so who has had problems using special sealer or head gasket jointing paste /compound on there metal head gasket and who hasn't had problems as I haven't fitted my head yet and the one ive got is the wrc 4 layer one and there not cheap so wanted to make sure it seals properly as I have been told by a few people that they some times seep oil or water ...
