Good advice Kevin. I am very concerned about the blue smoke. My 993 with 35k miles does not emit blue smoke when it is started after sitting for over a month. I have searched the archives and the various opinions on how much smoke is unacceptable. The owner would not quote a figure on oil consumption. So if it is the guides it is now a question of how much I should pay for this vehicle. The problem is that almost all cars with over 100k have this potential issue looming.
