Need a few more miles

I have a 84 Jeep Cherokee 2.8L 4x4 with 180,000+ miles and the valves are clattering badly. I am thinking of taking that off and have them reworked. Am I making a bad financial decision about not going through the entire engine. Have checked out rebuilts and they are also expensive. My goal is to get another 30,000+miles on the top end rebuild. Opinions are greatly appreciated. I have put a new timing chain on in the last 15,000 miles.
Thanks in advance for any knuckle busting advice.

Drive it till it grenades and then if it's worth it (the body and the rest of the vehicle are in good shape), put a rebuilt engine in it.

Yes, you will do the job twice to do a top end with a very old bottom end. Drive it till it pukes and then do it over .

Change the oil a few times a month to flush it out, and try a little Marvel Mystery Oil to quiet the valves. That will cobble it along for a while until you can afford a new engine.

My vote? I would pitch it after it grenades unless you love it or are attached to it. These are poorly screwed together, crude and dull in my belief.

Your drivetrain is worth more than you truck. I would look at swapping in a 4.0 injected Jeep I-6. After the orginal motor goes south.

Jeep engine

I have to agree with my fellow posters here, turn the radio up. The 2.8 engine had a notoriously weak crankshaft. I'm not sure how but we owned 3 vehicles with this engine, 1 an 86 Cherokee, and we never had a problem with engine internals. Sold all 3 cars at the 130K-140K range.
The Inline 6, 4.0 liter is a great improvement on the V6 and has suprisingly more power.
