As most of you know, I just picked up a 1986 Cherokee.

I'm looking for advice or help with what should be looked at and/or taken care of before any serious off-roading or maybe even driving for that matter.

What I have: 1986 Jeep Cherokee Pioneer with 200,650 total miles.
5 speed manual transmission (either the Aisin AX5 or the Borg Worner T5.) And a rebuilt GM V6 2.8L with 30K on it.

The 4X4 had NEVER been used until I used it last Saturday (2/16/2008). I didn't really "use it" I just made sure it all worked. And it's great!
Should I be concerned about the lubricants of the 4X4 system? I was the first and only person to use it in 22 years!

The Jeep sat for one year without being started and it fired up on the second try for me with some help from a fresh battery.

When I bought the Jeep I was told it needed clutch and carburetor work.

I filled up the (bone dry) clutch cylinder with DOT3 brake fluid as specified, pumped the pedal in and out a few times and just like magic, I had a working clutch! About 1 out 10 times the clutch won't engage when I push the pedal in. I'm thinking if I just bleed the whole clutch line this will fix the problem. I wasn't able to find the bleeder where my Haynes manual said it would be. I'll search more tomorrow though. I just gave it a quick look.

As far as the carburetor goes... It seems alright to me. I don't know much about carburetors though. I opened it up and cleaned out the handful size pile of dead flys, beatles and dirt that was in it. I took out the air filter and smacked it a few times to un-dust it. It was basically brandnew.

Once I put the carburetor lid back on I turned the Jeep on and it seems like it sounds and revs a slot smoother without the insects and dirt in the carb. Haha...

The engine idles rough for about 5 minutes after starting in our current 20-30 degree weather. For the first 1-2 minutes I have to keep my foot on the accelerator a little otherwise it will stall. Once it warms up though, the idle is smooth.

The only modifications done to this Jeep (besides the rebuilt engine) is that it has a massive new radiator and a 6 blade cooling fan rather than the stock 4 blade. It seems to run consistantly at 200 degrees but I haven't taken it on the road for more than 3 continues miles yet. However I have been burning off the old fuel while adding new fuel to it along with STP "Complete Fuel System Cleaner" so its had lots of idling time and short drives back and forth on my 1/8th mile driveway.

There appears to be a very miniscule antifreeze leak that seems to originate from the lower radiator hose where it goes into the engine. Could this be a water pump leak?

So now you know my vehicle almost as well as I do. Like I said, I just got it.

If this was your vehicle, what would be the first things you would do for it?

I was planning on buying spark plugs and fresh oil for it today but all execpt for $26 of my pay check went to the DMV and State Farm Insurance. So the plugs and oil will have to hold off until my next pay check.

Should I re-grease all of the 4X4 components? Is that even possible?

Sorry if this post is just rambling on... I'm simply looking for all and any advice/help I can get with what I should do to make sure everything stays in working order.

Thank you, I really appreciate any helpfull feed back I can get!

What do you guys think of these 3 inch lift kits?

http://store.4wheelingplus.com/proddetail.asp?prod=670H

http://www.jcwhitney.com/autoparts/ItemBrowse/c-10101/s-10101/p-100000150007/mediaCode-ZX/appId-10930040/Pr-p_CATENTRY_ID:10000015000710930040

They "recommend" running 31" tires with their 3" lift. That sounds great and all but since my tires are brandnew I'm not planning on buying new ones any time soon. Will my normal 27.7" (215/75/15 tires) be problematic with a 3" lift for some reason?

I don't think there would be an issue... Or would there be?

A rule of thumb for me with any vehicle that I've bought over 75000 miles was to completely flush the radiator, replace coolant hoses, new plugs, wires, cap, rotor (if applicable), new oil, new trans fluid, new diff fluid, regrease all the fittings. If you found tons of stuff in and on the carb I would remove the carburetor and go to town with some carb or brake cleaner and spray everything off with an air gun. my 86 also has a rough idle, but thats because the jeeps have a censor on it that basically tells the jeep it cant run right until it reaches a certain temperature. Sounds to me like you could use an Idler Speed Motor (that specific name) or at least an ISM rebuild kit ($37.00)

Sounds good...

My next pay check will bring:

1. New oil
2. Transmission fluid
3. Differential fluid
4. Transfercase fluid
5. Spark plugs
6. Plug wires
7. Carburetor cleaner

Does anyone suggest a specific type of spark plugs and engine oil to buy?

