Any ideas why my tundra ticks when warm?

    Happy Black Friday everyone. This is my first post on tundras.com.

    I recently purchased a 2000 tundra with the 2UZ engine.

    I replaced the timing belt, head gaskets, and related gaskets and such...

    HERE IS MY PROBLEM

    When cold, engine sounds smooth and normal... after a couple mins the right bank makes what sounds like valve train noise. It resembles a diesel engine to be honest.

    I've searched forums and videos to hunt for a similar issue and solution but nothing that matches my case.

    I did find one YouTube video that captures exactly the sound my engine is making:

    https://youtu.be/_W2My_bO7DU

    But unfortunately, no solutions posted in this video.


    Some background info, both banks were making this valve train noise, but I removed both banks cam gear caps and cleaned out the oil grooves and the left bank tick went away completely. (Why this didnt work for the right bank is beyond me).

    Oil pressure is good

    Engine oil level is good

    Exhaust manifold flange is only being held on by one nut (the other two stripped on both sides)

    Any information or advice would be very helpful as searching has yielded me no results to date.

    Thanks again!

    Not sure, but will wait to hear back from you or others on the fix.

    Either there is a bad lifter, or whomever owned the truck before you didn't perform oil changes at regular intervals (oil gunk can build up and you get ticking). What is the oil pressure like at cold startup?

    Don't wait on me Bubba, that tickin' is why I didn't get 300k out of that POS GMC. Ok it wasn't a POS, I did get 200k but it cost a transmission and most everything else. Mechanic told me to get either a new motor or new truck.

    On cold start up, the gauge reads where the red is marked...20181123_215347.jpg

    I know these aren't a valid reading for true oil pressure, but at least it's some indication. This photo was stolen from another forum to show the gauge, not my actual idle oil pressure.

    From what I can tell by the service records, (this truck was very well documented with shop paperwork receipts) the truck had very regular oil changes. When I purchased it, it ran but had a leaking head gasket to the #8 cylinder. It ran, but I didnt let it warm up due to the low coolant levels. I'm thinking this was always an issue with the truck but since I never ran it more than a min, i couldn't say.

    The part that concerns me, is that I was able to fix bank 1 after cleaning out the FIPG from when I resealed the cam gear cap. When I cleaned up both banks, i ran compressed air through the channels and passages to ensure nothing was clogged. I'm wondering if I should just ignore it, or take off the valve covers and check valve clearances.

    Sounds like a lifter going out.

    I THINK I MAY HAVE FIGURED IT OUT...

    It looks like when you remove the exhaust cam shaft you have to insert a bolt to hold the torsion gear and the stationary gear together... I did not do this... On the left bank I was able to pull out the cams together so the tension did not release. The right bank the cams came apart... thus my issue.

    How involved was this process? I have a similar sound, although mine is more obvoius when cold and when accelerating.
