Hey, pipe cleaners are perfect for cleaning soot out of vacuum lines.
The fit right in there and pull the soot right out better than a drill bit.

You can fold them in half and double the size for bigger orifices. Works great.

I will go to sears and get the mityvac and the wrenches for the glow plugs.

How do I test the EGR?? Does anyone have a good reference for what type of vacuum each switch should be pulling???
