..The 2.3L you have is a relatively indestructible, low maintenance motor. People just are scared to see a 4 cylinder motor with 8 plugs and 2 coil packs..
..I've put about 100,000 miles in the last 4 years on mine (currently 250,000) which includes daily work hauling tools/materials duty and beating on it off road pretty regular. Major problems in that time was 1 timing belt (normal Life about 60,000 miles) and 2 coil packs cause I busted one off somewhere down the road..
.. I am about due for a clutch, plugs and wires as mine were new about 4 years ago..
..I've literally had fluids venting out of several tubes over the course that I've owned it (all while off roading) and other than swapping the fluids, no problems yet...
..I probably have 4 oil changes in the last 4 years too..Honestly, I still don't know of a more reliable, low maintenance vehicle and motor that can take such abuse.
