1989 Jeep Wrangler Laredo With Bad Motor on 2040-cars

1989 Jeep Wrangler Laredo.  (YJ Series )  4.2 L six cylinder engine.  Our mechanic said that there is problems with the Number one cylinder  which has a problem with either the cam lobes on the camshaft rounded out or maybe something happened with the lifters.  The Number 3 Cylinder is not holding compression.  In short the engine will have to go through major repairs or replaced.  It still runs, the mechanic disconnected the two bad cylinders. It runs rough but it is drivable.

The Jeep has a hard top

Here is what we did to the jeep.

The floor on the driver side had rusted out so we purchased a new floor pan and tack welded it into place and used an auto motive bonding agent to seal the floor pan.

There were also some rust holes in the side wall on the driver side. We patched these holes with pop riveted steel plates and sealed these with an auto motive bonding agent.

We used Line X truck bed coating on the floors and side walls on the interior of the jeep after cleaning some surface rust in parts of the floor.  We reinstalled the carpeting.

We replaced the seats with Hunsuker seats. The old seats were broken.  The Hunsuker seats were black but faded to brown with the top being down during the summers . There is a tear in the driver side seat.    

I installed a latch system for the hardtop to connect it to the front window.

It has a new Kenwood stereo with a USB port to plug in an IPOD.

The body was a silver color. We removed the plastic wheel flairs and ground off the rust and coated the inside of the wheel wells with a rust encapsulater. We had the Jeep repainted a forest green color and re-installed the plastic fender flairs with new fasteners.  This was all done six years ago and rust is starting to show up again.  

I replaced the latch mechanism on the tail gate with a brand new latch system. I also replaced a latch mechanism in the passenger door.

The engine was a re-manufactured motor from Jasper Engineering. It was four years old. (That may be in its favor since the motor needs major repairs as detailed above.

The Starter is three years old.

The water pump is three years old.

Some of the steel brake lines were replaced two years ago. 

The brake master cylinder was replaced last year.

I installed a new radiator,  hoses and thermostat last year.

I installed a new cooling clutch fan last year to cool the radiator.

A New carburetor was installed three years ago.

A complete new exhaust system was installed six years ago.  There is no catalytic converter.

When the jeep would not start during the cold snap,  We had it towed to our mechanic. In order to get it started he put in a new battery, Distributor cap, Rotor, Spark Plugs and Spark Plug wires. He was then able to get it started and that is when he discovered the problems with the 1 and 3 cylinders.

The transfer case will shift into low gear and high gear but there is a yoke mechanism on the front axle that engages the hubs into 4 wheel drive.  This is not working.  There is a pressure switch on top of the transfer case that may have went out.
