As a newbie to Viperdays (last weekend, thunderhill CA), I took the "rookie" class. Skip Thomas did a great job familiarizing us with the ins-and-outs of these unique cars.
He did spend disproportionate amount of time explaining the PS fluid reservior problem - bottom line, as mentioned, was thermal expansion the different materials of the reservior vs. the cap. His solution, as stated many times above was, everytime you're under your hood, you should have a hand on that cap checking it for tightness before you close the lid. This thing sits right over the exhaust manifold for crimmony sake, it's important to check it.
[I sorta wonder if the yellow RT/10 guy's fire (condolences) was the result of someone at the dealership screwing around under the hood.]
