Timing chain milage

[GRam1500]

Hey all, on the 2019 5.7 gas vvt engines what are the owners finding themselves changing the timing chain and parts? I m looking at a 2019 with a 110k on it? Thanks

Wait till it has cam and lifter issues,then change the chain,no point in doing it now,as the chains in the VVT engines very seldom give trouble

Its runs smooth, when do the cam and lifters go? They are not roller?

Can't really put a time or milege number on the cam issues,alot depends on how well it was maintained and how it was drove.Hemi's are not an engine that likes to be drove by Grandma,they prefer to be drove by a 16 year old .
Yes they are a roller cammed engine,have been since they were introduced 23 years ago,but they are notorious for having cam and lifter issues.

Whenever they want.....lol

Seriously, there have been failures sub-100k, but that is rarer. Engines that idle alot and/or longer oci's seem to be more likely for failures.

Mine went at 201k, but I had <8.5% idle time, too.

Here's my chain guides at 201K miles, hardly any wear. I could not find anything wrong with my chain, timing sprocket, or cam phaser either.


I went ahead and replaced all of them strictly because of my mileage and because I didn't want to have to go back and replace something I didn't do, since the engine was already open.

I recall we used to upgrade the entire timing set package back in the day to the 6.1 timing set package for the 5.7LX/LC platforms when doing cams, etc.

Do you know if the 6.1 upgrade is applicable to the HEMI 5.7's in the trucks nowadays?

6.1's don't employ VVT. BlackBird and Smith Innovations do have an upper gear that does away with the VVT phazor for the later VVT engines, that's very similiar to what they used to use on the early 6.1's though. That's if you're running a big enough cam to require a VVT lock out
