Part 5 on the picture. Over time the hose dries up and cracks. The other end of the hose goes to the under the throttle body. Pain in the ass to see. I just felt may way.

The wife was complaining of gas and oil smells. After finding and replacing smells gone and oil consumpion= zero now.

same thing was happening with my M50, turned out to be the valve cover gasket, the gasket got old and started to leak just about a drop or two of oil on the exhaust side of the engine near the rear exhaust manifold, so oil would drip from the gasket and fall on the hot exhaust manifold, it would burn very quickly and smell inside the car, i pulled off the valve cover, used some silicone sealant and now no more oil leaks or oil fumes. hope that helps
