do change new one knock sensor brought at singapore spare part shop cost me at $185 & change oil engine to higher grade 10-40 total engine oil, previously use mobil 1 0-40. and all knock ssound are hilang

but Iacv-aac valve also got sound

: tick tack tick tack small sound. so decide to clean before change. dismantle iacv-aac valve as attach pic. choke clean with pertol & sand paper fix back wah lah.

no more tick tack tick tack sound.
Bump: sb3,back to basic before i clean my manifold part till engine. engine can see liao very clean.
my car no power & fc high (makan minyak)
on the right hand side chasis got sound.
morning start engine-> banyak busuk petrol smell & little bit white smoke (smoke a while only after 20 min's smoke hilang).
iacv-acc tick tack sound.
so decide ask my foreman (friend) dismantel manifold part till engine stop.
so my friends dismantle & i start scrubing my manifold part with paper sand & petrol.
found that on the manifold side one of the hole is totaly choke with oil dirt
refer to no 7 , so korek korek korek till clean & wash with petrol. clean throttle body & fix back everthing. at this part i was forgot to clean iacv-acc valve. so drove back to monitor for 1 week.
no more petrol smell when morning start engine & smoke pun hilang

. then deccided to cuci kereta after cuci finish start engine hear iacv-acc valve tick tack tick tack so went back to my friend shop. he told me dismantle iacv-acc valve cuci first before change, after cuci done fix back no more tick tack tick tack sound
Bump: and for right chasis sound, we borrow from kedai potong right suspension set & cv joint set to test it. to isolate the problem when turning or stop got tuck tuck sound. this problem are very frustrated

so my friend say we start from easiet first. dismantle right hand suspension set, fix with borrow from kedai potong & test it. WOW factor are in no more sound :cheers:
so he ask me to test it for 1week before comfirn is suspension set problem.
so far right chasis no sound, engine no longer knock, O2 sensor seem to working again, no more smell petrol, no more white smoke & iacv--acc valve no more sound. very happy hopefully will last.
