Hello all, First let say thank you for anyone who can possibly help. I'm pretty frustrated as of right now, trying to run this down. 2014 Sierra 1500 5.3L All Terrain 125,000 miles Noticed a whistle/whine coming from the engine bay, but only when under load (won't do it in park), and accelating (stops as soon as I let off the throttle). I first noticed it when I was towing, but now does it everyday. It seemed to go away after the engine got warm. However, it seems to now be staying regardless of temp. So far I've: Changed all 3 belts, replaced the alternator, used a mechanics stethoscope with no luck. So my questions beyond what do you all think. 1. Could this be coming from the PCV tube being worn? 2. Where else should I look for a vaccume leak? 3. Literally anything else you may feel as pertinent, please let me know. Thanks Again, CG
Has anybody done a muffler delete then moved onto the GM Borla? I just traded in my early 2014 5.3L Denali to a 2016 6.2L Denali. I had Borla S Type on my 2014 5.3L and loved the sound around town but couldn't stand the constant hum on the highway. I just did the muffler delete on my 2016 6.2L and like the sound and how silent it is on the highway. But I do miss the Borla sound. Is the GM Borla just as quite on the highway as a muffler delete with flapper open and resonater still in the chain? Thanks!
