Looking to buy...1988 Wrangler... HELP!

Looking to get my first Jeep Im dying to have one. I found this one that looks really nice but im worried about how old it is and need some advise for what too look for. here is the ad....

"1988 Jeep Wrangler 5 speed. 4.2L 6 cylinder carb. 98,1xx miles. current nj inspection sticker. Have the hard top and doors in perfect condition. Installed side mount mirrors for legal driving without doors.

Jeep has 33 inch tires, 2 inch lift, industrial hood mounted off-road jack, aftermarket tire hooks, on board air compressor with auxillary air holding tank, padded roll bar, am/fm/aux head unit (ipod ready), 2 pioneer 6x9 speakers.

She really looks and runs perfect. Perfect for offroading and turns heads wherever you drive it. Gotta get rid of it cause I need college $. Just installed new battery, fuel pump, and front and rear brakes last month."

I'm going to test drive it tomorrow and see how she runs.

With the carborated motor whats different?
Is the 4.2l just as infamous as the 4.0l?

Please any help would be great thanks!

yea the 4.0 is a descendent of the 4.2, so don't worry about it reliability wise. if the original carb is on it you might want to replace it b/c it is regarded as a piece of crap. that's low mileage so that's good.
main thing to look for is rust.
good luck

If the price is right for your area pick that up. Low mileage, looks reasonably taken care of, and the lift, newish tires, and good seats are a plus.

I have a 88 as well and it does fine. It wasn't near as taken care of as this one looks to be and it does good. It has 123,5XX miles and the only major problem is the clutch doesn't like to work in cold weather, but does fine once it warms up. Get it! You will love it!

Looks good what's they asking for it. Next check out the frame and body for rust. Jeep didnt galvanize the tubs until 93 and the frames untill 95. Also the 4.2 is awesome motor except for the stock carbs. I believe it should be bolted to an ax-15 trans which is also very good.

Not sure I run a 4.0 but id say run it and see if it works for you before you drop money on a carb.

I have a 4.2 with a Weber on it and I hate the Weber. Get a Motorcraft 2100. Once its tuned in you will never have to mess with it again. Plus you can pick up a used MC 2100 for cheap and re build it.

The 4.2 is a great engine. I have had 2 vehicles with it, my YJ and my 75 Scout II. The 4.2 on the Scout was missing parts and still ran like a champ!

If it has the Puegot tranny walk away. The early models have a lot of rust issues in states that use salt (like mine) In one winter I developed 3 rust holes.

I love mine, but with all old Jeeps expect problems. How hard did the PO wheel it?

Main thing to look for is rust. Look at the frame rails near the back bumper where the shackles mount to the frame.

88 should have the peugot ba-10/5 trans unless someone's swapped it out. From what I've read, the aisin ax-15 as only phased in mid way through the 1989 model year run. My 88 has the peugot transmission and it drives and shifts just fine. If it ever starts to act up, I'll pick up a used ax-15 and get it ready to go in, but so far the peugot hasn't given trouble.

SO i checked her out yesterday. I really liked it felt really solid. The guy told me he rebuild the Weber carb but i felt like it wasnt running exactly right. When i popped the hood there were three hoses that weren't hooked up. One has a little air filter on it and the other two were electrical taped and zip tied shut. After asking what they were he said he didnt know. Also there was that liquid gasket it looked like on the head, i think.
After a test drive i fell in love. but im really skeptical about those hoses and gasket. What do all the hoses go to they were all on the left side of the engine if you were standing in front of the jeep. Also how much with labor and everything would the head gasket be?
Im going to have someone look at it on sunday and hopfully, if everything is minor, pick it up on Monday!! Im stoked

4.2's are known to have about 5 miles of vaccum lines connected to something, most of it is for emissions, i run a 4.0 so i don't know specifically what there for, hopefully someone else will chime in.

When I did the Nutter Bypass the wiring took 20min and yanking out all the extra vacum lines took 3hrs.

sounds like vacuum lines to me, one with the filter sounds like a rigged up pcv valve...its not unusual to run across vehicles from this era with LOADS of vacuum lines for some emissions reason. Looks like a nice ride

Someone used rtv to seal the valve cover, not the cylinder head. Using rtv instead of a valve cover gasket is not a big deal so long as it seals.

Those webers don't have the best of reputation for being setup well for 4.2's. They're really designed for small 4cyl engines and I suspect the ones sold for 4.2's aren't ideally calibrated out of the box.

Would this jeep be good as a daily driver?

Have you ever daily driven a vehicle with a carb before? I would have no problem daily driving that thing however I might give the carb some attention or swap it out for something else.

These 4.2's had about 80 miles of vacuum hoses. If you do an aftermarket carb that doesn't have provisions for all that vacuum junk, about 95% of it can be removed. But you have to know what you're doing, you don't want to just start unplugging stuff. Without seeing what was done I can't say what the affects of those zip tied hoses might be.

No Ive never driven anything besides a quad with a carb haha. what is the difference in cars with carbs? will I have trouble starting in the winter? Is there a choke or is it kinda different in a car?

With regards to swapping the carb, putting in the MC 2100 is what was recommended and what I would most likely do. with this carb will I have all the vacuum hoses or will I have to pull most of them out. Also I will have someone doing the major work for me I will be DD it and want it as reliable as possible.

I'm double thinking this so much due to the age of the vehicle... I want a jeep so bad I drove it and love it. I just want it to last...

Then you might be in for a little surprise. I have an old 70's plymouth muscle car I daily drive to work spring-fall so I know all about daily driving a carb. It's not exactly like driving a quad. A carb on a car takes a while longer to warm-up than one on a quad and they are more tempermental. I'm not a fan of automatic chokes so I convert mine to manual choke whenever possible because IMO it improves driveability. Biggest thing you will note when driving a carb is you have to go easy on the throttle until the engine warms up a bit. If you know what to expect, it's not a big deal. Just have to keep in mind it's not key on and stab the throttle like EFI is.

When the timing chain starts to get loose. To tell how loose the chain is, you pop off your distributor cap and put a socket on the end of the crank shaft. You rotate the crank back and forth with a breaker bar and see how much play you have before the distributor rotor starts to turn.
