A vehicle comprising an engine having a cylinder block, a cylinder head and a gasket disposed between the cylinder block and the cylinder head. The cylinder block and the cylinder head each comprising at least one bore opening leading to a casting bore within the cylinder block and cylinder head respectively. The gasket comprising a gasket opening having a control gap, said gasket opening being sized and arranged to provide a fluid pathway between the bore opening in the cylinder block and the bore opening in the cylinder head. The control gap being configured and arranged to selectively restrict that fluid pathway such that gas may freely pass through the cylinder block bore opening and into the bore opening in the cylinder head whereas coolant can only restrictively pass through the cylinder block bore opening and into the bore opening in the cylinder head. |
