thanks for all the responces...
I now have a good idea where to start anyway (I hope it's not the intake manifold gasket). Granted I only payed $2K for the car a year ago, it's been good to me. I could pay out more than I payed for the car to fix some problem, valve guides etc, but I wont. So hopefully the problem is something I can fix myself in a short amount of time, while not spending loads of $$$$$
