I Review a 2022 Chevy Silverado 1500 with the 5.3L V8 LS Vortec gas engine and explain the top 5 issues with this engine. I explained the major issues and problems with these 5.3 liter LS v8 engines over the years and detail what exactly is causing these known issues. Is the 5.3L v8 Chevy engine a reliable engine?



I hope everyone is having a wonderful week! As I mentioned at the beginning of the video I was hoping to have a ram 2500 with the Cummins this weekend but those plans fell through so I got this Silverado and figured I could talk about some common issue with this very popular v8 engine.

the so first major issue and what I think is the most important issue is the lifter failures on these engines. it all seems to stem from the active fuel management system or the cylinder de-activation system which uses engine oil to control the lifters. what can happen is those lifters can become stuck and ruin your cam shaft. this is an expensive and time consuming repair and the worst part is the newer trucks seem to be more prone to this large issue.

the second issue on the newer trucks is the consequences of having direct injection fuel system. this can result in carbon on your intake manifolds and valves from your EGR. the second issue is that the injectors seem to be failing at a faster rate then the 5.3 v8 engine that are not direct injection engines.

the third issue has to do with the second gen 5.3L engines. Oil Consumption was a huge issue for these engines and there is a class action lawsuit still again gm for this issue. basically the cylinder de-activation was letting oil pass through the intake and burning it. the other issue with heavy oil consumption is that your spark plugs will foul pre-maturely.

the fourth issue with these engines is with the 1st gen. they would have heads crack and internally burn coolant. they also would have intake manifold gaskets fail. but that seemed to be more based on longevity of the engine.


Those are some of the major issues with this gm 5.3L LS V8

As always I hope you enjoyed the video!
