RCM Group N Baffled Oil Sump Pan (EJ25)

As most are aware the sump pan carries out a vital role in any engine collecting and storing the engine oil before being distributed around the engine lubricating and cooling as it goes. Shortfalls in the standard sump arise when the cars are used on track where oil surge when hard cornering soon becomes a major problem. In simple terms oil surge is a result of the lateral forces being exerted on the oil pushing it to one side within the sump pan. The central positioning of the Imprezas oil pick up pipe can mean that under these conditions the pick up pipe can become starved of oil often resulting in a major engine failure as the engine loses oil pressure placing extreme pressure on the bottom end components.

The RCM solution is a modified ˜baffled version of the standard sump pan which is designed to combat the effects of oil surge via a specially constructed hand made insert or ˜baffle fixed inside the standard sump. This insert dramatically improves the ability of the sump to hold oil around the oil pick up pipe even under extreme cornering by restricting the lateral movement of oil around the sump. In addition to this the top deck of the baffle is fitted with four one way valves which allow oil returning to the sump to pass through but not pass back in the opposite direction when being moved around in the sump. The baffle insert also helps combat the unwanted ˜pooling of oil in the Impreza cylinder heads which can often happen under high cornering loads as a result of the flat boxer engine layout.
