So, I've had a ticking noise for the last 10 months or so. Very VERY annoying and I can't seem to get rid of it.
I have a parallel thread on mkiiisupra.net, but I am getting really desperate for a solution.
Summary:
The tick came after 3-5 months.
1. Engine started to tick, sounds like valves
2. Local non-brand mechanic thought it was valve too.
3. Toyota looked at it and refilled some oil; amazingly the tick disappeared!! Coincident or not, I don't know.
I drove the car since the tick was gone. This lasted for a few weeks.
4. Tick came back and I tried to refill some oil; sound still there.
Since nobody could help me I still drove it about, making sure oil level were good each time. No loss of power. About 3-4 months later BHG!
5. Got a spare engine from a friend, sent the head to mechanic for overhaul. Switched my old head with the new head; hoping the tick would go away (if it was a valve), but tick is still there.
Had a few leaking issues, faulty timing etc. etc. but they are all worked out now except for ISCV, Speed-cable and this fucking noise!
5. Removed timing belt cover to check cam wheel location. Started the engine with the timinig belt cover off; ticking sound was louder.
6. Removed the lower time belt cover; nothing abnormal found.
7. Tip about loose manifold studs could cause noise. Took the two studs out and started the engine without, noise could now be heard when engine starts 0-1200 RPM (this could be a coincident as I only started the engine once after removing the studs) and as before when revving 2000-3000 RPM.
8. Time-sert'd the two studs and torqued all studs to 42-44 N-m. Noise is still there unchanged.
About the tick:
- The tick has come from engine startup only once (I didn't start more than once so might've been a coincident) from the startup range 0 to 1200 RPM. This lasted for half a second and was gone straight after.
- The tick (besides from the above) can only be heard in the range inbetween 2000 to 3000 RPM and only on acceleration. No sound can be heard on deacceleration, under 2000 RPM and in high RPM ranges (above 3000).
- The noise sounds louder when removing the top timing belt cover. But I am pretty sure it has nothing to do with the valves as it is not even the same head I started with (see point 5).
Startup stage of noise from point 1 to 3 (noise differs from the others, which leads me to theory 1):

Middle stage of noise from point 4 to this day.

Theories:
1. The ticking that started was actual a valve tick. Since oil helped and removed the problem, I might've had low oil levels. However, I was too frustrated to find out and ask the Toyota mechanic.
2. I'm fucked!
3. Blocked oil feeds/lifters.
4. Loose bolts on the flywheel?!
5. Exhaust manifold studs. (I think we can clear this one out)
Additional information:
- There has been no loss of engine power AFAIK.
I am really desperate now. This noise haunts me in my dreams! :icon_mad:
