hello , so i own a 2012 landcruiser with 1GRFE engine ( the updated version dual vvti) it might sound odd to some but they do come with these engines in middle east , a mechanic told me the top of the engine sounds abit off and he can hear a knocking or tapping soundhe took the cover out and said everything was good it could be from the cylender itself or th3 top cover is bent somehow and not enough oil reaching top of the engine , he suggested repair but said nothing dangerous its only the noise , i refused to touch the engine yet i wanted to post a video so you guys can check out the idle sound of the engine while hot since the mechanic told me that i kinda freaked out

Sounds like a typical 1GR to me.
I don't hear anything wrong, but it's often hard to hear details over fan and valvetrain from a typical phone video.
Sounds like every 1GR-FE I've ever heard, including the one in my 07 Tacoma that I still have. It's not a quiet or polished motor, but it'll go forever.
The dual vvti has hydraulic lifters and I agree the video doesn’t really indicate much. You didn’t mention how many miles on it?

200,000 miles +
It sounds fine my friend
sounds good to me
I think that's normal valvetrain noise, not concerning at all to me.

Engine previously opened by prior owner. Due to ticking/rattle at 1–1.5k rpm, coolant over-pressurization, and general wear, engine was fully torn down.
Findings: worn cylinders, bad piston rings, rod bearing wear, weak head gasket, worn lifters and VVT-i gears. Also small chipped areas on the outer top of one cylinder sleeve (coolant side) and a small damaged spot on one cylinder head deck.
Rebuild includes: new pistons/rings, new rod bearings, all 24 lifters, all 4 VVT-i gears, timing chain tensioner/guides, full gasket set, block and head resurfacing. The chipped sleeve area and head deck damage were TIG welded and then machined (non-combustion areas).
Keeping original block and heads. Car is daily driven only (no towing/off-road).
Looking for long-term feedback from anyone with experience on TIG-repaired aluminum blocks/heads or rebuilt 1GR-FE engines.
