Taking My ‘16 To The Shop for a “tik-tik-tik-tik” noise. Any suggestions?

[Rando Kuruza]

Those of you who thought it was normal were correct. Its not something I had heard before other than during startup so I was concerned about something worse. And since I have 85K on the LC I didn't want to ignore a serious problem before my extended warranty expired. But they service department eliminated any other possible cause and actually couldn't reproduce the noise. So I am comfortable believing it is normal. (I also had them do a fuel injection service which may help? It needed one anyway.)

Thanks again for all of the input!

I had this on my 2013 land cruiser I think it has something to do with the Air conditioner when it kicks in, the mechanism that controls the belt makes noise I don’t know the mechanics of this and how it all works, but a local shop that knows the 5.7 engine told me this is normal on 5.7 engine. For tundras, sequoia and lx570’s

Agree with what’s been posted about the 5.7 being noisy. I have two 5.7’s. Both are a bit noisy but the Tundra engine is the noisier of the two.

For some extra assurance you can do something called “Used Oil Analysis.” Basically you catch a sample of oil during an oil change and send it to a lab that analyzes the physical and lubrication properties of that used oil, as well as the wear metals and other elements suspended in it after however many miles. They then compare this to a huge database of samples from the same engine for other people and can make recommendations.

Not too expensive.. usually less than $40. But, it’s basically the only convenient way to get hard data on the state of your engine internals.
