Engine Rebuild, Electrolatic Corrosion?
Engine Rebuild, Electrolatic Corrosion?
(OP)
Hi all.
Im currently rebuilding an Engine. I am also slightly detailing it. I am wandering, The Exhaust manifold Nuts and studs had become very rusted and where a real pian to remove. I am wandering Will i get problems with accelerated corrision if i use Stainless Steel Studs and nuts/or stinless studs and copper nuts, When Fixed into a Cast Steel Engine block?
If so, Is there any way of preventing this?
Thanks
Steve

Copper nuts are only used on copper studs, for electrical connections.
Brass nuts, heavy hex pattern, on steel studs, are sort of an old- time traditional solution for moderately high temperatures. Steel nuts with Never-Seez are stronger, cheaper, more durable, and just as easy to remove.
Never use cadmium or zinc plated fasteners in high temperature service. They quickly crack and fall off.
