Newbie seeking advice of a master
Hello all I'm new to the thread and new to fooling with cars in general. I only have a very basic if even of engines . I own a 98 ranger XLT with a 2.5 L 4 cylinder in it. Recently it decided to sling a rod so I baught another used engine . Ive purchased a gasket kit to go on the new used engine I purchased but have no idea of what I'm doing to even start the project . Please someone help with info or some link that would provide me with pictures and such for me to be able to follow . Thanks in advance !

With only a basic understanding of an engine, I would not recommend you doing any major engine work.
What about the other used engine, if it's running well, clean it up and install it.
Are you thinking of replacing the head gasket ?
What you're asking is like someone saying, "I'm not very familiar on rebuilding an engine, can someone tell me what to do" ?
Guys go to school and text books have been written on the subject.
It's kind of beyond the scope of a forum to talk you through something like this with out having to type pages of info.
What tools do you have, you will need a torque wrench, one for inch and foot pounds ?
With so little info to go on, it's very hard to tell you where to begin.
You will need a manual for torque specs.
Does you gasket set have new head bolts, torque to yield head bolts will need replacing, assuming the 2.5 uses them.

Welcome to the forum
So you have another 2.5l Lima engine, they were only made from 1998 to 2001 for use in Rangers and Mazda B2500 pickups of those years
"Gasket kit" is not to specific, there are several "kits" for doing specific things to an engine.
i.e. "head gasket kit" would have head gasket, valve guide seals and a few intake gaskets, and exhaust gaskets
Intake gasket kit would just have the intake gaskets and maybe fuel injector O-rings
To start you need to take lots of pictures of where wires and vacuum line go as you disassemble the old engine for removal.
You can have 1 too few pictures but never 1 too many, lol.
You need to remove the hood, and radiator
Then engine wiring harness from engine hook ups then pull it back out of the way.
Disconnect the fuel line, need a special tool for that, semi-circle plastic ring set, do not use the metal scissor type they don't work well
Unbolt exhaust manifold from engine, or unbolt exhaust pipe from manifold
It is best to remove intake manifolds, upper and lower, before pulling engine out, but lower can be left on.
If automatic you will need to unbolt the torque converter from the flex plate via the access plate under bell housing, there are 4 nuts or bolts, around the edge, you need to rotate the engine to remove all 4.
If you have "thrown a rod" then you may not be able to rotate the crank 360degs.
If this is the case then you can pull out the engine with torque converter still attached, BUT..........
It will be MESSY as heck, trans fluid will pour out of torque converter as engine tilts backwards, so have larger pan under bell housing and as soon as torque converter is out enough have a rag ready to stuff into the hole in the back of converter.
Transmission needs to be support in the front, auto or manual, when you are ready to pull the engine.
Engine lift/hoist, you need a flat smooth surface so the hoist can roll
The Lima engine weighs in at 450lbs so not a light engine
You need to get hoists arm as low as possible on the engine when you chain it to hoist.
Because when you lift that 450lbs up the truck will come up with it, the springs on the suspension are holding that weight now so when you lift it the front of the truck will come up.
This can be a problem if hoist can't go up high enough with engine so it can clear the front body of the truck.
You can Chain the suspension, as is sits now, so it can only go up a little bit
Or you can remove front tires and lower the front down, put it on blocks, so you have enough clearance.
With engine chained to hoist lift it up a little, then remove motor mounts, and then starter motor and bellhousing bolts, keep transmission on jack as well, you may have to lower and raise engine and/or trans to get all the bolts out.
Look on local craigslist for motor stands, they are not expensive, used, and people buy them to do what you are doing then resell them.
You can rent engine hoists for the day, not too expensive, so 1 day to remove engine and 2nd day to put other engine in
Once engine is on the engine stand you can change oil pan gasket and install rear main seal(always do this on any engine when rear of engine is accessible)
