Did you ask why they think it is a connecting rod issue? My guess, it isnt a connecting rod issue. However, the good news if it was a connecting rod issue which can have tick as a symptom, is that if it was a connecting rod issue you could expect it to fail along with a CEL rather sooner then later. What's the truth? Everyone, dealer and warranty company and everyone inbetween, surely knows what this is but they want the owner to eat the liability for it = 100% truth you just received. File a claim, watch how fast the change their tune, but that still doesnt solve the issue. This forum is littered with people who have changed their lifters and still have hemi tick after. I imagine if you got them to crack the engine they would pull all of the connecting rods only to see there is no issue, then if they are worth a bent nickle at least try and replace lifters, and then it would be hit or miss if that actually works. Most connected rod ticks happen after a lifter replacement, not just randomly like this, once a rod is seated and cupped right, chances they went out of whack out of the blue like this is rare. However, hemi lifter tick is NOT rare, but rather common. But they would rather throw you a red herring then tell you the truth because they are really sh i tty people in dealerships sometimes. So if they are correct and it is a connecting rod, dont worry failure is immanent. But how in the world can a connecting rod issue come and go like your video? I would love to hear that knee slapping excuse.
Read the threads in my sig, listen to 100's of ram owners that have went through this and even most of them who solved it without a wrench on the motor. Look at the polls.
