Wastegate rattle

[low_vr4]

Today after taking the VR4 for a nice long drive, once i stopped i noticed a strange rattle which sounds like it coming from the back of the engine. Could this be the wastegate rattling or something to do with the actuator? :|

The car is also due for an oil change but wouldn't be that would it?

Does it increase with engine speed?

Nope, sounds like it goes away when i rev the engine, cant notice it when driving, just idle

Knackered engine mount rattling perhaps?

Too stiff/hard spring in a dump valve.
That's typical if you have dv with adjustable spring tension, i.e. Forge ones. In their manual says: "rattle whilst idle - spring is set too hard'

Could just be a heatshield lose. If its wastegates, then you will here it on overrun. I had it with mine and I adjusted them and it went away for 6 months. It has returned now, but still not as bad as it was originally.

Have just adjusted the spring tension actually, might try loosen it

I have a feeling its something to do with the power steering pump/belt. The power steering pulley seems to have a slight wobble on it and the belt seems to squeak abit. When i put wd-40 on it the noise goes away temporarily.

Mine makes a sound after I boost. It's like a rattle from the rear engine. I know its not the power steering belt cus I just replaced it, I thought it had to do with the turbo. It is hardly noticable tho.

I checked your video out, maybe that is lifter tick?

Honestly, that doesn't sound good. sounds a bit inside the engine knocky knocky. get a mechanic to give you their opinion.

I wouldn't have thought it would be bottom end as it goes away above idle. It could be the power steering belt tensioner bearing?

[low_vr4]

I think its something to do with the power steering belt/pump or tensioner bearing. Sometimes my power steering can be really sensitive and then other times its slightly harder. When i spray the power steering belt with WD-40 the noise goes away. Another thing is when i pull up after a long drive and let the car idle, its about 30 seconds after i have stopped that the noise starts

[BEG4ME]

Pull the belts off and then see if the noise comes out. Water pump driven by cambelt so should be fine to take it for a drive if need be.

EDIT: I mean just the auxiliary drive belts.

could be dodgy tensioner
