Right, but I found that chasing the threads for the blockoff plate in the HE was difficult. > And we've established that a Type 1 heat-riser block-off plate will do > the trick in the port on the heat exchanger. I know that VW showed a special block off plate, but it was probably the same thing. I know that the usual little type 1 heat riser gaskets work there. > The EGR has electrical connections, right?

I'm sure this isn't necessary, but it keeps things secured and avoids any problems of accidental shorts. This way, you can hear the valve open/close when you turn the ignition on; that's the only effect it has now. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
