At around 80,000 miles, all BMWs start burning oil and may encounter compression problems, or “burned valves”. Eurobahn is your BMW Greensboro NC Service Center and 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.

Now, attention turns to the guides, seats and valves. The guides are inspected for wear, and they are virtually always worn. Hence, they have to be either relined, knurled (where the bore size of the guides is reduced, by cutting grooves into the guides’ interior diameter) or replaced. The cylinder head seats are either ground or cut, to repair the sealing surface.

Each valve spring is examined and tested to ensure that it is still able to maintain the correct pressure. The keepers, spring retainers and other components are examined as well. Any damaged or worn hardware is replaced. Then, the valves are fitted into the head and leveled to restore the correct valve height.