The guy I bought the Jeep from had drained the radiator when he parked it. I just topped it off with fresh 50/50 mix antifreeze.

ive ALWAYS been a fan of the Purolator PureONE filter and castrol GTX high mile oil, a friend of mine works at an Advance Auto and they have cut several different brands of oil filter in half to find out which one was better, and the PureONE was near the top of the list and its inexpensive. I refuse to use Pennzoil synthetic due to the fact that they use plastic polymers that will create mass amounts of sludge if you don't warm the jeep up COMPLETELY (so on short trips you'd have to warm it up for 20 mins and then go to reduce the sludge build up)

I went with NGK spark plugs, theyre inexpensive, pre-gapped and they have never failed me.

stock size wires from BDW and cap and rotor from BDW. They make good products and havent failed me either. Overall when I did the cap/rotor/wire/plugs swap I paid about 40 dollars or so. my 2 cents

I can not find the bleeder for the clutch line!

I know it's somewhere. I've followed the entire line and the only place I can open up the line is where the bottom half and top half connect. There has to be a bleeder somewhere, right?

Any advice? Anyone know where its hiding?

New issue as of today (2/21)

What causes that horrible squeal when the vehicle first turns on? Is it just an old belt or what?

Thanks -

Tim

yup just the belt , try tightening it up a little bit , it should still deflect a lot , you don't want it to tight just give it a little bit and see if it stops squealing .

plugs ,buy what ever, i buy nkg's for everything because i like the name really . never had a problem with a plug fouling even in my two-stroke with nkg's . but then again i just take care of my two-stroke and ride the piss out of it like your supposed to .

don't buy a fram filter , a wix is the same price and million times better . i am emphasizing the word a million .

castrol oil is good and cheap i run it . there isnt a real difference between normal and high millage , probably just more detergent .


grease all the steering components and the ball joints ESPECIALLY the ball joints they are annoying to change . don't forget the u-joints and it may be worth it to take out the front drive shaft and disassemble the cv joint and grease it if it doesn't have a fitting (usually the needle type not the zerk)

Thanks for reminding me about the CV's and U joints...

My mom had a spark plug litterally BLOW UP in her '97 Ford Escort. It sent ceramic and metal shrapnel into the cylinder and it completely totaled the engine! She had the engine replaced with a newer engine from a Ford Focus ZX3 for $5,000! The spark plug company (don't know the name off hand) recognized their fault and payed for half of the 5K in agreement that my mom wouldn't sue them. So, that's what she did and now her purple 5 speed wagon really cranks out some power! 225HP Ford Escort, haha...

But yeah, personally I've never had an issue with a particular spark plug brand. I try not to buy things made in China though... Can't trust 'em.

Thanks again, I appreciate it. I'll keep you guys updated with everything I do with it.

What do you guys (anyone) think of that 3" lift from Rough Country? $119

My advice regarding lifting would be to start by reading lift information that is in Sticky: XJ Tech writeups from below.
LIFT INSTALLATION WRITEUPS
http://www.off-road.com/jeep/cherokee/xjtech/suspension/liftbasics.html
http://www.rocklizardfabrications.com/home_brew_budget_boost.htm
http://jeephorizons.com/phpbb/viewtopic.php?t=1759

http://www.4x4wire.com/jeep/tech/susp/xj_ome_tflx/
http://fm2cd.com/97XJ/xj_budget_boost.htm

Next is lift with out larger tires going to achieve the look you want?

If not, then the addition of larger tires will cost $ and decrease available HP at tires, which may lead to the slipping of clutch coupled with higher RPM in tough situations (you donít have 4.0), which is what you want. Alco if slipping of clutch is needed it will decrease clutch life, cause excessive heat which can weaken pressure plate springs and possible warp flywheel.

My advice is take your limited budget and make what you have a nice looking reliable daily-driver. Save all receipts for improvements and repairs made, save before pictures, by some chrome cleaner (some 4-out steal wool if needed) apply some labor (low budget) remove dent from door, new paint job, use but donít over abuse what you have. Enjoy all the complements you will receive regarding nice looking XJ. Save some $, look for the 4.0 you want, when found sell your XJ for top $. Buy 4.0 then add lift and larger tires and you will have what you really want.
