Nah That would be great if 2 conditions.....my noise would go away after warm up and..... plugged the exhaust forcing it to go somewhere else (like the crack) but nope....so that is ruled out.
Interesting. Does the tick come from one specific side or from the front only? Do you notice it more with the window down or from in the cab? Sounds like it does it when the motor is warm or cold right?
The tick comes from the drivers side. I used a "special" stethoscope and have pretty much located it to the the second cylinder from the front. Of course I notice it more when the window is down. Even with the windows up it is still a distinct sound without the radio on. I have tried to always have the radio on so I wont hear it but it is always there when I turn it off. The sound is there warm or cold as well.
I have "the noise". It almost... sounds like light dieseling on a cold start-up. It does not occur at cold idle (in park), however, when I put it into gear (D, R, etc.) there it is. It lasts for about 2-3 minutes max, then nothing. Very, very quiet after a minimal warm up. The vehicle runs great (2004 Sequoia) with 138,000 miles. I bought it at 110,000 for c-h-e-a-p and it's been very reliable.
I have tried fuel injector cleaner and higher octane gas, no change. It has a new timing belt. At this point it's almost a "that's the way they are, don't worry, be happy" thing. However, I am very willing to stand corrected if anyone has another perspective.

Most likely your dealer need to take valve cover off and check clearance between cams and lifters. That does not take that much time (max 2 hours total). Once they do that, they can tell you if you need to replace shim/shims. I am doing this process on my tundra now. Each shim comes around $6.50 and your sequoia has 32 of them. There is possibility that one or two of them need to be replaced.

enjoy,
The noise I have with my '00 Tundra is exactly as you describe. On mine, it comes from the pistons and has gotten slowly worse over the last 10 years. I'm at 85K now, and found out that it helps to run the engine a bit longer in cold weather before putting it into gear - otherwise it will knock pretty loud (not good!).
