spark plug failed and dropped guts into cylinder.. mopar says tough crap. So we have the lifetime warranty through mopar because the last ram 2500 with the 6.4 was a lemon (2014) anyway. Truck has 130434 miles and change oil at 10k on the dot, all other maintenance done as scheduled smd wouldn't you know it. At exactly 100k I changed the plugs with autolite platinum instead of the champion that was in it. Now at the 130k I have a failure where the bottom of the plug fell off into my cylinder and scratched the walls a little, and the service writer says it bent my valves.. so there answer is a new long block for 10 grand.. (no way) said my warranty will not cover any iif this because iif a non warranty item failure (the spark plug) I contacted autolite and they told me to ship them the spark plug immediately. So now i'm in the waiting game in ups to get that plug to there engineers and i'm sure someway or another they are going to tell me though crap like the ram dealer is already. I'm scared to call them for this reason so far. You could actually spin the spark plugs porcelain in circles while holding the threaded part.. crazy I know. And even crazier that this happen to this truck that ran perfect for the entire life until now. Does anyone have suggestions on how I need to bark at and who on this? Or just tru to be patient and accept whatever they say? This is a mega cab 2016 ram 2500 with the 6.4 Laramie. It's my work truck and I work in the oilfield. I've only had this truck about a year and 8 months and did not it new along with the full bumper to bumper warranty for mopar (not a side show warranty company) I can only use this truck for 70,000 more miles on the job before I have to upgrade so the new 10,000 dollar motor is not a option unless they give me a brand new dash cluster also, otherwise my job will not accept it over 200k... please help..
