VVT-i Startup noise

VVT-i rattle at cold startup, caused by lockpin inside camgear not being properly unlocked at startup. On the restart the noise is gone, because oil pressure inside the camgear was built and unlocked the pin.
This same lockpin issue will cause rattling at idle and low engine speeds. You can hear that in my other video.

I have the same problem :(, I've had some mechanics look at it that race celicas and he said is the timing chain :(

@sufgods

I've seen many mechanics with this diagnosis and they try changing the chain tensioner or overtightening the timing chain to no avail. The only fix is to get the updated VVT-i camgear.

i saw many to but non around here knew what to do so i found an easy fix, after replacing the engine and everything in there.... buy a new car haha been a month and have had no problems ;D just the way i like it ;D

i get this too sometimes on my toyota voxy.

it has a 1az-fse 2L engine.

i get the startup problem about once every 50 times and idles same as your celica.

there was also some sludge in the engine when i bought it but it's been 2 years now and the noise got a little worse.

i also tried cleaning it by changing the engine oil every 3000-4000km.

the oil now stays clean for 5000km but the noise is still there so i guess i need to get a new vvt-i soon.
