Question about Cars & Trucks
Oil is coming through the bake booster vacuum line. what are the possible problems?
The engine must have excessive blow by from worn rings or the PCV valve is plugged. They make a kit that keeps oil out of the booster it is a canister about the 2/3 the diameter of a coke can and about 1/3 the height. If you don't have one try finding one on an older GM car, they are all the same part. The filter goes in the large vacuum line to the vacuum brake booster.

There are a Couple of Different Variations on the Boosters. Make sure that you have the Correct one First. If you do, Just work it, Some of the Rods are Removeable by the Way.

They need to be bleed again all four wheels but your vacuum pump may be bad since diesels don't have vacuum then have to have a pump, check that the booster one way check valve is good if you can blow thew it both ways it's bad, to bleed start from the wheel farthest away from the master cylinder pump the brakes 5 times and hold down then open the bleed valve keep doing this until you get clear fluid out of each wheel once you have done that if it is still mushy and you know you have vacuum re bleed with engine running this will help push more out with power assist. most like the hard brake pedal had to do with no vacuum check out the pump. You may also have to reset the 2 way check valve if you need help with this let me know.

Sounds like, there is no power brakes if the hose is not connected to the brake booster. There should be a massive vaccuum leak in the engine. The brake booster vaccuum line is a major vaccuum. You should hear a hissing sound when engine is running. Find the hissing noise and replace as nessessary.
