    Good morning Tundra Nation, I recently brought a 2016 sr5 tundra and I noticed this noise coming from the engine area as the truck warms up wondering if anyone had this issue. I’ll leave a link to the video down below.thank you.

    Sounds like a cracked exhaust manifold. Do you hear a ticking noise when you’re driving past a barrier?

    Never paid to much attention while driving, as the truck warms up that noise comes and goes. When the truck is at it’s operated temps that noise is completely gone. But I’ll definitely look into that when I’m driving

    Not an exhaust leak.
    It’s a faulty timing chain tensioner on the drivers side.
    Actually a common issue. I’m dealing with it right now.

    A lot of our Valve train parts on this engine are operated by oil pressure. I’m assuming your noise goes away instantly with a few extra rpms? You could try a hot oil flush (toyota offers a kit) and bump it up to 5w20 oil.

    If the sound still persists the next step, if this is really bothering you, is to open up the engine and inspect timing chain, chain guide, vvti and cam chain tensioner. I haven’t done this on mine yet, for a experienced tech to do this it’s about a 12-14 hour job... but from what I’ve been told 9/10 times it’s the tensioner.

    Thanks nate, yes it goes away also as the truck warms up it comes and goes until fully warm. Is this kit offered at Toyota dealerships? The noise is more so embarrassing, waking up at 0500 in Kentucky where temperatures are pretty chilly I’m sure my neighbors hate me.

    If it's the chain tensioners I'd see if the powertrain warranty covers it.

    This.

    unfortunately for me, my truck is at 120k (kilometres) so I couldn’t take it in under warranty

    It's worth'a shot, toyota has been pretty good to a lot of the members on the board, thy're very proud of the 5.7. Powertrain warranty on 20 is 5 years 60k miles/5 100 km. It never hurts to ask.

    I've got a 2016 and have the exact same issues. Find it very embarrassing at times. Same thing, loud as hell when the engine is cold but goes away after a mile or two down the road. My mechanic thought it was a heat shield but the noise returned the next day. I just read a reply that mentioned its the timing chain tensioner. I'm glad to finally get a direction on this problem and hopefully the dealership will cover it. I just hit 50k but have been driving with this issue since I hit about 35k.

    I'm having a different type of noise. 2017 CMOR 4x4. 70k miles. Like a whirring noise. Don't hear it higher RPMs, just idling.

    I have a 2010 Tundra 5.7L with 180K and it made that same sound during startups with Mobile1 5W-20 oil. I found out that the tensioner noise is due to a low oil pressure/cold temperatures issue found by changing to a higher flow Mobile1 oil filter and lower viscosity oil from Toyota 0W-20 which they use on all of their new Tundra's with 5.7L. Two years later and 10K more miles with no hearing of that sound of the chain tensioner. Hope this helps someone. God, bless all of you. Hope it works in your case, as it did in mine.

    The fix was for my Tundra was Synthetic 0W-20 oil from Toyota and Mobile1 oil filter. If this does not work you will need to replace the timing chain and tensioners as soon as possible before engine damage happens.

    The links below are for a 2010 Tundra with 5.7L gas engine. Please make sure this works for your model/year/trim.

    May God Bless you with your journey.

    Thanks, what I did was use heavier oil. It cured he problem and the check engine light went off. Switched to mobile one 5-20. Also when I changed the oil I noticed that the filter had bent over and been a bit crushed. I don't know how that happens as I am careful, but it has happened the last two changes.

    Does anyone check their PCV valves? I checked mine last week and it was stuck open. I cleaned it with gasoline and was able to get all of the carbon out. I used gasoline because of the plastic would have melted if I had used carb cleaner, because of the acetone. Here is a link to show where the PCV valve is located. 2008 Toyota Tundra 5.7 PCV Valve replacement - YouTube

    Hope this helps.
