Pull the zinc on the air cooler (big brass bolt on the aft port side outboard of air filter) as that is one of the first to go and see if the zincs have been maintained. Check fluid levels and the looks of the oil.

David,
That big Zinc is not the one that goes the quickest on my 6LYA-STP. The one on the trans cooler and the oil cooler then one of the ones on the water exchanger. Of the six these three are always the worst at the six month interval. I change all six with fresh, they are cheap enough.
