Without enough oil to keep things properly lubricated, parts in the engine won't have any protection when they rub together. Oil pumps, like fuel pumps, are designed to provide far more than the required pressure and volume, so by the time there are symptoms, the pump is performing very … To check if the problem is limited to one cylinder, you can unplug one spark plug at a time when the motor is running. Some of this information may not apply to some newer brake systems, which feature integrated electrohydraulic boosting, but the theory is similar.
