Hello gents.
Just got back from a long weekend up in the Pocono mountains in PA in our 2012 RAM 1500 Hemi with 83k miles on it. Had 61k when I bought it used in July 2016 - loving the truck so far! Truck drove fine all weekend and on the three hour drive home yesterday late afternoon - though I did notice about a 1-2MPG deficit coming home compared to past performance on this truck.
I unloaded our luggage and started it back up to park it and noticed a loud tick from the engine bay, first time I’ve heard it. Sounds like the infamous Hemi Tick I’ve heard so much about on this forum.
I got up and drove my son the three miles back and forth to school this morning and still heard it. Got home and backed into the driveway and noticed the idle getting rough. Had other things to do all day during daylight hours. Had time to get back out and start it up this afternoon. Oil levels are fine, first thing I checked. Tick still loud and apparent especially on the passenger side of the truck.
First thing I noticed is that it would start with remote start but then quit all on its own with a remote start disabled notification. That’s when I first noticed the CEL. I pulled the codes and it’s throwing a P0308 cylinder 8 misfire code. Still have the loud tick as well.
I have a Q-Certified powertrain warranty that came with the vehicle and I contacted the warranty company and arranged a diagnostic with the nearest RAM dealer but they can’t take me until next Wednesday especially since it’s a big holiday week.
Anything I can try myself in the interim? What should I start with? I’m thinking pull the plugs on that cylinder and replace them as a first step.
I need to check manifold bolts as well what with the tick. Could snapped manifold bolts somehow contribute to a P0308 code? Hopefully it’s not a lifter issue as that seems more complex to resolve. Any advice is most appreciated!
