Abstract
An engine is provided with a cylinder liner that extends beyond the surface of the crankcase surrounding the cylinder. When the engine is oriented in an inverted V-block configuration, the extension of the cylinder liner provides a barrier to oil that can pool on the crankcase surface and otherwise enter the interior of the cylinder, absent such a barrier.
