Hi I have a 1981 porsche 924 turbo,with 65,000 miles.When I start it up black smoke comes out of the exaust,and when I drive it,it seems to rev a little high.Some friends said it might need new piston rings,but I don't know.Could you tell me what you think is rong with it,and about how much it will be to fix it. THANKS.
