VVT Pulley

[BudakSiol!]

Hi guys,

Based on the old threads, it seems refurbishment/recondition of the VVT Pulley is the best way to eliminate the famous 20V diesel sound and also to make sure your VVT engagement is in tip top condition.

Questions to users of this refurbished VVT Pulley though, after months/years of using it does the refurbished VVT Pulley still functions to engage the VVT and does the diesel sound appears back again? I guess in summary after refurbishing the VVT Puilley, has it lasted you till now or the diesel sound came back and engagement of VVT been an issue again? Thanks.

Interesting question.

Also curious of the above and is it worth buying a new vvt pulley or refurbish? And where can we find new ori vvt pulleys?

done this... and use it for more closed to 2 years without the sound coming back...
now on the second refurbished pulley after some issue on the TODA intake pulley...
have to activate back the VVT...

i do recommend this...

once a wise man said...when you service the VVT pulley, it's better to install a VVT light indicator... :P

I've heard the new vvt pulley ori one bout RM800 at Win Hin...dont know they have ready stock or need to order

VVT pulley lasts about 100,000km, not sure where I read bout it. Its time to change it when the "diesel sound" is noticeable after the engine is fully warmed up. If the sound doesnt bother you, just leave it as is... as long as VVT is working fine and you "get the feeling"

 

[feipepe]

oooic...meant that when heard the sound like diesel "tak tak". but last time my silvertop got very lousy the diesel sound. after that i tries to adjust the distributer angle..now become ok liao...shall this angle distributor is also the factor influence the life-time VVT?
some more, if the VVT totally malfunctional, what is the effect? except have the diesel sound "tak tak"?

yup...
but the only thing you won't notice is the VVT lag and earlier close...
due to the position of the pulley...
well.. maybe something to ponder about...:hmmmm:

hahahaha...i'm not selling...i'm just informing you guys... :proud:

20V engine is on old engine...most of the engine need to do all this thinggy...
might wanna look into ECU lifespan, clean the TB, fuel filter, fuel pump, wiring (especially SVT model) n so on...

I've heard a few 20V as thier VVT pulley being serviced...the sound was beautiful..especilly if they using Veloctiy Stack (metal / aluminium type)..."shhrrrooottttt" then quite down...no more "diesel" trade mark sound of 20V... a unique sound...

WARNING : Don't stand to close when wigh reving on idling...afraid it will bleed your ear ... :P :P

bleed the ear + wet your pants hahahaa

U Got PM...!!


First of all...here's some pictures of VVT pulley (VVT-i and DVVT also)
:: VVT Pulley internal parts :: November :: 2008

All parts need to be service....VVT pulley is no exception.

ECU will sent signal to Oil Control Valve (OCV)...OCV will activate , and rotate 30degree the intake valve...Those 30degree movement using a gearing system which pushed by lubrication.

If it's lubricated, sooner or later it will need a service...same goes to human...heeee...if you know what i mean... :P

As mentioned by pcmoddingmy ...100,000 km is the service interval for it...and i believe most of 20V engine have reached that mileage...

So it would be best to service it.
If you don't intend to service it, it's still ok.
But take note of what meg_omen mentioned.

For me using custom intake pulley is not an option (for me) ...as I've read some article or heard about it can really recall...if you running high-cam lower then 272...it would be best to run it with VVT pulley...that would be the best setup for daily drive car...

It's up to you...
