    Just changed the oil in my 2017 4x4 sport today and after starting it back up I noticed a pronounced knock coming from the engine.. anyone know what this could be? My baby only has 35,000 miles and has been very well maintained.

    I too had a similar issue that I ended up taking my Tacoma into the shop to have examined and was told that this is normal due to the new 3.5 fuel injection system.

    Mechanical fuel pump for the direct injection are noisy(knocking sound). It's hard to tell from that recording, you need trained ears to verify.
