vacuum issues keep me posting. basically i'm trying to figure out if it's the IP or not. from everything i've read it seems like it should be that but.....

-leaking oil from the ignition tumbler/diaphragm.
-doors won't lock.
-car won't shut off but does shut off if i plug off the doors and the resovoir and then it takes 5-10 seconds.
-tested the IP and when give a pull from the mityvac the car shuts off and it holds vacuum.
-brakes work fine. doesn't seem to be any oil in the vac line going to the brake booster
-i'm assuming, maybe incorrectly that the vac pump is fine. i will test tonight. i should test at the break booster correct?

also; anyone have any advice about getting behind the dash to pull the two brown lines going into the ignition tumbler? and is there a check valve behind the dash between the firewall and the front driver's side door lock? one schematic i've seen shows one but i'm not sure if i read it right
