The 2.3l SOHC Lima engine was nicknamed "the Pinto engine" because it was first used in the US in a 1974 Ford Pinto
(was used in Europe by Ford since 1970)
So that's were the "Pinto" name and reference came from
Also called "the Lima engine" because it was made in Fords Lima, Ohio engine plant
This engine was made in 2.0l, 2.3l and 2.5l versions over its 27 year life in North America, 1974 to 2001
Pretty much all engines had a Block Plate between engine and bellhousing for one reason, to align starter motor with ring gear
But over time if a starter bolt gets loose the nose can shift and wear down the block plates hole and you start to get grinding noise from starter from misalignment
Need a new block plate if that happens but most new ones are long gone in 2021
The "washers" are called "shims" in this application, a way to realign starter and ring gear
People also "shim" the bolt holes in starter, thin crescent shaped metal piece that holds starter over to one side more, to align it
And then there is "the wrong starter"
Some engines have different starters for manual or automatic transmissions
Or different years
Need to compare the old starter with new one
Wrong starter in the Box, is not uncommon
Wrong part number look up
