It showed up on a pallet of 2 engines from a local salvage place. The motors had been sitting outside- I rebuilt the better of the two, and still have the rustier.

They had US Marine stickers on the blocks, non- jet manually- adjusted heads, and the rear adaptor on one. Same cam as the Montero, and clean oil!

One had a 'test' tag on it indicating that it had 20- something hours on it- and the inside looked like it. Timing chains, bearings, cams, etc all looked new. Sadly, with the block damage, I had to change the pistons and rings- but then put 75,000 on the thing, and sold it to a friend who's still driving it.

Frank, they had heat exchangers and purge tanks for the engine water jackets, so I really can't explain the rust. Unless the manifold got seawater and the engine got coolant?
