If any of you folks have an extended working knowledge of the Jeep 4.0 I6 motor, especially the TJ(97-2006) could you please PM me. It is regarding a noise that I’ve had 3 mechanics to address however cannot pinpoint the cause of this particular motor noise issue. I’ve thrown several suspected parts at it, near 1k yo date.
I’ll give responders my cell phone number so we can discuss the issue and not one finger peck, which I’m not very good at.
Again please just PM.
Thanks in advance.
