Rattle gun sound on light acceleration

Recommended Posts

I know this has been discussed and I have read a little bit however just hoping to get some feedback specific to my scenario as it'll be a week before I can attend to the car.

My v36 seems to have a sound like a rattle gun around 2.5k rpm and mainly on light acceleration. As in barely touch the electronic throttle it makes noise, lift fully off the throttle and it goes away completely. So it makes noise cruising around 90km/h to 110km/h, but with a full lift of the throttle or put the throttle down a little more due to a light hill or accelerate and it disappears. 

Seems like the vvt actuator assembly yes? These are electronic so linked with the throttle sensor?

Hopefully an oil flush and change of oil may fix it? I'm guilty of only topping my engine up and it's in need for a service (almost 20 thousand km = shock). It was good oil...

Not sure, but an oil change should help. You NEED to service the V36 at 5,000km intervals - anything else is torture on the engine and will lead to a premature demise.

Is it OK to disconnect the vct solenoid to check if the problem goes away? I realise the engine light is likely to come on.

I'm going on holidays tomorrow so a full flush and Oil change will be done when I return in hope that fixes the problem. Juwt tot two trips left in the car... Hopefully

I'm assuming the solenoids are under the cover. Blue plugs I have read... Other than standard servicing I haven't done any work under the bonnet of the car yet..
