Through experimentation and data acquired from the E36 World Challenge Touring Cars, Turner Motorsports discovered that in long corners and under heavy braking that there was an oil starvation problem in the M50 and M52 engines. This system was developed to keep oil in the sump and eliminate the starvation problem. After several iterations, further testing and data acquisition in the Touring Cars showed that this system eliminates the problem of oil starvation. This is a less expensive alternative to replacing the stock oil pan with the factory BMW M3 Lightweight oil pan, while still achieving the similar results. *Requires Professional Welding
If you have got to the point in your job where you are actually holding your oil pump in your hands, if so, you should send it out for a professional inspection of the flow rate and pressure. The oil pump is responsible for the recirculation of the engine oil and is crucial to the success and life of your engine. Also always replace all the pumps o-rings, seals, gaskets and hardware while you are in there.
