I desperately needs help with my 1989 Jetta 2 CLX. It spills oil and I end up having to top-up every morning. I checked the oil filter n realised that there is some oil residue there (might be the cause) and also realised that there is some oil just under the carburator (suspect tappet gasket). The buzzer starts after a few km and the oil light starts flashing. Anybody ever experienced this?
