So, after some research, I found that the mechanism below the carb, but above the EGR is the Manifold Vacuum Fitting. I have two 4mm hose hookups on mine but I cannot find a schematic that shows what they are suppose to be hooked too. With the engine running, they both have a vacuum. If I plug one of them with my finger, the engine idle doesn't change. If I plug them both, the engine idles rough and slow. I plugged one of them and put a vacuum valve on the other. I know this isn't how they are supposed to be hooked up and would like to fix this. Just short of rebuilding the engine, I have got to find out where the oil is coming from at speeds above 35mph.
