Those 4.0 straight 6 engines will run forever, so your's seems to be the exception to the norm.
She doesn't have a 4.0L engine.
The engine in her Jeep is the older 4.2L or 258ci engine. The engine either sat too long without being used or the rebuild was bad. I could probably rebuild the motor, just lack the proper tools and more importantly time to do it in my garage.
My 1983 has a 4.0 in line injected 6, 5 speed
Must be a 1993, unless someone did a swap? 1983 would make it a CJ Jeep. The 4.0L common rail Jeep motors didnt exist untill 1988 in the XJ Cherokee and 90 or 91 in the YJ Wrangler. Also anything after 92 would be the 4.0L H.O. motor.
