    If that comp had mineral oil and you put r401 without changing to alky oil I bet comp seizing up.

    As a last ditch effort you might try some Supco 88, sometimes it works sometimes not.

    I would say oil logged or the oil got washed out of the compressor. I use 409 for 12 systems and have zero problems.

    Yea I agree.

    Sometimes you can add a little AB lubricant and it will help bring oil back
