Toyota Premio 1.8 strange sound when accelerating

[furqanalighazi]

UPDATE # the sound came from a faulty water body as the temp rise it produced sound.

I am not an expert but it seems like broken crank... Hope it not

AOA. Ramazan mubarak to you all. We recently bought a Toyota Premio and i changed its cvt oil and did basic tuning like cleaning spark plugs throttle body cleaning and oxygen sensor but upon acceleration of car it produces "krrrrr" sound not in neutral but in D or S. Whenever the car is accelerating in 3-4 rpm it produces the sound and when the car is driven on low rpm it does not produce the sound. Also the sound is coming from the very bottom of the car not above. (i think from gearbox area). I checked the oil it is ok and also some otherthings they are also fine but the sound is still coming. the sound is not of knocking. will be looking for suggestions about the problem Regards. will upload the audio of sound as well tomorrow as the car is not with me now. the oil i used was silver tin Toyota original cvti oil 4L

Which Model Premio??? It Was CVT???

Seems Like A Loose Part Or Mishandled Oil Change Procedure

I am not an expert. And bro you definitely have a lot more experience.
Karr Karr sounds on acceleration about 2, 3 rpm and from the very bottom of engine bay a considered as a definite sign of broken crank. (as my one crank broken experience).
But definitely as you are a more experienced and informed fellow, you can shed some light on it way better then me.

Makes No Sense That Everything Was Fine And SOund Appear In Engine After Gearbox Oil Change.....So Its Def Related To Gearbox Not Crank Unless It Was There Before Oil Change.....Crank Wont Break...Its Bearings Develop Noise So That Sound You Mention Is Of Rattling Rods Bearings And It Wont Go Complete Silence On High Endd Too...

not rattling noise... yes it was fine before the cvt oil change when the old oil was changed it was very dark in colour meaning was very dirty... the oil which was taken out of car was approx 3.35 liters and we put around 3.45 litters of oil

[furqanalighazi]

also there is no noise under neutral and park even if it is rev'ed hard from 0-7 rpm rapidly but sound appears under S gear but not very much audible in D...

[furqanalighazi]

also is there any possibility of tappet sound??

Seems like their is a fault in your car transmission.

Same problem here
Altis 1.6 auto 2012 car is also making Krrr krrr sound but on low rpm between 1200-2000 but not in neutral. Shown to Toyota they r say it's due to timing chain & should be changed
Do any idea?

no brother toyota indus checked the gearbox it is fine i have put my 3 days in finding the noise but still not found also the mechanics of toyota indus told me it is not a very big thing as lot of japanese cars have this sound but i did not agree with them... they told me that to get the tappets capsule cleaned it might be blocked for some reason...

Get your tappets capsule and timing belt inspected, It might solved by this.
