Any Intermittent lifter issues?

[Billet Bowtie]

I have a 2019 6.2 High County. The other day I had a bad lifter tick. I drove the truck probably 30 miles or so cutting it off and on a couple of times and after restarting the noise was still there. About the time I pulled in my driveway the noise was gone and it hasn't done it since. I know there are reports of collapsed lifters I just haven't seen any where the lifter sticks and then becomes unstuck. It never threw a cel so I am assuming taking to the dealer will be pointless.

My 2021 5.3 with DFM started with an occasional banging up front and then lifter noise. The next day I drove 5 miles to the dealer.

During the drive I had various unrelated trouble codes on the instrument panel. During the last half mile all symptoms went away and I accelerated to 50 mph with no issues. When I got to the dealer they scanned the engine and said that a lifter had either failed or there was an injector failure. The service writer said he was pretty certain it was a lifter. They gave me a loaner and kept the truck. They called later and said one # 4 lifter had failed and bent a pushrod. All 16 lifters were replaced an one pushrod at no cost to me.

 

If you still have a powertrain warranty, I would go to the dealer and get this diagnosed.

Thanks. I think my biggest issue is it never threw a code and now two weeks later it has not done it again. Time will tell.
