only by the MityVac, you're good to go."
So...help me review...
There are only two places oil can get into the vacuum system: the vacuum
pump and the shut off valve, correct?
If I put the Mity Vac on the currently installed shut off valve, its hold
vacuum all day long...now I'm kinda stumped.
If the vacuum line to the shutoff holds vacuum (and shuts off the
engine) it's NOT the valve. You CAN get engine oil into the lines from
the valve or the vacuum pump or transmission fluid (on cars that
modulate transmission operation with vacuum) from the transmission or
brake fluid from the vacuum booster. I can't think of anything else -
any other suggestions?
