Topic: Lemony Oil Accumulators

Anyone ever use an oil accumulator other than a Accusump or Moroso? I see OEM accumulators on eBay that are from Mazerati, BMWs and Mercedes. No clue if they're equivalent or what the volumes are. But they're cheaper than a used accusump.

Or got an alternate idea I'm missing? I even saw some accumulators intended for cooling large diesel turbos at shutdown that might work. But I'm guessing they output at a slower rate than one intended for oiling.

That's an oil catch can, not an Accusump replacement. Get the real thing, it's worth it.

Re: Lemony Oil Accumulators

Yes. The first car I raced (1984 honda D16A1) had an empty fire extinguisher bottle used as an accusump. You just mount the bottle with the mouth downward so its a dead end, with air in it. As the oil pressure builds it fills the bottle and pressurizes the air to what ever pressure the oil is running at, when the pressure drops the oil flows back into the engine. Not sure if it saved the engine, we also built baffled oil pan to help overcome the high rod bearing failure rate of the honda engines. That car also had an empty fire extinguisher bottle as a fuel surge tank, which is now not legal. we could run that car to completely empty.

In the 72 Valiant that I ran, with a slant 6, I bought a used 3 quart Accusump and use that. Again not sure if it was ever needed. But we never failed an engine because of reduced oil pressure in corners. We did fail an engine because the oil pump gear was chewed up and the pump stopped pumping.
