Chevy Silverado lifter question (chit/chat)

I have a 2019 Chevy Silverado with 103k miles on it. I'm just starting to notice ticking when accelerating or just revving the engine while parked. I know the silverado has a lifter issue with the AFM (Active Fuel Management) system so I'm getting concerned. I plan on ordering a stage 1 cam and lifter kit with a delete for the AFM to have installed.

My main concern is that I have to travel 2-21/2 hours each way daily, mostly highway but do not want to blow the engine of course. Then is goes from a 6k job to over 10k. Am I safe for a bit if it's just a dull tick for a little bit until the cam and other stuff arrives from Texas Speed?

I've never had an engine issue on one of my vehicles before, I have no check engine lights and my oil pressure is fine according to the guage on my dash.

Any mechanics out there have some insight? should I rent a car or is it safe to drive for a few days if it's a dull tick at this point?

I'll bet money he has the 5.3 V8

GM 5.3 Liter Ticking Noise. It’s not what you think it is

Sounds like something a Chevy owner would do. SMDH…

Yeah. And a Ram owner with the hemi 5 tick 7 V8 would expect a tick and just live with it. I recently saw a video from a certified Mopar mechanic that there are 7 common reasons why the 5.7 will tick.

Why? Why do people buy Rams?

Take off the radiator filler cap and put a FORD underneath it.

Thanks. Have heard of this but going with GM and the independent mechanic for the cam and lifters.

I’ve had Ford previously as well. This is the first of many Chevy trucks I’ve had an issue with.

I’ve been down this road myself with my Chev. The first thing to do is get a Range Technologies device to disable the AFM. Others talk about this being in the hundreds of dollars but I managed to find a used one that works fine for $40.

If you do end up with a stuck lifter, keep one of these links handy... quite interesting as a fellow has a way of getting them ‘unstuck’ without an engine teardown.

Another link to keep handy....
https://www.lt1swap.com/afm_delete.htm This is the website of a smart dude in Missouri who programs ECMs to disable the AFM and does so quite inexpensively....

Best of luck with this.

Thank you. I did see that video a couple weeks ago. I figure that’s a temporary fix and since I run a business out of my vehicle I’m going to replace everything and start fresh with a little more hp and a throatier sound coming out of my HDMI exhaust system.

I bought a used 2011 Silverado that had just had a new engine put in at 100k miles. After finding out about the problems with that active fuel management (is that what the thing is called where it goes from 8 cylinders down to 4 cylinders?) I sent in my computer to some guy that disabled it. Now it runs on 8 all the time.

It wasn’t that much to disable it. Maybe $50 to the guy, and another $50 to FedEx. Probably isn’t worth doing on an old engine. My truck had a new engine with only 8000 miles on it.

My 2001 Chevy had the lifter tick fairly soon iirc. The mechanic said it wasn’t that big of a deal. Hit a deer at 160,000 miles and totaled the truck. Got rid of the tick.

For the active fuel management they say that the ticking is caused by poor lubrication when the 4 cylinders get shut down and something wears out on those 4 cylinders.

Wow that’s cheap. The going price around here is 500 dollars. I’m going to attempt it myself first.

This is the product I purchased. Have heard the customer service there sucks but the guy I spoke with was awesome. He setup the shopping cart for me while we talked in the phone and then emailed me the link. Easy Peazy.

That’s hilarious....only thing I could match is the throaty sound.

My 5.7 Hemi Ram has 300,000 miles on the original motor and no tick. My Hemi Charger has 250,000 on it, no tick. Good oil and filter at 5000 miles, limit idling, and enjoy the power.

Most ticks are broken exhaust manifold bolts. A very small percentage are lifter/cam failure, mostly from excessive idling. Because the repair cost is so high, a lot of noise is made of it.

Ram owners know to go to the Ram Forum to get vehicle specific advice,

[TermLimits4All]

Yes. I have a friend who also has that problem with his Ram. My lifter problem has been confirmed by two shops. One was the GM dealership, the other is the company I’m using for the install. I’d do it myself but there’s so much crap to disassemble just to get to everything. Plus I’m not as strong as I used to be and don’t want to risk messing the job up or messing myself up.
