The battle with the block oxidation is over. I assume that the reason that it got so bad was due to the prior owners not changing out the coolant.
If ethylene glycol is not changed out every 2 yrs, it becomes acidic and is basically the facilitator for electron exchange for all the incompatible metals that it comes in contact with (copper with the radiator, copper heat exchanger, and cast iron block and heads; copper and iron love to give up electrons).
All stable now. I also errored on the 06/04/2012 comment about mileage. The car had 46,400 in 2005 and had 46,600 mi when received which also explains the issues that came into play to get it on the road again, 200 mi in 16 years is not going to keep the critical gaskets saturated; have a rear main drip to contend with at some point but thats what cardboard is fore for now.
Storage is coming in fast this year but enjoy whats left of the summer,
