My Wrangler has developed a faint ticking at idle that I can only really hear when I'm parked next to a wall, but it's been getting slightly louder over the past month and now I'm second guessing every drive. I've read enough forum posts to know the Pentastar has a reputation for rocker arm issues, so every little sound has me paranoid. I'm in Khalifa City and I'd rather find someone local who actually knows these engines instead of a general garage that'll just tell me it's normal. I came across a Best guide to Pentastar 3.6L engine repair near Khalifa City while searching around and it explained the symptoms pretty clearly, which made me realise I should probably get it looked at rather than ignore it. But I'd still like to hear from owners who've dealt with this. At what point does ticking become a real problem rather than just character? And does catching it early actually save you money or is the damage already done by the time you can hear it?
