I plan on keeping it a while longer. While replacing the tires this week, the technician noted 2 things- the tension strut bushings were worn, not badly, and I know that is a common issue with this mileage, but he also noted oil leaking from the vanos solenoid gaskets on both banks. Is this a common issue at this mileage? Is it a DIY job? He quoted me about $350 to do it.
Thanks for your help, great site, I should have discovered it sooner...
