Power Valve rebuild

[Gas Stu]

Hi Gents,
My power valve rattles on Idle and I want to freshen It up a little....Any Ideas on what should be replaced? Such as bearings etc...

Thanks

Disassemble, clean, and replace bearings. Bearings are very cheap, I replace them every top end job. Under the right side PV cover, make sure the actuator plate is in contact with the stop bolt with just a very slight(barely any) amount of preload with the engine off. If it floats over the stop it will rattle more at idle, but a small rattle is normal. This can be adjusted under the sidecover if neccessary.
