Hi, I'm to replace one of the plugs (the top one) on the inlet carb manifold on our 1973 +8 RHD. The mild steel plug has rusted to an extend that cooling fluid seeps out. I've ordered the plug, but unsure how to best remove the old and rusted plug and, how to gentle insert the new one. I was thinking of freezing the new plug and gentle hammer it in place by using a plastic hammer. But how to get it 100% tight? Using a fluid gasket like Blue Hylomar? Any experience on the forum? Any advise and views are most welcome. Cheers /Finn
