Power valve screw dimensions?

[rgk]

Does anyone know the correct size screw for the power valve butterflies?

I just took my plenum apart yesterday and found EIGHT OF TWELVE MISSING.

Three of the butterflies had fallen down and lodged themselves in the intake. I removed them with a magnet.

This was surely the source of my noise a month back. However, I think that most of the screws were already gone when I bought the car.

It's a wonder the car runs as well as it does. I took a look at the plugs and they look worn and blistered. According to my scan tool, the car runs 15 degrees advanced at idle. Perhaps this is because the butterflies were missing?

In any case, I'd like to find some replacement screws. Would anyone happen to have their dimensions?

If I recall, 15 degrees is normal. The FSM would confirm that. I don't recall which section, but I can look it up when I get home.

rgk: you are one lucky dude.

As a precaution I removed the remainder of the screws and butterflies until I can find some replacements.

I now have a confirmed P1145 and a pending P0011. Might this be related to the butterflies being missing? Or rather a disconnected wire?

I also removed the bank 1 valve cover. In order to do so, I had to remove the VVT solenoid. Maybe this got dirty or clogged? I accidentally dropped some dirt and dust onto the valve train.
