i have a '05 srt and out of no where it is misfiring and consuming oil. ive changed the coil pack with a granatelli ingnition coil pack along with wires and plugs and it still is having the same problem for the misfire. also i dont know where the oil is being consumed from there is no signs of leaks on or near the engine block nor the exhaust. please any help would be greatly appreciated!!

 

Check coolent and see if there's oil in it,dip stick any foam or milky white paste means headgasket,just athought............

 

I've checked and no foam or milky paste the only thing is cylinder 1 & 4 spark plugs are black with a sludge like coat also 2 & 3 are white

 

If wet, possible ring (oilring/piston)
