Fabia 1.4 - engine cover/oil cap dodgyness!

umm i took the black abs cover off the engine today to check the headgasket seal properly as there'd been some oil coming from somewhere and the oil cap for the engine only 'sits' ontop of the rocker cover. it doesn't actually lock down. now i realise that the oil needs to breathe and cool but surely they could have worked out a better way of doing it! every time i go over real rough roads i end up with oil sitting in the sink around the cap! :thumbdwn:
