 it is part of the head gasket and is responsible for 80% of HGFs and the L/R gasket is as bad in this area as the MG one What is this fire ring?

Well, if you have a look at the gasket, there are 4 round openings for the cillinders, and the edge of those openings have an extra ring... the fire rings. Maybe the following image make it a bit clearer.  hope this makes some sense |

Fire ring failure would depend on the hardness of the head, and the liner height proud of the cylinder block It's not normally a problem, most seem to be failures of the polymer bead, but there again, who knows  |
