id never buy a used engine without doing a compression test, cheap compression tester for about $20.00. you wont know what condition the bearings are in until you run it. take along the person that will be swapping the engine out for you so he can check it out. im sure he will have a compression tester.

Chiming in on an old thread here...
Ok, as a guy with very little time, and no experience rebuilding an engine (I do have a spare 258 on hand to learn with, but not much spare time), why wouldn't I buy an engine from these guys? $1200 (plus shipping and good warranty) for a 258 long block seems like a pretty good deal to me.

just tried their website and got a message they didn't have a 258 for jeep CJ7 (tried 83 and 85).

Unless you KNOW it to be recently rebuilt, on a vehicle of this age you're almost certainly buying a junk. Buy an engine for rebuild or buy a reman.

If you aren't really concerned with a full stock jeep, I feel like the 4.0 swap is the way to go here (assuming that you want to stay with a I6).

Its a pretty simple swap, I did it with no experience whatsoever. I just followed the manual, watched a lot of youtube, and bent the ears (eyes?) of a lot of jeepforum members.

The only thing that really stumped me was the wiring. I went ahead and bought a new harness from Hesco that was a direct fit for my application. And after actually putting it on, I think I could've used the 4.0 harness and made it work with minimal effort.

You get the added power, fuel economy, and reliability of the 4.0 with fuel injection. Plus, parts are readily available. Not to mention, you can find an engine for a lot cheaper.

Just something to think about.

If you are pretty set on going back with a 258, disregard my comments.

Tony,

Did you notice the 4.2L for 1981-85 at Jeep-Engines.com only has a one year warranty. It bothers me you can't find any information on the parts they use for their rebuilds.

Also, they have a core price of $399 and $179 for shipping. So, the total would be closer to $1900. If you send them your old engine, on your nickel, it would work out to about $1700.

I'd be seriously looking at the V8, if I were you.

Matt

$1700 is serious change to keep a low horsepower low revving but good torque lump under the hood. I am all for maintaining these CJs as God and Jeep intended but the 4.0 I6 is such a superior development of the 258 that it cannot be ignored.

I am looking at acquiring a J20 / Gladiator, which over here only came with the I6, and the top of my list is an engine swap to the 4.0HO to get it going. Buying a second hand engine and having it fitted complete would cost around $2000 here.

Wrong website Matt.

www.rebuilt-jeep-engines.com has a 7/70 warranty, core is $150, shipping varies. They also list all the brands of parts they use to rebuild.

For me, I bought a rebuilt 258 for my son's '84 and total cost was $1500. I rebuilt my last one, but I just did not have the time to do it again. The core was not worth the cost of shipping back so I sold it locally for $200. Making my total a mere $1300 for the simplest swap possible. The cheapest shop rebuild was more then that so I wouldn't hesitate to do it again.
