First off, I post way too many stupid questions in tech. Haha.

Second, I'm wanting to do any maintenance/cleaning/changing (etc.) that'll make my Jeep run better, or especially run longer, in the long run. She's not in bad shape now, but I could use some logical stuff to do before I do the fun things like lifting and all that.

 

change oil every 3000 miles.

 

Seafoam to clean out old carbon deposits.. fluids flush.. check all electrical wiring... check spark plugs and wire.. distributor... fuel system cleaner... check vacuum lines... mmm forgot what else... but i would start there.... good luck

 

Diff fluid, Trans Fluid (DexIII), Power steering flush, Brake Flush, Tcase fluid (DEXIII), Coolant Flush.

 

i would do the following to give it a complete overhaul:

-degrease the block
-drain ALL FLUIDS (engine, trany, brakes, tcase, power steering, coolant, diffs, washer fluid)
-take off the Throttle body and clean it really good
-take off the oil pan and clean the crap/gunk out of it, inspect motor
-replace rear main seal
-replace oil pan gasket
-replace oil filter adapter O-rings
-take valve cover off clean all of the gunk/crap
-inspect head
-replace valve cover gasket
-replace CCV/PCV valves on valve cover
-replace coolant hoses
-replace any vacuum hose that looks worn
-replace rotor/cap/spark plug wires/spark plugs
-replace air filter
-replace fuel filter
-replace oil filter
-clean fuel rail/injectors
-clean battery(replace battery cables if they are corroded)
-clean grounds
-clean starter connections
-clean Alt connections
-inspect fuses in the fuse bock under the hood
-replace belt
-new fluids(per factory specs)
-bleed for air
-make sure everything is torqued down properly
-fill up with a premium unleaded and run a fuel system cleaner thru and run the tank down.

(i hope that i have not forgotten anything)

enjoy all of the work you have just done and how much better the jeep runs =]
