And pretty pictures too.

Its embarrising when someone gives me a simple search term "e320 egr' and it works. Mea Cuppa, Mea Cuppa.

It appears the first [and cheepest] things to do are replace the plastic hose with a rubber one, test the vacuum on the EGR and spedo cable the metal tube from the EGR to the manifold.

1] How far [feet] should the cable go to do the job?
2] Where does the crud go that the spedo cable dislodges? Or isn't there that much too be concerned?
3] Can I damage anything with the spedo cable while doing the roter rooter routine?

P.S. Nice b/w over color pik. Worth a 1,000 words.
P.P.S. Speaking of crud - I pulled the Plenum and intake manifold on my Scorpio. It's amazing how much accumulated in there and what a gallon of laquer thinner can do to it.
