i was asking because mine went bad and is being replaced as we speak and the dealership was saying that a few on the 5.7's from 09 thru 11 and the 6.1's from 08 thru 09 have been coming in with the same problem. i wanted to see if this is true because they have had the car for a week and have not been able to get their act together. i'm thinking their bull#$% me and trying to get some of the warranty money out of me.
the only mods i have on mine is magna flows with reso deleted and a cai. i use only mobil 1 except ofr 2 oil changes where i used mobil super synthetic. they tried to bring an oil issue up saying that maybe the cause. they are now anti mobil 1 since chrysler went to pennzoil/quaker state as the supplier of mopar oil. i'm frustarted and confused by the smoke they're throwing up.
thanks i really appreciate the input. im going to create an account on your forum. unfortunately my vehicle is still under warranty and have no choice but use them.
