Hello All, Had a very slight weep from the water-rail gasket . I have removed the rail and found there is a metal gasket which appears to have paper gaskets either side . The replacement gasket is just a paper gasket . Fitting just this paper gasket causes the rail to leak worse then before . I have fixed the flange end first & slightly spaced out the allen bolt fixing . Anyone else had a metal gasket here on the waterrail ? Thanks in advance
