Ticking and a misfire detected can be two different things..... personally I’ve never seen a 3.5 with a misfire code that was lifter related, and we changed quite a few lifters in that era. The roller rockers on the Pentastar CAN cause a misfire detected code.

I’ve been changing the oil on our 3.2 Pentastar every 5k.... it’s a very “busy” engine inside and it makes me feel better keeping it clean.
