It’s located between the chassis fuel line and the high pressure fuel pump.

 

It seems to have done the trick on mine. I’ll keep you posted as I drive it throughout the next week. The TSB was PIP5395D.

My 2014 Silverado is at 120,000 and running just as good as day one, not one issue with it. I know there’s problems out there, but complaining to others saying “should of bought a ford” doesn’t help

You'll be leaving blue oval quick enough.. they are not any better.

Just got this from a buddy at my local dealer. Looks like Chevy is aware and they are working on a fix. Sent from my iPhone using Tapatalk

Is this the same tick that everybody else is experiencing? I have a 6.2L 

 

 Dealer said is it fuel injectors but the tick gets faster at higher RPMs and when I let off the gas at a high RPM the tick remains fast and doesn't slow down so I don't think it is noisy injectors because the tick would have slowed when I let off the throttle.

Hey Parker, any updates on if the tick is gone?

The tick is mostly gone. And by that I mean that I can hear it very faintly once in a while but it seems that it goes to V8 mode or upshifts right away. If I didn’t know about the tick I wouldn’t know it was there. Much improved!

thanks for the info, I think I'm going to head to the dealership soon. I've been convincing myself some days that its fine and other days it bugs the hell out of me

I'm the same way.....I'm sure it's just as noticeable every day, but there are days I really notice it and days it just must blend into all the other background noise

Yeah and also partially because I'm a little reluctant to get into it with the dealership. first try to explain it and hopefully replicate it for them during a drive, then also going through the procedures of them wanting to replace/check other things like the valvetrain or exhaust even though people have confirmed that it wasn't the issue. I was going to wait until there was a clear cut "fix it" answer that I could bring up with them, so maybe this TSB is it

I have noticed that when I hear the tick if I pull a hard left or hard right (I mean really hard) the ticking stops while I'm turning. I tested this going 40 MPH in manual gear at 4k RPM on a two lane road. I was in the right lane and then pulled hard left all the way to the left lane. The ticking was silent until I straightened out.

It’s jostling that causes it to come and go. I’ve had to slam on brakes before and that caused it to start then I hit a bump later and it goes away. I’ve heard it ticking and then just completely stop out of nowhere

So there's 18 pages of this but it seems like there's many different parts that were replaced. We still don't know exactly what it is? 

 

Just like the other two posters earlier today, I'm reluctant to go to the dealer because it's an entire day of my time and they'll either say it's normal, can't reproduce, within specs,  etc.

I decided to finally call a dealership yesterday to make an appointment, one that I've had good luck with service before even though its a different one than where I bought the truck. I'm just hoping that the tick will be audible that day, and I'm still debating on whether I want to mention the TSB or just let them go through their own process without my input

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
