You still could have engine oil getting past the vacuum pump and/or the diaphragm in the shut off fastened onto the back of the injection pump. Get two of the small air filters from your dealer (actually, I think they are fuel filters also). Install one in the line coming off the shutoff and the other in the line where the vacuum system branches off from the main line between the vacuum pump and the brake booster. If you have oil coming from either source, this will catch it and identify the source. If the check vaslve remains suspect, squirt carburetor cleaner through it, then blow it out. Often clears things up. Brake booster rebuild kits are available and not too difficulty to work with.
