It's going round in circles a bit with your motor isn't it..seems it was basically running ok.. anyways i think what you need is an unbiased chap into vwdubs to look at it and give you the low down.. maybe someone here could help if they're local enough to you..
Maybe just refresh us on the history of it when your bought it? any doubts about the mileage..service history etc..
I'll be surprised if it's a serious engine problem on these, unless it's been severely neglected in the past.
Yes you may have an oil leak or and or a water leak as well as some other basic typical problems on these cars but they could be just simple remedies or things that need service attention.. yes there could be other reasons why your sprouting leaks such as head gaskets/pressurising but we're just guessing a bit.. hard to know without more info or a hands on recky..
But, don't give up just yet ok
