Hi Guys,

Randomly on Saturday morning when starting my car, i've now got a odd noise coming from the engine bay, on the passenger side.

From poking my head around the engine bay, it sounds to be coming from the low rear passenger side of the engine, quite possibly the exhaust manifold or exhaust.

I am hoping to get some suggestions on what it could be, and how i could test for it?

I have recorded a video on my phone and hope someone can pick it.

Please ignore the 'ticking' noise which i believe is just the PCV purge solenoid on the passenger side (as i could put my ear on it and hear it clicking loudly) there is also a slight squeal noise which i believe is idler and tensioner pulleys.

In the video i have put my phone down both sides of the engine, so you can hear the difference between the 2 sides and what noise i mean.

Video is here: https://dl.dropboxusercontent.com/u/10817981/VID_20130526_171358.mp4

Took the car to Ultratune this morning.

Ultratune called back saying the noise the car has and loss of performance was just the left hand side exhaust manifold bolts were loose and so it was losing back pressure.

$76 for a full diagnostics, i'm happy :)

Back pressure is bad in any situation. The term is used incorrectly too often.

Back pressure, or the lack of it, would not cause the issue, incorrect sensor readings because of the exhaust leak would have caused the poor performance.

Ah ok.

This was worded from what he said and honestly I have nfi in regards to exhausts, etc and terms to use.

I'll remember your info though, thanks.
