36 --- White/blue smoke (caused by oil burning)
Cloud of smoke released upon starting, especially if machine has been parked on side stand or if engine is still warm. This appears to be a characteristic possessed by all K-series BMWs to a greater or lesser extent, but should reduce considerably as the pistons and rings bed in. Provided little or no oil is used, there is nothing that can be done about this, other than to use the center stand at all times. If oil consumption is significant, or increases suddenly, a full engine strip will be required to investigate the cause.
Piston rings worn or broken. Breakage or wear of any ring, but particularly an oil control ring, will allow engine oil past the piston into the combustion chamber. Overhaul the cylinder block and pistons.
Cylinder block cracked, worn or scored. These conditions may be caused by overheating, lack of lubrication, component failure or advanced normal wear. The cylinder block should be renewed.
Valve oil seal damaged or worn. This can occur as a result of valve guide failure or old age. The emission of smoke is likely to occur when the throttle is closed rapidly after acceleration, for instance, when changing gear. Renew the valve oil seals and, if necessary, the valve guides.
Valve guides worn. See the preceding paragraph.
Engine oil level too high. This increases the crankcase pressure and allows oil to be forced past the piston rings. Often accompanied by see page of oil at joints and oil seals.
Cylinder head gasket blown between cam chain tunnel or oil return passage. Renew the cylinder head gasket.
Abnormal crankcase pressure. This may be caused by blocked breather passages or hoses causing back-pressure at high engine revolutions.
