Houston Mechanic Reccommendation? - 2017 Chevy 5.3 ticking

The 5.3 on my ‘13 Suburban is doing the same thing.

Did you lose pressure? Oil pressure is fine right now.

Know nothing about them but Michael Berry talks about them.

I drive a 2002 Chevy with 5.3 as my daily driver, 370k miles. I bought it new. At 200k miles my lifters starting tapping loud. Like had to turn off at drive thru to order loud. I talked to my mechanic and he suggested swapping to shell rotella. Heavy duty diesel oil. The ticking went away totally. I change oil since then every 5k miles and filter every 10k miles. No issues since. 5.3 is an amazing engine.

CAFE killed it with AFM

Mine did this at 100k miles. Like 105,000

Barely out of warranty.

I was quoted around $4k in 2020 because they have to fix them all or you damage cam shaft and it’s basically totaled.

I sold it.

Literally the same truck as you. And I’ve warned others.

PS: a mechanic told me to sell it because he had seen it with almost every 5.3L Chevy from that year. I straight up told the dealership salesman that sold it to me…that he sold me a lemon. He just put his head down.

Also, when I sold it, I traded it Toyota Slidell for full carmax value without the lifter cost. Tells you how much it would cost them to fix it in house.

I actually just got my 2018 Yukon Denali back from getting a full AFM/DOD delete last week. I plan to do a larger writeup about it but if it's a simple tick, it could be one of your standard lifters. However, if the tick becomes a tap and you get a cylinder misfire warning light, you have a collapsed AFM/DOD lifter that will remain collapsed until you have someone pull the heads and get it out. Here's comparison to a normal hydraulic roller lifter versus a AFM/DOD:



I bought that Yukon with 97k miles on it (in fantastic shape) and knew those lifters are just ticking timebombs and a question of when they will actually collapse and not come back. So, I bought an AFM/DOD delete kit from AMS Racing and it included a Brian Tooley Racing camshaft and lifters of your choice. The truck runs great and the engine should go the long haul like I plan to use it.

H Town is a big city. What side of town are you on?

Lot of mixed reviews here. I had an engine light come on but it went away before I could bring it somewhere to pull the code.

I went ahead and put sea foam in the fuel, and I may try the heavier oil weight. Would hate to have to sell it and buy something else right now. Only have 130k miles on it now.

I had an 05’ Chevy Z71 crew cab with the 5.3 purchased new that I ended up trading in with 220K miles. Loved the truck. Three biggest issues were 1) Check engine came on around 35K miles, throwing a code for knock sensors. A faulty design in my opinion, the sensor was located where water accumulated on top of the block. 2) had the ticking from the lifters which I chose not to do anything about but it was annoying. 3) for some reason I went through hub bearings more than any other vehicle I’ve ever owned.
