You all were right! Thank you so very much!

So, not only do I have a leak, but leaks:
The line with the yellow check valve and hear it on the passenger's side of the firewall

A partial leak in the V.C.V. (I.I.R.C. the name of the device on the injection pump for the automatic transmission)

The worst is the black with red strip going to a device on the firewall. One line leads to the blue saucer.


Further, I have engine oil in the lines which I used to not have.

Vacuum pump is easily reaching 20p.s.i. and then tops out at 23p.s.i!

So, now what?

Is it shutting down okay? Engine oil in the lines is usually caused by a bad shut-off valve (round metal device attached to the rear of the IP).

Thank you so very much!

Very slowly. Tried pulling the line but was unable. Just need more time so can get under the dash and test there.
