    I just purchased my first tundra. It’s a 2016 5.7 with 75000 miles and I can’t help but notice a slight tick or knock much like a diesel would make. It’s very faint but enough that I hear it. I hear it mostly in the cab of the truck and underneath behind the engine and in the exhaust.

    is this normal? Am I paranoid or should I be concerned?

    My previous truck hand a loud exhaust and all kinds of noises so when this nice quiet tundra it stands out to me

    I've got a '15 5.7, it is very quite at idle, I mean there are lots of moving parts in there so there may be a 'tick' but no knocks. Maybe you can post an audio file for folks to listen to?

    Well then it probably zero problem, just a quiter exhaust so other sounds are more noticeable.

    Depending on how one feels about oil additives, I've used several different Liqui Moly products. This one aims to quite engines down: https://www.amazon.com/Liqui-Moly-2...586922379&sprefix=liqui+m,aps,196&sr=8-2&th=1

    I also use another Liqui Moly product, Ceratec, it added 4/10 of an mpg to my 5.7, not much but i like the idea things are spinning more freely in there, haha. Luck with all things.

    loose heat shield? if you hear it more underneath than you do in the engine bay, that's what I would check.

    I have a 2014 I believe is a flex fuel engine and hear the same thing. I also notice what I think is an exhaust manifold leak on cold starts when it's in the 20's or colder. It sounds like a loud knock for 1-3 seconds, I mean LOUD. I know dodge hemi has been known for that same issue. I heard it while test driving a brand new ram a few years back. If it is the exhaust has anyone had this issue? Has anyone put a set of long tube headers to fix this issue?

    Normal sound for this 4 cammer engine. Run 5w-20 or 5w-30, and things will quiet down slightly, but really nothing to worry about.
