I have the same noise in my 97 with an AX-15. At this point I've just accepted it as normal but I'm curious to see if anyone finds a solution. I can also upload a video if anyone wants another video for data.
That’s interesting. I’ve sorta given it over to just assuming it’s lifter tick but to an extreme level. I can definitely hear it get louder when I stick my head down towards the pedals. Mines been coming and going throughout drives, I can’t see any relationship to temperature or pressure when going off the gauges. It has been much quieter than in the past. Been running that rotella for a few months now, haven’t been driving it as much and still waiting for an oil change and I was planning to report back after 500 miles on conventional. Good to know there’s still people watching this thread.I meant to post this here a week ago by forgot, so i lifted my jeep and i had to remove my shifter boot in order to shift into reverse because of the motor mount and body lift so right now its basically an open path to the transmission.
The noise is FOR SURE coming from either the front of the transmission/back of the engine, I can clearly hear it with the shifter boot off and locate it.
I have a pressurized smoke machine at work. I pressurized the exhaust system from the tail pipe with 7 psi and found no smoke. I was 100% confident on this being an exhaust leak. Not sure now.Yeah 10k miles later on my Jeep and its still the same noise but no negative consequences. I hardly even notice it anymore.
Mine sounds nothing like the video in that article. I do have slight lifter tick (which would be more alarming if I didn't with this engine seems to be the running joke) but it isn't that extreme.Could it be a bad lifter? It sounds like the video referenced in this article.
