Wow talk about bad advice
5.2 are good motors especially the older you go. The later 5.2 had issues with with the intake gaskets going bad and "sucking" coolant and oil into the engine. In my personal experience (over 13 years in the automotive recycling business) I have seen only a handful of bad 318's and most of those were from the owners neglect. I have had over 10 318 engine's and no matter how hard I tried I couldn't hurt one. Solid engines

The 4.7 is a mechanical *******, they have tons of issues and seen numerous failures. They like to sludge up, timing issues, connecting rod issues, head gasket issues, they are just a rolling issue. On craigslist mn you will find tons of sub $1500 1999+ grand Cherokee's, Durango's with bad 4.7 liter engines. I would put them into the 2.7 liter category and that's why yards are asking $900+ for a running engine.

Ford 5.0 are decent engines but they still had weak bearings and also burned alot of pistons on the #7 cylinder because of a misplaced pcv valve that would hammer oil into that cylinder when they hit around 80,xxx + miles.

5.3 are good motors with a nice track record. Good engines with a solid internals and a strong aftermarket following.

If you want a 318 I personally would go for a early version 1967-1972 or a newer version and convert it over to Carb and have fun.

I disagree. In the hands of a respectable owner, the 4.7 can be great. Just gotta keep up on the maintainance, not let it overheat, and that sort of stuff. That being said, I wouldn't "throw" one into an XJ. For the amount of work required, I'd pick other options. I quoted "throw" because there is no just throwing a different motor into an XJ, especially one with a computer.

everyone has their own opinions.... personally i think the 5.2 is a turd.

ive had a few 4.7ho engines and never had any serious issues.

the 5.2 has been nothing but trouble

I'm just going by what I've seen over my years of what is dependable and what is constantly coming in on the flat bed when I was in the salvage business. No offence ment but when you see newer nice shape Dakotas, durangos, and grands coming in with bunk 4.7 engines that either look like a milkshake inside, sounds like a can of bolts being shaken, or not even start because the chain let loose, you kinda get turned off by that. Also everyone that I've torn apart has the sludging problem just like the 2.7 v6 engine had. I was just going by facts I've seen and no offense was ment.
