Asal may ya hyundai 93 excel (nawaz shareef sckeem ) may lagaya han used may laya ta satrt may sahi ta ramzan say 1 month pehlaya lagaya houa ha ..

sound vanishing at rpm increase & no issues after warm up.

change the OIL Filter to OEM NEW , if the issue pop again ask your mechanic to carefully remove oil sump and check for any sludge deposit over oil pickup strainer. remove from engine & clean carefully reinstall & use fresh new oil.

If the issue persist change the oil pump.

by the symptoms you shared i reckon
a. bad oil filter
b. dirty oil pickup strainer
c. worn out oil pump

thank you..... dear

[SER_GTR]

despite these all

it could also be a bad ungal (Solenoid) or cherry blossom ( VVT-i cam gear) ..inspect these also

[Xulfiqar]

it maybe a bad timing chain too - happens quite a lot on 1NZ

[dani_kk]

Can you please show us the video?
And jab subha gari start karen oil cap khol dena and jese wo awaz ana shuru ho, dekhna kay oil pressure se cap se bahir nikal raha hai ya nai. Agar oil late arha hai then it means bad pump and bad pump humesha bad Hoga. Chaye subha chaye dupehr.

Exhaust related awaz to nai hai? Ya engine k andar se awaz ati hai loha ragar khanay ki???

[pwuser151902690497]

[capsat]

make sure that at the next oil change you are present after drain filling fresh new the oil level is to the mark, after top up let engine idle for few minutes and then check the level again and add if required

[pwuser151902690497]

it maybe a bad timing chain too - happens quite a lot on 1NZ

is it because of motorcycle drive chain type change used NZ series engine and not multi link timing chain we find in modern engine?

[dani_kk]

Not really if this is this case then beams and 2zz both use same time of chain, but it doesn't gives any noise.

[Xulfiqar]

the roller chain is better than the silent bloc style chain. Using bad oil causes rapid failure or missing components like the an oil dam or cup/guide etc or blocked oil hole so the chain doesnt tension properly and clangs and clacks to death.

less rolling resistance in roller chain?
