Talking New jeep where to start (HELP)?

Just got a jeep and found a lot more wrong then I thought.
It's a 1987 YJ with 158,800 miles 4.2 inline 6 with a ba-10 with some kind or lift with springs over axles. Stock axles believe 35 rear 27 front or some thing. O and be gentle! Please

Where should I start with this project? I will have to do a few at a time so my wife with not kill me. It will have to drive on the freeway to get to trails. Wife would like to drive it as well.

1) milk looking oil after drive it home.
2)Oil leaking for all over and onto headers when driving very smokey
3) Lift not looking right some bad wielding one wield looks to be breaking on the frame where the front shackle mounts.
4)Tires are toyo 33's at 13.5 width and rub at full turn
5) Some vibration at higher speed

Drives ok on the road and freeway a little loose. not a lot of power in the motor had to stay in 4th most of the time. Could not get over 62mph

I think it needs a new motor? get a long block (same motor) or do a swap?
Needs a new lift?
New Tires
Thanks for your help

1) milk looking oil after drive it home. Check head gasket.
2)Oil leaking for all over and onto headers when driving very smokey. Might need a new rocker box cover and or gasket, check year and dealer. Most gasket units are after market.
3) If your jeep is leaning it could be bad shocks, mounts, or leaf springs. Also check to see if a track bar is installed.
4) Seems like your tires are too wide.
5)check alignment/balance for your too wide tires.

I will bring it down the the tire shop and have them check over the tires and aliment for it.
Head gasket Will check and see. I pulled one plug and it look normal light brown.
Do you think I need spacers for the wheels?

Thanks
Jason

1: Milky oil is more than likely due to a bad head gasket causing coolant to mix with the oil, this is not a good thing especially if it was being driven prior to your purchase and subsequently you driving it. Basically the coolant more than likely has done damage to the internal bearing surfaces so the engine might be totally shot. A rebuild/swap will be necessary in the very near future.

2: The valve covers on YJ's tend to leak after awhile, could be as simple as a valve cover gasket or as stated above the head gasket.

3: Bad welding is not a good sign especially if it has anything to do with a lift, most lifts do not require welding and are only higher arched springs on a leaf sprung vehicle, I'd be very concerned if your frame is cracked.

4: Unless they are on offset rims the will surely rub and on the tub as well if the lift is not high enough.

5: Tires of those size will certainly cause vibration problems, they can be very difficult to balance if they have been at all. It could also have to do with bent rims, drive shaft angles, worn out suspension and steering parts.

My advice would be to post up a bunch of pics relating to the problem areas of your jeep, that way people can get a look at what your talking about and offer suggestions on how to go about the repairs. Unfortunately your going to probably dump a bunch of money into it if you ever want to make this thing roadworthy again, kinda sounds like you have taken on quite the money pit/project, hope your pockets are deep and you have a bunch of time.

Dont be too overly concerned, each thing you mentioned is easy to repair.... Its a jeep. A little at a time would be the best approach, do a triage meaning problem you should worry about most. I would address the engine first-not a big deal. Worst case drop in a replacement in one day and move on. Ditch those meats, nothing but problems and power robbers. Put on some reasonable tires and really check that frame. Drive it to evaluate where you are at with it and go from there. They are all works in progress. Just my thoughts. Good luck fellow jeeper. You will be wheelin in no time.

I think it will be a money hole but I hope that I can build a nice rig the way I want it. Looking for the silver lining

What size tires should I go with if I put in a new 4.2 6 cyl?
Rims need back spacers?
Thanks for all your help

33 should be ok with right gear, the width adds a tremendous amount of mass for the engine to turn. Those things are heavy. With the right gear you can drive it on road easily if they rub check the seer stops. You could take measurements or run it to rubbing point and eyeball the possibility of spacers?

The lack of power you describe could be too high a gear, not lack of engine power. If all 6 plugs look good and no oil smoke from exhaust, enging is probably ok just minor issues like gaskets. Carb ok? Run rich? Ive had the 6 go 250,000 and still run good. Just my thoughts.

Get the motor running right first. I'm assuming you have 3.55 gears, and yes, with 33's you will not have 5th gear unless going down hill with a tail wind. You can adjust your steering stops or get new wheels with less backspacing to cure the rub. 33" tires should not "cause" your vibration, worn out parts will. Do you have a SYE? Now is the time to check for worn steering components, u-joints and bushings. Before dropping a bunch of money on upgraded fancy parts, make sure your parts that you have are in good working order, if not, upgrade from there.
P.S. Check those welds also and get them fixed. That is not a "bolt in" lift kit if it is SOA.

The leave spring are on top of the axles with u clap and a plate.

Is this the right way to lift or a hack job?

The leaf springs have JRS on them any info on that?

A spring over axel lift is totally legit if done right. Bad welds for the spring perchs are not good sign, but they are easy to fix. Id take it to a local welder and price a re weld. Slip yoke eliminator is a most. I would get the bad welds fixed before that let's go at 62 mph
