I read on Craig Brace's page that you can disable the VTC by running a ground to the VTC wires, exactly which wires are these though it doesnt really tell, there are 2 wires running from the big harness. to the VTC silenoid, Would I need to ground both or just 1? >_> if so which 1?

 

yellow, but it's been two years so I'd wait for someone to confirm.

 

yellow



i done red, and no telling what fed up



it says it on his site, its just hard to find



YELLOW ground the Yellow

 

yellow!!!! want me to go take a pic of mine? I've not removed the tap I put on there yet. Finished the VTC rebuild yesterday..

 

well I did it and it seemed to make the sound a bit less appearent but it was still there, So I reconnected it and left it as is.

 

How many miles on your car?

 

260,000 KM so like
160k M?

 

I grounded mine at 230,000 miles and it still had a little lifter knock.
Then I added a quart of resilon at the next oil change and it sounds soooo
quiet.Only a little tap on start up. Seems to idle a bit radical
but no more time bomb ticking.

 

The last time I heard a story like this, it wasn't the VTC's making noise. It was the timing chain tensioner on the front/left cylinder head. The guy grounded the VTC's properly but the noise remained. He didn't know what to make of it so he just shrugged and went about his daily business. One day the tensioner completed its road to failure and threw the chain. It destroyed the valves... Your car is about the right mileage for this to be an issue, have it checked or start planning on a blown engine.

 

that sounded like me

grounded the vtcs and still had that ticking time bomb noise

replaced the tensioners and put it back together

1000 miles later and boom timing chain goes

have it checked out

 

hmmm. how loud is the tensioner sound though?

I mean my sound litteraly sounds like


as i accelerate ONLY,
vroom click click click click click but its not a fast click, and it doesn't really go up so much with rpm which is why I would doubt the tensioner

 

so we should worry about replacing the tensioners and chain before it blows up?

 

If it was me, yes. If I still have the car at 150K I will do them then. I've seen to many posts where the mileage hits 160-180K and *BOOM* goes a timing chain. I've got an extra VE engine that I pulled a VTC from and its tensioners are pretty worn, they have 163K on them. They are bad enough that if I had seen them in an operating car, I'd repalce them. Of course there is no way to check the chain...

 

is it a fairly pricey / hard job to replace the tensioners? :|?

 

My max spent its first 9 years as a city car doing stop & go, had 58K miles when I bought it 4 years ago and now its at about 101K. I have the ticking noise and was planning to ground the VTCs soon, so I'll see if the noise remains once I do.

Does the chain tensioner go bad with both age and milage?

 

It actually wears, so my $0.02 is mileage. I can get pics of the one from my 163K engine later this week (its at my parents house).

 

I know this is an old thread but i was wondering if any one has a link on how to ground the vtc i have searched the site and no luck and craigs web site no longer exists thanks Jesse.

 

Have you already checked the stickies? General Maintenance Reference

 

All i can find is how to rebuild them(which i plan on doing in the next few months)but i would like to disable them for now,i just need to know which wires to ground and where they are located. Any help would be appriciated thanks in advance Jesse.

 

bump

 

....

 

There's a yellow wire in VTCs' harness which needs to be grounded, thats all.

 

all right man thanks
