Cold start knocking/ticking

[2002rst]

Hey all,

New member here so I apologize if this was a topic before.  I tried looking but couldn’t find.  
 

I have a 22 RST With a 5.3 and have owned since 16 miles.  It now has 6,000 miles on it and makes a knocking or ticking sound while cold starting.  I took it to the dealer and they said that this was the direct injection working under a cold start.  Let me know your thoughts.  Video is below.  Thanks!

Not DI noises.

 

Its either a lifter that isn't pumping up or has collapsed.  

 

Read this bulletin from GM 19-NA-218 - 19-NA-218 1..2 (nhtsa.gov)

Thanks for the reply.  Here is the video uploaded to YouTube.  Odd it does it only in the morning.  After sitting for ten hours at work it doesn’t do it.  Cold start is around 55 degrees to 60 degrees.  Any thoughts?

Agree with newdude, Probably a lifter.

The service advisor who I was working with was going to show to his foreman on Monday.  Kind of unfortunate how it is pretty much brand new and will have to be torn apart. I am probably going to trade it in.

That sounds like  a lifter thats ready to come apart or not pumping up correctly.Thats not a normal noise and  needs to be addressed .We have engines torn apart all over the shop and parking lot waiting for parts that we can't get. Police cars sitting for months waiting for crankshafts or complete engines that GM can't produce fast enough to keep up with the failures. Lets not even talk about transmission problems.The 6.2 engines are seizing up before the first oil changes are due!  What has become of GM. I have been a line mechanic in a GM dealer since 1975 and never seen such a poor product being put out. I was with Oldsmobile when they came out with the 5.7 Diesel disaster and also Cadillac for 23 years when they crammed the HT4100 down everyones throats. They should be ashamed of themselves with what they are producing today and charging astronomical prices for. Don't let them tell you that noise is normal.

Thank you for the input.  I am in the transportation industry and I know that there is a problem.  I understand even I cannot duplicate customers concerns the first time around.  My argument with the service advisor really didn’t get anywhere so we’ll see where it goes when he shows the video to the shop foreman.  I’ll keep the thread updated with an outcome if I ever get one.

Refrence that bulletin I linked.  They can pull it up in GM Service Information.

 

Bulletin is 19-NA-218 and here is the link to read it for yourself - 19-NA-218 1..2 (nhtsa.gov)

 

"Technically" its 2019-2020 but the description of the condition sounds exactly like what you've got going on.

@newdude commented on a post I made that sounds similar to what you’re going through. Go check it out.

Mine does EXACTLY this. It’s the exact same in frequency and everything. Did you ever find out?

 

here’s the link.

Mine ended up being a scored cylinder wall. Engine replacement. Sounded just like yours.
