Luckily they sell replacement tops so i went ahead and prdered a poly one instead.

The problem is your radiator not the block IMO. If it is all aluminum then it is NOT protected/anodized on the inside of it. That is causing a problem with the base of the block being it is copper. Clean the system very well and then run 50/50 antifreeze and water. WalMart and other places sell 50/50 premixed. That is what I have been using lately.
This is NOT common though. The Aluminum radiator is bad to mix with a copper based block. My guess is the antifreeze mix was not strong enough. :shrug: Good luck. Good post!
