    The oil case gasket is too thin and flattens out with age, causing a leak. Quicker if the pump gets hot running all night on new installs. Easy and cheap repair.

    I saw my first last week. The equalizer was leaking bad enough to cause oil failures on a 130hp compressor rack 300 ft away. Just a little 1/2 ton Sporlan in a meat service case.

    The ones I use to work on were Copeland 2-stage compressors with hotgas bypass and liquid injection. The compressors never pumped down, just stopped feeding the evap coils.

    Nitrogen doesn't react until well above brazing temperatures and is a fraction the cost of the other two gases, so it is ideal for working with copper and acetylene.
