Hi All , I managed to remove the rocker cover ( many thanks from YOU all) . But nobody has said how you replace the oil seals which are not easy and at one point I tried heat from my camping stove trying to melt it off . But these seals are designed to withstand heat so that didn't work. All of threads talk about replacing the rocker cover ! I don't the money for that or the time, as need my car for work. Peter0003
