I have a serious oil consumption problem (1 Quart every 380 miles) and am looking for a Chevy service center that I can trust to replace my rings. I get the impression that my local service and sales center (Potamkin) does not know a thing about my Corvette. I had to bring the oil consumption TSB to their attention and fight hard to get it approved. They finally agreed to do the work March 18th, but I am scared to have these guys take my car apart. They have never done this job and don't seem to appreciate how much I care for my car. Please help in pointing me in the direction of a service center that knows Vette engines inside and out and is familiar with the oil consumption problem.
