I made an accumulator for my car. The total volume of the cylinder is 1.6 Quarts. Obviously, the whole thing will not fill with oil, because of the compressed air in it also. My question is, with an accumulator, does the oil level in the engine go up? After you shut the engine off, the oil that's in the accumulator will drain back into the engine, so the level will be higher than before. Am I right?

I'd be especially interested with those that have the 1.5 quart Moroso accumulator, becuase that's about the same size as the one I built.

Thanks,
Randy

yes the oil level will rise when the engine is off. just add what ever you think the oil accumulator will hold when the engine is running to the capacity of the pan. When we ran a moroso accumulator we always added the 1 1/2qt to the pan.

I put a 1/4 turn ball valve inline to the acc.. before you shut it down turn the valve off, before you start turn it on, it prelubes , and it wont foul up your dipstick reading when the engine is off.

I recommend adding oil to make up for 3/4 of the volume of the accumulator. You could short this a little and maybe pick up a very little power but on a short track engine I think I want oil level at stock with the accumulator full.

If you are quick, run two hard laps, come in jump out and feel up and down the accumulator. Where it changes from hot to cooler is the line where the oil comes to.
