I just replaced the gaskets and have substituted the silicone > This is entirely true, most RTV silicone does contain acetic acid as a base which dissapears into the surroundings when cured. Dad works for AT&T and told me there are two grades of RTV Silicone, they used to use the acetic acid based stuff (smells like vinegar) but the fumes it gave off cracked and crazed the surface of plastic splice shields on the fiber and coax lines. The acetic acid stuff will eat at a lot of plastics, ABS included and indeed may start the problem corroding the aluminum, there is a solution the other grade of silicone sealer commonly called electrical grade uses a different base material, though I can't remember what, the caveat is that it costs 4 or 5 times as much. Still change that antifreeze.
