Oiling issues have always been a problem. Whenever the car goes faster the issues come back. Nothing unusual about that, oiling issues have always been a problem for wet sump road race cars.

Tim has tried a bunch of different oil pans over the years as well as different valve covers, dipsticks, breathers, etc. Whenever the performance increases then the g-loads increase and the oiling issues come back.

A dry sump system should solve all of the problems but it costs a bunch and then it all has to be packaged into the car. It isn't easy or cheap but it should solve the various issues that we're seeing.

It is really difficult to package a good oil pan into a stock chassis with headers and a low ride height. Nobody makes a good road race oil pan for these cars so each one needs to be custom built which takes time and money. The R&D process is a little painful when the engine has to be pulled out each time to change the pan.
