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.

Features

  • Dramatically improves the ability of the sump to hold oil around the oil pick up pipe, improving reliability and limiting any chance of engine failure when driven under hard cornering.
  • Supplied with our Titanium Magnetic Oil Sump Plug to attract any unwanted metallic material.
  • Can be used in conjunction with our Oil Sump Baffle Plate for the ultimate in oil protection.

Please not that this pan is not compatible with the Killer-B oil Pickup

The increasing popularity of track days and other such events coupled with the search for ever higher bhp figures has highlighted some alarming shortfalls in the standard sump fitted to the Impreza from the factory.

Starting life as a genuine Subaru oil pan to ensure perfect fitment the RCM Baffled Sump is then re engineered removing much of the relatively ineffective standard internal shelving system and is then re manufactured to accept our specially designed removable Group N alloy baffle insert. This insert incorporates x4 heat and oil resistant nitrile one way valve flaps to keep the oil exactly where it needs to be even under hard cornering on track or during competition use. The RCM Baffled Sump kit also features an additional -8 boss for easy plumbing in of a return to sump hose from an oil catch tank system such as our RCM2030, RCM2031 and RCM2283. Supplied with full installation instructions , x14 genuine Subaru Sump bolts and one of our RCM Titanium Magnetic Sump plugs all pre lock wired and ready to go!
