I review the Chevy/ GMC 1500 5.3L V8 engine lifter failures (Engine Tick/Collapsed lifte) as a heavy duty mechanic. I go over some history of the 5.3L V8 engine and dive into what is causing these lifter failures, both Active Fuel Management and Dynamic Fuel management. I explained what GM service technicians have said about the issues and give my input on how to potentially avoid this engine issue.

Hope everyone is having a good week so far! I wanted to cover this topic because I think the lifter failures on the chevy 1500 5.3 L and the chevy 6.2L engine are really starting to become a much more main steam issue. they have been problems for some time now but it seems with the recent implementation of Dynamic Fuel Management - GM's updated cylinder deactivation technology that this problem has become very large.
so large that that in 2022 there was a class action lawsuit against GM and people are really starting to take note on these lifter issues. I think it is unfortunate because the 5.3L V8 for years was an incredible engine, reliable and could make tons of power. but it seems like those days are over.
Now in 2022 GM also released an updated lifter but talking to some GM technicians this is not the first time this has happened and they suspect this won't complete solve the lifter issues.
good news is statistically speaking if you own one of these engines you are much more likely to have a good running engine then one that fails due to lifters.
the best thing you can do for these engines is to get a tuner that deletes the AFM and DFM. this is dramatically lower the chances of lifter failures but may void your warranty in the process. the other recommendation I would have is to use high quality oil and change your oil on a good timely basis. these lifters run on engine oil and having clean engine oil is essential.
anyways guys I hoped you liked the video!
