This noise only started recently, however up to this point i have been getting a knocking noise while the car has been in Drive and stationary for a few months i posted this issue a while back where the general comments were that the exhuast was more than likley knocking on the tranmission tunnel or gearbox as there is a common thing apparantly so put it down to that - again no loss in performance or random noises or blips/misfires from the engine.
Over the last couple of days i have not really been driving it hard at all. I only noticed the noise when i was at traffic lights and ended up switching the stereo off .. then i heard a knocking noise when the car was in N, i then put it in Drive while stationary and it got alot louder, so not sure if these two noises are linked or just this new one is making the other one seem louder.
The noise is engine speed realated but only happens at idle, when you rev to 1k it gets faster about (im guessing as i did not see the rev counter) 2.5 -3k it goes away compleatly, then when you let off it comes back at idle.
Your right the video is not great but to be honest the sound is exactly the same, but whats being filmed is the intake cam sprocket (as this seems to be where the noise is coming from or that area anyway) i will see if i can do another video tonight or during the day in friday.
I have done lots of searches on the forum for noises etc, some of which i have found that some knocking is due to the Torque converter on the way out, however this is accompanied by slipping of the autobox and odd behaviour and i cant see why if it is the TC why it sounds like it coming from the front of the engine so have dismissed that as an issue.
I will try to do the Aux belt check (taking it off etc) and seeing if the noise is still there, if it is then i will take all the covers off the timing belt area and see if i can look at this Cambelt tensioner and see if the noise is coming from that if it is i will get the parts and replace all the tensioners and all belts etc.
If i still get the noise and cant locate it i will book it into a garage and see what they can do.
Anyone reccomend Toyoda Tech in Southampton at all??
