Water Jacket Plating?
 

I was told Merc plates the water jackets with brass, Possibly a myth, anyone know?

Anyone have experience coating or plating the water jackets of their cast Iron blocks or aluminum heads?

Aluminum intake manifolds have bronze inserts cast into the water crossovers.

Can't do it "after the fact".

The block would have to be acid dipped to prep it for anything to stick to it properly. Then you gotta choose what you are gonna try to stick to it. Of all the choices that would offer corrosion resistance, they all are thermal barriers. This is bad. With a thermal barrier, there is no way for the coolant to actually cool anything...

The plating would have to be a metallic material. While I guess you could copper coat and then follow with zinc, it would cost more than a new block...

Best and least expensive way to "plate" your water jackets is to add a closed cooling system to your motor. Then it will be "plated with coolant" Service it properly and your heads, block and fittings will last for almost ever.

I asked this before, Who makes a nice, sanitary closed system that can cool big power?

Pictures anyone?
