Hi everyone. How do you identify the 2nd generation of Pentastar engine's on a 2014? Supposedly mid year they switched from 1st to 2nd generation which supposedly is more efficient and also has less issues with rocker arms and heads. thanks !!
Couldn’t say about how to tell the difference between 1st & 2nd gen engines, but I can tell you that the 2nd gen in our 2015 still had issues that needed to be fixed.
New cam and associated parts ran $4k at the dealer.
