Hi, I have a 96 cherokee 4.0. I know these motors are noisy any way but I cant seem to figure this one out. Lately I have been hearing a sort of rumbling noise from somewhere in the front of the engine. I don't know what rod bearing noise sounds like but I hope this is not it. It has 97,000 miles on it and has been taken very good care of all of its life. Noise starts about 10 to 15 seconds after start up and gets quiter when it warms up. Doesn't quite go completely away though. Has good oil pressure and has only started this about 3 or 4 weeks ago and is getting louder. Any thoughts or suggestions would be greatly appreciated.
Thanks,
Ryan
