BMW Burning Oil

Preventing Your BMW From Burning Oil  Under the hood of a 7 Series BMW. At around 80,000 miles, all BMWs start burning oil and may encounter compression problems, or “burned valves”. Valve jobs involve removing the engine’s cylinder head(s), so that the guides, seats and valves can be refurbished. This allows oil control and compression to be restored. Usually, valve train jobs begin by dismantling, cleaning and examining the cylinder head. Heads made from cast iron are “magnafluxed”, to search for hairline cracks. Magnafluxing involves sprinkling iron powder onto the head, whilst exposing the head to a powerful magnetic field simultaneously. After the head has passed this inspection, it is examined for flatness. Undue roughness, warpage or other damage could make the head gasket malfunction. Should the head exceed the maximum permissible out of flatness specifications, it has to be replaced or resurfaced. - All this sounds
