Oil in the intake manifold is one of those automotive issues that rarely announces itself with a dramatic noise. The symptoms are often progressive, starting as a minor annoyance and escalating to a complete engine malfunction if left unchecked.
Understanding Pressure Imbalance in the Intake Manifold Caused by Oil
However, if the PCV valve sticks open or the system becomes clogged with oil sludge, it can create a vacuum leak or excessive pressure. The most frequent offenders are often related to the valves that manage crankcase pressure or the physical barriers that separate oil from air.
This smell indicates that oil is present on the hot surfaces of the intake and cylinders. These seals act as barriers, preventing oil from the valve guide chambers from migrating up the stem and into the combustion chamber during the intake stroke.
