Anybody swapped engines in their car before?

I bought the kid a Jeep a few years back.  About 6 months ago, I was told it needed a new engine, and I need to stop driving it before it seized.  I got two other opinions - same thing.

I do almost everything myself.  Estimates are $2400 labor to get this done.  I am not feeling that generous.

I got the service manual, and it doesn't look too hard.  Look like most things with cars - just a whole lotta wrenching.

I've done about everything else but pull an engine.  If I do it, then the car is mine, so I may keep it and do it over Thanksgiving break.  Maybe take Mon-Weds off, and plan 3 days to do it over the 9 days I'd have off.

Anybody done it - is it as straightforward as it seems?

BTW - of course, if I do the engine, the next things are a winch, new coils, lift, big ole honker all terrain tires, transmission cooler, maybe some other stuff.

If I'm having a Jeep, it's gonna get rednecked.

I pulled one and had it bored out and had the pistons and rings replaced then I re installed it in a 72 Ford truck. The problem isn't the motor pull and reinstall, it's all the extra brackets, screws, plastic attachments, associated equipment, and electrical attached to the motor. The older the vehicle, the less crap on it. New motor mounts are a good idea too. You can buy a crate motor and give it a shot, but I fear you are going to take longer than you think. You will have busted knuckles and a sore throat from cursing. If you go this route, you should give us a pic of the small box of extra leftover nuts, bolts, washers, and plastic clips you will have when the job is completed. You won't have a clue where they go.

Get a engine lift, you are going to need it.  Anytime you detach something substantial like transmission mounts, or etc., make dang sure that you have that fully supported.  Take time to build up support if it is needed.  Things happen fast, and you would hate to save $500 and lose a finger in the process.

Watch 100s of videos on youtube.  They walk you through jeep motor replacement.  They will drop hints and crap you always miss. You just have to watch enough of them before you get started.  After the first 10 or 12 just go through the mundanes using your arrow keys, only looking for the tips.

I like this guy.  He drinks a beer while swapping a motor, so you know he knows what he is doing.   He also shows you how to install the motor and not have any left over parts.

Definitely start with a crate motor.   Putting a whole motor together and doing the install is insane. 

Get a friend signed up for the day you are hoisting the motor in.  Someone that is mechanical and patient.  Definitely helps to have 2.  

Take loads and loads and loads of pictures as you remove the old engine.

First but yourself an oem service manual because you will need it. If it is newer than about 1995 you better have an obd reader. Normally easier to pull engine and transmission, but dependent on vehicle. I'm not familiar with Jeep's. Have at least 2 friends, one of which has replaced a motor before. Give yourself 2 days with a crate motor, a week for a rebuild if the heads need no rework. Follow the vendor instructions when starting the new motor and break-in. Use the oil/weight they recommend. Do not use synthetic oil till at least 2000 miles (3rd) oil change. Pics, pics and more pics. Better to have a laptop with WiFi close by. Videos and pics suck on a phone! Get a rewards card from you favorite auto parts store, it will payoff. Label and Ziploc bag all parts as you take them off, store them in order you take them off (good wife or 2nd friend job). If you have the time, replace all mounting bolts with new grade equivalent bolts. Since you have everything off, woulld not be a bad time to replace the sensors. Good luck ....oops forgot, have favorite beverages available for consumption and gift when the swap is complete.... Not before. Lots more to this effort depending on the motor you buy.
