Hi all, I am currently putting my engine back together after a head gasket job. I bought a gasket kit from atlantic british and seem to have run into a problem. The coolant outlet pipe from the lower intake manifold has an oring (in attached pic from rave). I believe the part number is ERR7202. If it is, it should be in my kit. none of the orings in my kit fit snug around the outlet pipe and i seem to remember it being snug when I took it off. Is this part really ERR7202, and is it a snug fit or a pretty loose fit?
