Due to the connecting rod principle for cylinder head bolts in conjunction with the aluminum cylinder block results in a compression of the cylinder block which cannot be reproduced when cylinder head is removed. For this reason, a new cylinder head gasket with the same index number, refer to --> [ Cylinder Head Seal Identification ] Cylinder Head Assembly Overview must be installed when replacing the cylinder head gasket.
