Cosworth Oil Control Baffle

Oil control can be a problem with high performance and high revving Subaru engines. High crankcase pressure along with the horizontal engine platform restricts rapid oil return from the cylinder heads to the oil pan. Pressure builds in the heads and crankcase causing massive blow by and power loss.

We have engineered the Oil Pan Baffle with diverters to control oil returning from the cylinder heads to the pan directing it away from the crankshaft. In addition, one-way valves prevent oil from re-entering the upper crankcase chamber and thus limiting blow by and preventing oil starvation during hard driving. They are manufactured from stainless steel and install between the block and oil pan on both EJ20/EJ25 series engines.
