Turbo not working

Hi,

I am new to this site and I just purchased a very nice 1986 Saab 900 Turbo Convertible with 80,000 miles and it. The turbo is making a strange noise and it is not making any boost pressure. Before I remove the turbo I was wondering if there are some things I can check to make sure it is faulty and a replacement is required. Any help would be appreciated.

Thanks,

Brian

Visit Autofthings to review how to clear coat for headlights if you concern. Any help would be appreciated.

Have you tried checking flow of air or oil, or foreign material in the bearings? Because one of them can lead the noise. Also, you can check wastegate actuator if it might be stuck open and check hose going to wastegate. Good luck to you.
