Ive recenlty noticed a rattle/knock coming from the engine, which can be heard at idle, increases when i push the throttle, and when im driving the pitch and frequency increases with speed but only seems to be audible when i push the throttle.
There has been no loss of power or performance that i have noticed.
video of the noise:
I will try to get one while driving as soon as.
any would be greatly appreciated as i do not have any vehicle mechanic experience but i do have a mechanical background.
