    Update to my issue.. Decided to do an engine flush with Liqui-Molly Motor Flush and fresh 0w20. Thought issue was resolved as it didn't produce the same noise for 2 days. But today, its wet & cold.. Squeak at cold startup came back. Threw a P050D Code for cold start. My new theory is a possible bad injector #4. If I run ODB Torque Check dongle on it, in testing I go get some misfires on #4 & #5. Only a few. like on a 25 mile trip like 15 misfires on 4 and 7 on 5. So I'm not sure if that's the issue or what.

    Have the same issue on my 2014 Silverado 5.3 - 89k miles. Both your videos sound EXACTLY to mine. Chirp lasts for about 10-12 seconds then dissipates. Mine appears to come from the passenger side back of the engine. I've chalked it up as a lifter. I'm concerned as it appears to get louder on certain mornings. Depends really on the weather it seems. I've tried some Liqui-Molly Lifter additive, and that didn't do anything. I was contemplating an engine flush at the next oil change. My theory is the oil at 0w20 is so thin it drains off the lifter, then takes a few seconds at engine start to coat properly. Again, this is just a theory, I'm not a master of mechanics! I was also thinking out trying a little thicker oil during winter months and 0w20 during summer. But I won't know the thicker oil theory until next year.

    The add-on bracket evidently is a GM quick fix.. Where the bracket holds the two high pressure lines together. What it "supposed" to do is probably stop or limit the vibration of the HP line that has the elbow in it from vibrating. Without it, the elbow will over stress and eventually crack, like mine and many others have done. Check out Sandy Blogs for the placement of the bracket. http://sandyblogs.com/techlink/?p=3816 Your can find them on eBay and add it yourself, it's pretty simple after I saw how it was added. eBay has them as cheap as $4.. http://fave.co/1pj4AKs

    Just want to add that I went to my Local dealer to get this fixed. Changed the condenser line, added the bracket, vacuum and recharge. Unfortunately I'm out of warranty. Total cost $308.

    Just passed 36k about a month ago on my 2014 Silverado.. Figures... Now have the same AC condenser line issue. The green fluid is slowly dripping at the elbow, and just to the side of the elbow, I can see pressure leakage there. I've searched around for this service bulletin everyone talks about, but can't find it anywhere. I'd like to bring it to the dealer or local ASE garage. I checked safercar.gov with no luck. Does anyone have a direct link or download to this bulletin? I've read it on Sandy Blogs, but that still tells you to refer to PIT5331 for parts.. repair bulletin PIT5331//OP.CODE 4415010
