I only have 7K miles on my truck and I have a ticking noise coming from under the hood.  Sounds like a loose rocker to me.  One guy said  that the injectors on the new GM trucks make this noise?  ???

hi Corey  68,

 

My truck has almost 4000 miles on it now and I haven't heard any noise under the hood. There is an anoying rattle under the dash which I'm gonna have to find. I hate rattles.

My 6.0L has a constant tick from the rear of the motor.  I know it's not the rocker arm/needle bearing thing that everyone is talking about....

 

Mine is deeper in the block, and I've mentioned it to the dealer once before...  I'll mention it to him again when I take it in for my State Inspection...

 

BTW, My motor sounds better after I've run it hard...  So I'm baffled about this one...  If it was carbon buildup, then the noise would be on the top of the motor most likely, and would burn off with some abuse...  but my noise is definatly deep in the block, most likely around cyl. # 7 and #8.

Doesn't that sound like the infamous piston slap that others have near #8?  A guy named Gixxer over on pickuptruck.com had his 6.0 replaced under warranty with a new 03 engine for that or something similar.

My 6.0 liter makes a ticking sound when it is cold and lasts about 30 sec to 1 minute. It has done this since new and has 13,800 miles. Since reading the posts on this board, I have decided not to take it to the dealer and chance having something else go wrong. This truck totally kicks a$$ and I'm not going to worry about some ticking when it is cold!

I agree with you in your case, but some of our GENIII's tick all the time, hot or cold, sounding like it's in the bottom end and not carbon buildup nor the lifters, injectors, nor any other top end component  :(

Markeaux,

 

Sorry, I thought you guys were talking about when the engine was cold. I would take mine to the dealer if it ticked all the time.

I know there use to be an additive GM dealers sold called EOS and if I remember there is a newer version additive that would probably fix this clicking....worth a try. :(

Yeah , mine is the same as Bob G. only when it is cold, and for about 30 secs or so, I am running 10w30. Do you think this could be a cause? I doubt it, My buddys 5.3 ticked really nasty and he put some good fuel injector cleaner in it before a hard tow and it really did quiet it alot, I think I'll try some good brand of the cleaner next tank, I have heard of some chevron brand, wal mart has some for like 6 bucks, says it is good for like 12 gallons of fuel?? It did wonders for his truck, funny , last winter, not start up tick, this year, have the tick, also alot colder this winter, any comments? the 6.0 does run well for me.

My 5.3 in the the PU and the 6.0 in teh Escalade both ahve a slight tick.  The 5.3 is alot worse.  The dealer said it was the valvetrain.  Its leased so I 'm not concerned.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
