100k mile maintance?

[ZBTstang]

My jeep rolled over 94,000 the other day. Not beign up on all the mechanical stuff like I should be, I have a few questions. Whoever had the jeep before me didnt seem to take very good care of it, thats another story, I dont think they did ANYTHING to the jeep, in fact I bought it with 80k and the air filter was NEVER changed....
I have a 4 cycl 2.5 liter 98 TJ. Its at 94k miles, do I have to change any belts, timing belts, plugs, anything like that? (I know certain things SHOULD be changed, but is there anything that NEEDS to be changed, or risk having my engine blow)

ignition system..... cap, rotor, wires, plugs... maybe coil.... filters... belts... fluids... check your fuel pressure.. might be time for a fuel pump... remove the valve cover and clean it out.... o2 sensor could be going... or any sensor at that... thermostat... vacuum lines/pcv system.... there are many things that are likely on their way out at 100,000

Well the thing is, new job tomorow, big bucks coming in soon, probably gonna ditch the 4 banger and get another jeep, but it may not come for a little while. Im really not looking to put money into things, unless I HAVE too. Im more looking for things that need to be replaced, like I know in foregin cars if you dont replace the timing belt itll snap and give you a nice yard orniment.

If you plan on getting a new Jeep in the near future (6-12 months) just do the basics (per snitty.. swap ALL belts, change ALL fluids & ALL filters, flush and fill the radiator, then check all your main hoses for detioration and replace as necessary, replace spark plugs rotor and distributor cap, new wires would look nice to a prospective buyer, too.) I wouldn't change out any sensors or fuel pumps if you plan on replacing the entire Jeep unless you know they are bad.

Shifting problem!!!! %@#$*&

Yeah, just like hi_c and snitty said, belts and fluids and ignition stuff. made a world of difference in my yj when it rolled over 100k. i wouldnt worry about the timing chain, your much more likely to break something else like an axle.

 

[hi_c]

Just so you don't freak out from ZBstang's post... Jeeps have a timing chain, not a belt and is very unlikely to break. I have over 165,000 miles on my Jeep with no motor problems... except maybe a little blow-by. But you shouldn't have that problem... yet.

chains can stretch... and break... but unlikely.... though... my friend's corsica just snapped a timing chain
