As some of you know i changed the 4 plugs not under the balance bar last week.
Having now got the right o rings etc i plan to change those 2 tomorrow..
However
Since i changed the other 4 and pried the balance bar up maybe an inch but not off i have developed a horrific rattle from that area on the drivers side....
Basically this rattle sounds like a metal on metal high speed rattle. It only does it under load, i.e not when you just rev it... also it does NOT do it when you change down and the revs peak or you hold the revs at any point.
It literally only does it (and its really loud) when you push the throttle, gets progressively worse the more throttle you give it......
Finally i have noticed it seems to have coincided with a loss in torque.....
My first thought is that it is a boost leak from the balance bar..... However the boost gauge (Proofec B II) isnt showing any signs that im not getting the right psi (Im not sure where this takes a reading from however).

Any advice would be most welcome,
