red top noise from coil pack

[Este510]

Okay straight to the point, what happens is there is a knocking sound coming from my coil pack I think. When I disconnect it, it goes away. I tried switching the coil packs around but it still makes the knocking noise in the same place. :tweak:

Any help would be greatly appreciated.

did you just replace spark plugs? if so the depth of the plug could be too deep

does the sound increase with higher RPMS?

If So you spun a rod bearing.

if the sound does not change with swiching coil packs then why dont you take the valve cover off and take a look you might have a broken valve spring or^^^ a spun bearing more info plzzz!!
