Oil pressure might be tough, but I rigged an oil temp sensor just to have some peace of mind. Trailtech sells a water temp sensor with M6x1.0 threading that is a perfect fit for the oil check bolt at the bottom of the case below the filter; I routed this to my Vapor so I can set my own temperature points. Then I just routed the stock water temp sensor to an idiot light. Focallength, as mentioned by ifixfords, the cam wasn't the problem, loss of oil was. Either through a (massive?) leak, excessive burning, or pump failure. Need to find and fix that first.
