Replacing a used engine that ran 70,000 km due to engine issues. While replacing the engine, I also replaced all consumables and parts that could break in the future with genuine parts. Timing chain, oil pump, balance shaft, oil separator, all hose o-rings, head cover gasket, oil pan gasket, spark plugs, crank pulley... The repair cost was roughly around 1,300+. Now it runs well, stops well, is quiet, and in good condition. The car's exterior and interior are also very clean. After repairs, I replaced the interior floor mats, added a few convenience features, swapped to a North American bumper, and replaced the wheels and tires with nearly new ones like those on a new Rubicon. If you buy a Wrangler JL without care, it can really cost you a lot of money. Buying one that has been fully repaired is beneficial.
