Previous owner didn't adjust the valves right. #4 stayed slightly open and the exhaust manifold for that cylinder plugged up.
So it didn't die of a catastrophic failure.
Cylinders and pistons are worn, it needs bored.
Had an 11m head on the 12mm block (head holes bored bigger) so it had been worked on.
One rod area on the crank got rusty during storage, I'm not sure how much it would take to remove it or how deep it goes.
$100 for the block, rods and crank. Plus shipping.
Not sure how to ship something like that but I'd do it.
