Hemi running good now but found it was low on oil , of course I haven't driven it 20 miles since I bought it as it needed a lot of little things fixed,,,Found this round pcv valve was dirty an little sludge an condensation in it as well as condensation under oil cap , which from research is the pcv system causing issues of low oil and quick starts of engine not getting up to temp before shutting off can cause the condensation ,poor design to me as much as I love the hemi, may add a catch can later if needed but installed new pcv valve for now,,still waiting on shift motor to arrive to get 4wd working I hope , as the transfer case is new an so is front drive shaft thanks to previous owner
After no codes for a few days I started it up yesterday an instantly got 3 engine codes on start up although in ran fine, the codes were P0153-O2 Circuit Slow Response(Bank2 ... sensor 1) P0157 Oxygen Sensor Circuit Low Voltage (Bank 2, Sensor 2) P0306 misfire cylinder 6 , and have found that P0153 is the 02 sensor in front of cat can cause the misfire code on same side on engine which this one is , so I ordered the 02 sensor for bank 2 sensor 1 for that side as I replaced the other side bank 1 sensor 1 and it helped keep engine light off until these popped up which I cleared an so far engine light staying off again so I believe that new 02 sensor will clear the issues of these codes as wiring is good and found no shorts or broken wires but I am going to hook up my code reader an pull some live data on the 02 sensors an see if the 02 sensors behind cats are doing there job an if cats are acting right an not clogged up some before I replace muffler an tailpipes ,
I added some sea foam in oil an fuel and I am going to change oil an filter in a week after some driving, will use Valvoline synthetic oil since I dont know what previous owner used and I prefer Valvoline in all my autos,,the truck has a ton of power and really like the way it drives so far . Hope to start on some rust repair at rear wheel wells done soon and may be able to get those seat covers sometime this winter and some new carpet installed before spring along with my other project its going to be plenty of work to do through the cold spell, glad my shop is heated
