  1. Just buy an ls series take out. Any ls series. Put it in the car with a dry sump and you are done for many years. Don't worry about squeezing the last bit of up out of the set up. Get it in the car and drive it. Later maybe swap a cam and intake or heads.

     

    When that pukes put another take out in the car.

     

    Good luck. Frustrating I know.

  2. Mike. If the valve is working and it sounds like it did before, is bet you have air in the Accusump. Run the air side up to 60 to purge and then reset base line pressure again. Do it a few times until you get it to work correctly.

     

    Mine did he same thing when I first put it together. Took a few times to get the air out and oil in.

  3. I'm sure you've seen this but

     

    AccusumpTM not filling or filling too slowly

    It should be noted that the standard electric valve units fill slowly. The design of the valve is to ensure that too much oil is not diverted from the engine during refill. These units are recommended for pre-oiling and not for surge control. The EPC electric valve will fill slowly until the pressure threshold is reached at which time it will rapid fill.

    Other reasons for slow or no refill:

    1) The manual valve is not being opened completely.

    2) The EPC is wired incorrectly. When the pressure is above the threshold, the valve should not be energized.

    3) The wrong EPC pressure threshold was selected for your engine's pressure range. The pressure threshold

    should be below the engines normal operating pressure.

    4) The EPC valve may be plumbed incorrectly. The pressure sender should be installed closer to the engine than

    the electric valve.

    5) The electric valve may be installed backwards. It should be mounted so the port marked “IN†is plumbed to

    the AccusumpsTM and the port marked “Out†is plumbed to the line running to the engine. When the valve is

    mounted backwards oil will not enter when it is in the off position.

    6) The feed lines or connecting port is too small.

    7) The pre-charge is too high and not letting oil enter.

    8) The unit is bent, distorted or mounted incorrectly.
