intake. One issue it has is oxidation in the coolant crossover passage. I can remove stuff close to the ports but does anyone know of a way to remove the oxidation further inside the passage?
I toss em in the sugar sand cabinet, leaves them silky smooth, make sure to rinse copiously afterwards
I've been out of touch for a bit..... how did the intake turn out? On the ones we do, a good coat of por 15 will seal it up for good after it's clean.
I took a good look at it and I think I can get to most of it with a brush. Haven't tried yet, it was at a friends house for a little weld repair and remachining. Corrosion at two corners in the coolant passage. Hopefully I can get to it soon, been working alot.
Someone mentioned Oxyclean for cleaning out aluminum fuel tanks. Wonder if that would work to soak manifold in?
antifreeze is alkalinic try a very diluted acid solution ( HCL or muratic acid ) to break the deposits down with a alkaline wash , if you have mag wheel cleaner try that as it has a mild acid solution and its made for aluminum .
I bought some golf clubs once that needed cleaning so I soaked them in Coca Cola overnight. Maybe you could seal it up and fill it with coke? If nothing else pour some of it over a couple ounces of Crown Royal. It cleans out internal oxidation also I hear.
Several years ago, I was told electrical contact cleaner would clean aluminum corrosion on manifolds, but I suppose EPA regulations have taken the "good stuff" out of it by now. Gary
My favorite is milkstone remover for use in dairy milking systems, it is phosphoric acid and soap. Be careful, as acids like to eat aluminum, but a rinse with baking soda will kill the acid and leave you smiling.
What's the mix ratio of baking soda and water to neutralize the phosphoric? I just want to cleanup the exterior of my aluminum intake manifold and I don't have a sand blaster!
