Buying the Right Engine

Brothers are not mechanics. They mis-timed an interference engine and turned 16 valves into modern art. We decided it would be easier to swap in a complete long block.

So the question is: how do you make sure its correct? I want this to be plug and play. No wire splicing, etc...

The car in question is a 2017 Fiesta, with a 1.6L n/a and a manual transmission.

The interballz is littered with engines out of automatic cars. The Power Shift auto apparently likes to eat itself alive, so there are piles of cars with dead transmissions. Can we use one in a manual car? I remember back in the day, some engine's crankshaft weren't drilled for pilot bearings. I cant imagine Ford would still (not) do that.

 Bro found a new, never installed engine in Michigan on Ebay. The ad doesn't say what it might fit. Just says check the numbers. So, how do you do that? The ad has the sticker plainly displayed.

Transverse engines usually don't have pilot bearings.  Those mostly existed because with a typical rear drive trans, the input shaft has only one bearing, so the crankshaft supports the other end.  Transverse transmissions generally have the input shaft supported internally by two bearings, because all of the gears are mounted to it.  A pilot bearing may be counterproductive if the engine and trans are slightly off concentric.

Old timey engines probably actually needed to support the input shaft due to loose production tolerances, really.  You'd see bellhousings .010" or more off of concentric, and rarely parallel either.  The input shaft could flop around because it HAD to.

You probably won't find a "plug and play" because the salvage yards love to cut all of the wiring harnesses off at the connectors for scrap value.  It is very rare to get a complete harness.

Just treat it as a long-block assembly and swap everything over.

If they weren't smart enough to roll the previous engine over by hand before starting it. I wouldn't trust them to swap an engine, no matter how plug-and-play it is.

In reply to Pete. (l33t FS) :

So how can we ensure the engine pictured is correct?
