Chester,
Thanks for the reply. Should I have it this way:
A line from the oil breather at the bottom of the engine to the pcv, to a "T". One leg of the "T" goes to the intake manifold and the other leg of the "T" goes to the Vac pump.
Then another line from the Vac pump to the wiper motor.
And thanks for the tip on the oil. I bought an ebay rebuilt vac/fuel pump and it happened just as you said with blue smoke etc. It was replaced with another rebuilt and although it doesn't smoke, it does have oil in the line from the vac pump to the "T".
