8) this is similar to what the integral valve looks like inside. This is NOT the one on the n62. I think this is the external one mounted on the back of the m62. I might be wrong though. The passage toward the bottom is the oil drain to allow the oil to flow back into the engine. If it is plugged and the oil pools then it will get sucked not the intake manifold. Also, under high vacuum like acceleration, the central port is closed by the diaphragm. It only allows flow from the crankcase into the intake under light vacuum. I think this is what was not sealing in my problem. Under acceleration the high vacuum would suck pooled oil out of the valve and directly into the left side of the manifold and into the cylinders.
