Hi all, I'm not sure if i'm posting in the right thread however I'm sure someone may have good advice for me. My 07' Mini S now sits at Passport Mini with two broken exhaust valves in Cylinder 4. In order to find this they completed a full engine tear down which I'm not sure was necessary to find the two broken and chipped valves. Passport is now Asking for $4,000 to replace the two valves. Has anyone had this issue before and is 4 grand worth the repair. The car has 68000 miles on it and I still owe a great deal to pay it off. I purchased it 6 months ago. Thanks again Greg
