Hello Folks. How Do I Know What Engine Model I Have ***LFX***? I Have a 2014 GMC Terrain SLT2 With a Build Date on Door Sticker of 10/13 Any Help on the Improvements/Modifications During Manufacturing Would Be Appreciated. I Thought I Read Somewhere They Put in "Improved" Crank & Main Bearings & Improved Fuel Rails But, Don't Know What Time of the Year (or) Engine S/N's the Improvements Were Made Also (if) Someone Knows Where to Find Engine Data/Block#/Engine S/N. It Will Be Appreciated. Thanks to All That Respond.
