Strange noise

[V1ZR1]

I’ve been very reluctant to post this and am concerned knowing the issues the new engines have had but I hear this strange noise occasionally and the information I have seen on Google seems to suggest it’s related to the lifters.

I bought my 6.2L V8 2022 with 9,000 miles on it and it now has 25,000. I have put premium gas in it for 13,000 miles. I have kept up on maintenance.

I added a Borla exhaust, a K&N cold air intake, and an oil separator.

Anyone know what could be causing this and if it’s something I can fix.

Might be lifter or motor failure. Have you had the recall service done? They have a 10 year 150k warranty now. I would just take it to the dealer and get a proper diagnosis.

Based on the info I’ve seen there are no open recalls for my truck. I know I bought the best warranty available when I purchased it. I will take it to the dealer though to get a proper diagnosis and thank you for your response!

I have a 2022 and mine was part of the recall and pico test. Not sure why yours did not meet the criteria. I would check with the Dealer. They changed my oil to a different more expensive oil.

Is your heat shield around the spare tire making contact with the exhaust pipe? That noise sounds more like metal on metal contact from loose parts. Hard to say for sure.

Thank you. I will let the service writer I have trusted for years know about this on Monday and hopefully there’s something to be done.

Just for reference had the same noise, discovered heat shield under cab stud nuts were loose. Took to dealer twice before instructing them to glue locknuts on to the studs that hold the shield up. They finally did have not heard it since. I did however have to retrieve the heat shield on my 2nd visit off the side of the highway when it literally flew off at speed, scared the resolve right out of me and onto my service guys desk

Thank you for this info. I spoke to the service writer yesterday and he couldn’t definitively say it’s the lifters so I will pass this along and see what he says.

It's the heat shield at the bottom of the header...mine did the same exact thing.... Either they don't know what loctite is or they don't know how to tighten a bolt

It’s literally welded to chassis thin metal studs not threaded and they spin on those cutting nuts that are supposed to create their own thread at install. They’re chickenshit mild steel thin gauge press-formed nuts (garbage) unable to withstand heat, vibration, or hod forbid a bit of dirt off-road

Here is the piece I was speaking of....

When they replaced my CATs under warranty the tech didn't even put the fastener back on....it just laid there on top rattling around

Oh mine was the flat shield under the cab further back I’m on my 4th one

Yeah but they saved $0.15 x 5,000,000 million trucks for $750,000 to the bottom line.......those crooks know math, but not mechanics.
