Ticking noise after timing belt change

2006 tundra 4.7 v8 I changed out my timing belt and tensioner due to right camshaft being one tooth off timing, after replacing I start up my truck and it has a pretty noticeable ticking noise not the fuel injectors I rechecked my timing and it seems to be good? What could it be

 

The Internet seems to think it’s your hydraulic tensioner. When these guys wake up and start commenting they’ll get you zeroed in on most likely cause real quick. I just did an Internet search which indicated the hydraulic tensioner as most likely cause.

 

...or the tensioner bearing,
...or the idler bearing,
...or the water pump

For ~ $150 I would have bought the Aisin kit and replaced all those things while it was apart, because why not?

 

I think if you started a poll today about "who with the 2UZ-FE hears rhythmic ticking when their engine is running", the responses would show you at least a 60/40 split, where 60% hear that infamous tick. I wouldn't be shocked if it actually clocked in at 80/20. The cause is speculative, mine sounds like a sewing machine (81k original miles now), sounds like lifter to me. Some, like @Weagle have actually had their ticking disappear after a full tensioner/timing belt/water pump/pulleys overhaul using the Aisin kit (IIRC).

Let me ask you something: Did you pull your negative battery cable for at least 10 minutes during/after the install, forcing a relearn to happen?

 

Too funny…. I have the 4.0 6 cyl in my 4Runner ….. now that’s a loud engine!! That ticking noise has become so second nature I no longer even hear it. I was amazed at how quiet this 4.7 V8 is. I remember watching CCN and him trying to tell his viewers the sound of a normal 4.0 6 cylinder and one that really did have an issue. (Which is how I learned what warrants further investigation). I was under the assumption that OP has an obvious issue sounding tick…. Not the normal type…lol

 

The tick I hear on mine sounds like valvetrain chatter to me, I was surprised after seeing other people post videos on this forum and one other, and it sounded nearly identical to mine.

Then another person posted a video from one of the earlier years which, once again, sounded similar to mine, a bit louder, and it was identified as the infamous earlier-year exhaust manifold broken stud leak or cracked manifold, I forget which.

I've heard it's just noisy injectors.

I dunno what to believe.

 

yes I pulled the battery while doing the job the tick sounds more stronger then usual
Here are some videos of the tick

I’d definitely classify that as not a normal tick. I hate to say it but to save allot of headache, I’d repurchase a new AISIN Kit and re-do the timing belt, water pump, etc…. That’s just me though. Some of these other guys are better at trouble shooting.

 

Am I correct that 2nd video is without the fan installed, and no serpentine belt? i.e. that effectively rules out the ticking coming from anything on the belt drive line, and the fan making contact?

 

Yeah no serpentine belt was on, so I guess I’ll have to buy a Aisin kit and redo it then hopefully thats fixes it

 

Wait ... why? It looks like you have a factory belt on the truck currently, is that what you just swapped in?

When you checked the timing did you use THIS METHOD?

I'd want to throw a stethescope on it to figure out where the ticking is coming from before I went that far. What if it's the belt skipping against a harness? Or one of the pulleys making a single contact per rotation on the cam sensor and/or its harness?
