Any one give any advice on rebuilding/refurbing water pump on a mk2. Are there any particular pitfalls with this that i need to look out for. or is this pretty straight forward. I know one head will need to be slackened to refit inlet manifold but right hand head gasket appears to be weeping anyway so this will be coming off. Getting water and oil in the vee so hoping doing both will cure this. Bit of a pain as the engine runs really well. :-/
