VVT Solenoid removal

[hoopsbhoy]

Is the clutch standard?? Sounds clutch related tbh, possibly the release bearing.

?????

id be suprised if it was anything but the sprocket

Clutch is brand new, literally under 1k miles on it It's not standard, it's uprated but can't remember the exact make/model.

On a clutch note though, it does whine slightly when cold. When I first start her up in the morning it sort of groans the first time I press it. It only happens once and then goes back to being completely normal

I am almost certain it's the sprocket, however, I really taught disconnecting the solenoid would stop the rattle... However, once it was disconnected the rattle was there even when in gear, driving, idling basically I couldn't stop it no matter what I did haha.. Once I reconnected the solenoid it immediately stopped and was only there when the engine was warm & idling.

It has to be something to do with the oil... Once the oil warms up, it gets thinner and somehow it's not doing its job. When the engine is cold there is no rattle whatsoever. I'm going to change the oil again over the next few days with a decent fully synthetic oil (10w60) and see if that does any better

Again, thanks for all the replies/advice.

Ya once the sprocket is "working" it shouldnt rattle as the oil pressure is up, disconnecting the solenoid would only make it worse (rattlying wise)

If you remove the vvt all together, you loose power and torque, unless you get management (Power FC, Nistune, or the likes) and map the car without VVT.. But then when you look at all the hassle, fitting a VVT pully is cheaper. Its not a pig of a job for anyone that knows how to do it, I can do them in 20 mins now, thanks to doing 100's of them

Also disconnecting the VVT solenoid will make no difference to a vvt rattle, it is basically disconnected until you put the car in gear and touch the throttle, then the vvt is switched on.

a rattle from the vvt? is the vvt still working? do they stop working?

[Dermot]

When they only rattle on idle, and stop rattling when you select a gear and go to move off,they are still working.
But when they get that bad that they are rattling all the time, then they arent working at all

That's interesting - I'm getting a NIStune ECU/map installed over the next month or so, could I essentially request that the car is mapped without VVT ? Would you say I would loose out in allot of power ?

I didn't know that, it is exactly what happened but I guess I just expected it to be the opposite haha.

Yep, as above, I expected it to be different but what you are saying is exactly right.

VVT still works fine

When they only rattle on idle, and stop rattling when you select a gear and go to move off,they are still working.

Fingers crossed that doesn't happen, I couldn't bear that noise all the time !!


If I was to change my oil with a much 'heavier' fully synthetic oil would/could that have any positive impact on the rattle ?

Thanks again lads

You can try change the oil, I use 10w60 or 15w50 motorsport oil all the time on sr's.

Yes, you can get your VVT pully removed, and get the car remapped with a nistune, or power FC and you will hardly notice the vvt gone.

But the standard ecu is mapped for it, so if you just remove it on the standard map, you loose all your low down power and torque, top end is still the same.
