[Vwdiesel] 92 ECO injectors (redux)

[TexasTDI]

To solve the problem of EGR and intake clogging, I disconnected the CCV.
The CCV is the "hockey puck" on top of the valve cover with a little hose
connecting to the air intake hose.  Oily vapors from the CCV enter the EGR
and get mixed with sooty exhaust, clogging everything up.

I plugged the hole in the air intake hose and ran a longer hose from the CCV
down below the car.  It's commonly called the "Elephant Hose" mod.

Also, using the right oil helps.  Use an API CI-4 oil.  CI-4 oils are the
only oils that are specifically designed for diesel engines with EGR
systems.
