I'm new here to the forum and I would like some engine advice. I have a 1986 Ranger Supercab, 2.3L, auto, 2wd. My pickup is in the shop because it started running rough, basically overnight. I have been told the engine has almost no compression. I am having a hard time finding a used engine or a supplier of replacement engines for my truck.
Does anyone know a good source for these engines? I would appreciate any other advice anyone wants to give me.

The problem with a junkyard engine is it may need rebuilt as well. If the truck is in good shape, then it may be worth a new engine, if not, it may be time for a new truck.
Do all the cylinders have low compression or just 1 or 2?
I had a 2.3 do that and it was a head gasket. Not a hard job, at least it wasn't on mine. It blew between 2 cylinders, have the head checked also, I had toreplace the head also. I used a junk yard head I had checked, ran it for 2 more years.
Seems like the bottom ends on those engines are bullet proof but the heads are ify.
Could also be just a burnt valve.
I would take the top end apart & take a look before replaceing the whole engine.
p.s. just my personal opinion when you start building repairing an old engine from the top down it normally turns out like trying to build a building from the top floor and working to the ground. it doesn't! save yourself the later head ache and either rebuild the motor you have from the bottom up or buy a new engine. if it's the original enigne from 86 it's most likely due for an overhaul.
but that's jsut my opinion good luck !

I'd be checking the engine myself. Most don't go from running well to falling on the floor overnight unless they are overheated or abused such as running w/o oil, or revved to the moon. Do you TRUST this garage? Have you had prior dealings or a good recommendation on them? Sometimes they need to boost their sales in a given week to make payroll or the rent, and will 'suggest' things that may not be actually totally necessary.
A loose plug or plug wire alone could make the engine run like doo. Or a fuel injector on the fritz or pressure regulator going goosey. Lots to check before condemning an engine...
Just my two cents.

good point tomw! a loose wire or something simple could very well be the cause of the problems. And a rule i try to live by (nevr trust a mechanic you don't know and keep a close eye on the ones you do). Mechanics can be worse than mexican police, they're only out to make money.
A follow up question to this post:
I have found an engine that supposedly runs well, but it is currently mated to a 5 speed manual transmission. Can this engine be put in my Ranger with my automatic transmission? If it can be done, is there a lot of extra labor involved with this kind of swap?
I really would like to go over the whole truck thoroughly myself checking for loose wires and such, but I just haven't found the time yet.
Actually, you would find that the truck would have alot more power, if you swapped in the manual tranny as well. The lima 4 cylinder automatic combonation is a slug.
